how might a differejce in the mass of the pod change the amount of force needed to be exerted by the thrusters to stop it

Answer:

The first picture/option

Explanation:

The first picture/option shows the best way for Rafael to set up the investigation.

The experimental set-up must be in a sloppy position in order to simulate the condition that is characteristic of the bottom of the hill where he stays. Hence, the two soil samples must be tilted in order to determine if the grass can help to stop the washing down of the soil from the top of the hill.

The two options following the first option do not fulfill the condition of the same treatment. Both soil samples must be subjected to the same treatment condition in order for the outcome to be valid. The last option could have also been admissible but did not simulate the hill/slope conditions of where Rafael stays.

To set up his investigation on whether grass can help stop soil erosion on a hillside, Rafael can follow these steps: 1. Collect two samples of the same size and type of soil. This ensures that the only difference between the two samples is the presence of grass.

2. Place each sample of soil in a small tray. This allows Rafael to contain the soil and prevent it from mixing with each other.

3. Pour the same amount of water onto both samples of soil. This ensures that the water input is consistent for both samples, allowing Rafael to compare the effects of grass on soil erosion.

4. Use a large tray to collect water that may flow through the soil. This allows Rafael to measure and compare the amount of water runoff from both samples. By collecting the water, Rafael can determine if the grass on the hillside helps to retain more water and prevent soil erosion.

By following these steps, Rafael can compare the water runoff and soil erosion between the sample with grass and the sample without grass. This will provide him with evidence to determine if grass can effectively help stop soil erosion on a hillside.

Answer: Vx = 2.5m/s and Vy = 0m/s

Explanation: The ball is rolling horizontally on the floor, meaning there isn't a change in the vertical position, only horizontal. The ball is rolling with pure horizontal motion and isn't moving in the vertical direction.

Responder:

Explicación:

Las fuerzas que actúan paralelas al plano son la fuerza de movimiento y la fuerza de fricción.

La fuerza de movimiento Fm = Wsinθ y la fuerza de fricción Ff = nR donde;

W es el peso del objeto = mg = 30.0 * 10

W = 300N

θ es el ángulo de inclinación = 28 °

n es el coeficiente de fricción = 0,20

R es la reacción normal = Wcosθ

La fuerza paralela al plano que se debe ejercer sobre el bloque para que se eleve con rapidez constante será la suma de la fuerza de movimiento y la fuerza frictioal (son las dos fuerzas que empujarán el cuerpo hacia arriba del plano)

Fuerza total requerida = Fm + Ff

Fuerza total requerida = Wsinθ + n (Wcosθ)

Fuerza total requerida = 300sin28 ° + 0.2 (300cos28 °)

Fuerza total requerida = 140,84 + 52,98

Fuerza total requerida = 229.17N

Por tanto, la fuerza paralela al plano que se debe ejercer sobre el bloque para que se eleve con rapidez constante es aproximadamente 229,17 N

The coefficient of kinetic friction will be 0.376

The quantity of decelerating force between two moving objects is known as kinetic friction, also known as sliding friction or moving friction. Understanding this is necessary to comprehend the coefficient of kinetic friction, which is calculated by dividing the force needed to keep an object moving by the force holding the two sliding surfaces together.

Given:

Mass of sled (m) = 50 kg

Force (f) = 2.30 x 10^2 N = 230 N

Distance (s) = 5.55 m

net work done on the sled = 2.50 x 10 ^2 N = 250 N

Acceleration due to gravity (g)  = 9.8 m/s^2

Coefficient of friction = μ

Lets first calculate the frictional force (ff)

ff =  μ x m x g

= μ  x 50 x 9.8

= 490 μ

Work done on the slide by the applied force (W1)=  f x s = 230 x 5.5 = 1265 j

Work done on slide by frictional force (W2) = ff x s = 490 μ x 5.5 = 2695μj

The work done by the frictional force is now deducted from the work done by the applied force to create the net work.

net work done = W1 - W2

250 = 1265 -  2695μ

2695μ = 1265 - 250

μ = 1015 / 2695

μ = 0.37

Explanation:

The tendency of an atom to gain or lose electrons in a chemical reaction are given by its electronegativity and electropositivity respectively

Electronegativity is a measure of an atom's capacity to attract electrons from neighboring particles, with atoms that are more likely to gain an electron, being described as having a higher electronegativity

Electronegativity increases across the period with increasing number of valence electrons, therefore, elements with five, six, or seven electrons, which are located on the far right of the periodic table are said to have higher electronegativity and therefore more likely to gain electrons in a chemical reaction

Electropositivity is the quantification or measure of an element to donate or give electrons and become positively charged ions in a chemical reaction

The fewer the number of valence electrons an element has, the more likely the element will undergo a reaction by donating the valence electrons to a more electronegative atom and become positively charged

Electropositivity decreases across the period and therefore, elements with one, two, or three valence electrons which are located in groups I, II, and III, are more likely to lose electrons in a chemical reaction

Kinetic energy is DIRECTLY PROPORTIONAL TO MASS AND VELOCITY

The fundamental period (To) of a signal is the smallest T for which it repeats. Frequency (Wo) is the reciprocal of To. Example: To = 0.5s, Wo = 2Hz.

The fundamental period (To) of a periodic signal is the smallest positive value of T for which the signal repeats itself exactly. The frequency (Wo) of a periodic signal is the reciprocal of the fundamental period,

Wo = 1/To.

To find the fundamental period and frequency of a signal, we need to analyze its waveform.

First, let's identify the period of the signal. The period is the horizontal distance between two adjacent peaks (or troughs) of the waveform. If the signal repeats itself exactly, it is periodic.

Once we have identified the period, we can calculate the fundamental period (To) by measuring the distance between two adjacent peaks (or troughs) and taking the smallest positive value.

To calculate the frequency (Wo), we can use the formula Wo = 1/To. Here's an example to illustrate this process:

Let's say the signal waveform repeats itself every 2 seconds. This means the period is 2 seconds.

To calculate the fundamental period (To), we measure the distance between two adjacent peaks (or troughs) and find it to be 0.5 seconds.

Therefore, the fundamental period (To) is 0.5 seconds.

To calculate the frequency (Wo), we use the formula Wo = 1/To. In this case, Wo = 1/0.5 = 2 Hz. So, the fundamental period (To) of the signal is 0.5 seconds and the frequency (Wo) is 2 Hz.

Answer:

B) t = 1.83 [s]

A) y = 16.51 [m]

Explanation:

To solve this problem we must use the following equation of kinematics.

\(v_{f} =v_{o} -g*t\)

where:

Vf = final velocity = 0

Vo = initial velocity = 18 [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time [s]

Note: the negative sign in the above equation means that the acceleration of gravity is acting in the opposite direction to the motion.

A) The maximum height is reached when the final velocity of the ball is zero.

0 = 18 - (9.81*t)

9.81*t = 18

t = 18/9.81

t = 1.83 [s], we found the answer for B.

Now using the following equation.

\(y = y_{o} + v_{o}*t - 0.5*g*t^{2}\\\)

where:

y = elevation [m]

Yo = initial elevation = 0

y = 18*(1.83) - 0.5*9.81*(1.83)²

y = 16.51 [m]

Object 4 with a density of 2.3 g/cm³  would sink in honey, which has a density of 1.4 g/cm³, therefore the correct option is option D.

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

The mathematical formula for density is given below

ρ =m /v

where ρ is the density of the substance

m is the mass of the substance

v is the volume of the substance

As per the law of floatation, the objects those have less density than the honey do not sink in the honey which has a density of 1.4 g/cm³.

As per the given options, object 1 has a density of 0.9 g/cm³ which is less than the density of honey 1.4 g/cm³, therefore it would not sink in the honey. similarly, objects 2 and object, 3 have a density that is less than the density of the honey, therefore they would float instead of sinking in the honey.

The only object 4  has a density of 2.3 g/cm³ which is more than the density of honey, therefore it would sink on the honey.

Hence, the correct answer is object 4.

The molar specific heat ratio \(\gamma =\) \(C_p/C_v\) for the air is 1.40. Suppose the same amount of heat is instead added at constant volume. The temperature increase at constant volume is approximate \(71.43^0C\).

In this scenario, the molar specific heat ratio \(\gamma = C_p/C_v\) represents the ratio of the specific heat at constant pressure (\(C_p\)) to the specific heat at constant volume (\(C_v\)). For an ideal gas, this ratio is given by

\(\gamma = 1 + (2/\alpha)\),

where α is the degree of freedom.

Since air is a diatomic gas, it has five degrees of freedom (three translational and two rotational). Therefore, α = 5, and substitute this value into the equation

\(\gamma = 1 + (2/\alpha)\) to find \(\gamma = 1 + (2/5) = 1.40\).

When heat is added at constant pressure, and know that \(C_p = C_v + R\), where R is the gas constant. With this information, rearrange the equation to \(C_v = C_p - R\).

To determine the temperature increase\(\Delta T_v\) at constant volume, need to use the relationship \(\Delta Q = C_v\Delta T_v\), where ΔQ represents the amount of heat added. Since the same amount of heat is added in both cases and can equate the heat equations:

\(C_p\Delta T_p = C_v\Delta T_v\).

Using the known values,

\(C_p(100) = (C_p - R)\Delta T_v\)

By substituting

\(\gamma = C_p/C_v = 1.40\)

solving for \(\Delta T_v\),

\(\Delta T_v = 71.43^0C\)

Therefore, the temperature increase at constant volume is approximate \(71.43^0C\).

To develop a rocket with a burnout velocity of 1000 m/s, the specific impulse (Isp) required needs to be calculated. The exit velocity (Ve or Vj) required for the rocket can be determined using the rocket motor equation. The burn time of the rocket can be found by considering the rocket's weight and acceleration over time.

Additionally, the speed of the rocket, assuming a flight path angle of 45 degrees and considering gravity, can be plotted.

1. Calculating Required Isp:

To calculate the required Isp, we use the rocket motor equation: Ve + (Pe - Pa)AC = (m0 / mf) * g0 * Isp, where Ve is the exit velocity, Pe is the pressure at the exit, Pa is the ambient pressure, AC is the throat cross-sectional area, m0 is the initial total mass (rocket weight + propellant weight), mf is the final total mass (rocket weight), g0 is the acceleration due to gravity, and Isp is the specific impulse.

Since the contribution of the pressure differential is ignored, the equation simplifies to Ve = (m0 / mf) * g0 * Isp.

Given the burnout velocity of 1000 m/s, we can substitute the values and solve for Isp.

2. Determining Exit Velocity:

Using the rocket motor equation and the burnout velocity, we can solve for the exit velocity (Ve). This value represents the speed at which exhaust gases leave the rocket nozzle.

3. Plotting Rocket Acceleration and Weight:

To plot the rocket acceleration as a function of time, we need to consider the mass of the rocket over time. Initially, the rocket weight is the sum of the rocket weight (300 kg) and propellant weight (800 kg). As the propellant burns, the rocket weight decreases, resulting in a changing acceleration.

4. Calculating Burn Time:

The burn time of the rocket can be determined by dividing the propellant weight (800 kg) by the propellant consumption rate, which is the mass flow rate of the propellant.

5. Plotting Rocket Speed:

Assuming a flight path angle of 45 degrees and neglecting gravity, the rocket's speed can be plotted over time. This plot represents the rocket's horizontal velocity.

6. Considering Gravity:

To plot the rocket's speed while considering gravity, we need to account for the vertical acceleration due to gravity. By considering the rocket's horizontal and vertical velocities, we can determine the overall speed of the rocket.

By following these steps, the required Isp, exit velocity, burn time, and velocity plots can be determined for the given rocket scenario.

Mount Rainier National Park is located in the Cascade Range of Washington state, and two important geologic forces at work in this area are volcanic activity and glaciers.

Volcanic activity has played a major role in shaping the landscape of Mount Rainier National Park. The mountain is a stratovolcano, which means that it is composed of layers of volcanic ash, rock, and lava flows. Over time, eruptions have built up the mountain and created the characteristic cone shape that we see today. Mount Rainier is still an active volcano, with the last eruption occurring in the mid-1800s. Volcanic activity in the area can cause earthquakes, landslides, and other hazards.

Glaciers have also had a significant impact on the landscape of Mount Rainier National Park. The park is home to the largest glacier system in the contiguous United States, with over 25 named glaciers covering the mountain. These glaciers are formed by snowfall that accumulates over time and compacts into ice. As the ice moves down the mountain, it can carve out valleys and create features such as moraines, cirques, and U-shaped valleys. Glaciers also play an important role in shaping the hydrology of the region, as they melt and feed into streams and rivers.
