Answer:

D  All

Explanation:

Mechanical and electromagnetic waves both carry energy. The mechanical wave via the motion/vibration of particles, and the electromagnetic via vibration of the electric and magnetic fields.

We know of interference patterns of light (electromagnetic interference), as well as interference of mechanical waves of water generating typical patterns.

Both, electromagnetic and mechanical waves go through the process of reflection when hitting a barrier (mirror for example in the case of light, and a solid wall for example in the case of water waves.

So the correct answer is "All of the above"

Change in momentum formula

The change in momentum resulting from an external force is called the impulse (I=mv-mvo) and is related to the force applied through the Impulse-Momentum Theorem: I = F tc = mv - mvo . Here F is the external force applied and tc is the amount of time the force is in contact with the object.

The final velocity ( Vf ) of the cart at rest is : 0.5 m/s

Change in momentum of the objects  = m₁ * ΔV = m₂ * ΔV --- ( 1 )

Given that momentum ( p ) = m * v

where ; m₁ = 10 kg , p = 10 kg.m/s , v = ?

calculate for v

v = p/m = 10 kg.m/s / 10 kg

            = 1 m/s

Back to equation ( 1 )

= 10 * ( 1 m/s ) =  20 * ( Vf - )

= 10 = -20 Vf  

therefore Vf ( final velocity of cart at rest ) = 10 / 20

                                                                      = 0.5 m/s

Hence we can conclude that The final velocity ( Vf ) of the cart at rest is : 0.5 m/s

Answer:

a = 0.1 [m/s²]

Explanation:

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

\(v_{f}=v_{o}+a*t\)

Vf = final velocity = 0.8 [m/s]

Vo = initial velocity = 0.3 [m/s]

a = acceleration [m/s²]

t =  time = 5 [s]

\(0.8=0.3+a*t\\0.5 = 5*a\\a = 0.1 [m/s^{2}]\)

The principle of conservation of energy allows to find the result for the mechanical energy of the system is:

Mechanical energy is defined by the sum of the kinetic energy and the potential energies.

            Em = K + U

In the principle of energy conservation, it establishes that energy cannot be created or destroyed, it is only transformed, in the case of no friction, mechanized energy is conserved at all points.

They indicate that the system is rotating, which is why it is subjected to a force that expends its energy in changing the direction of the speed to keep the system in rotation, so the speed of the system remains constant.

          Em = K = ½ I w²

Consequently, using the principle of conservation of energy we can find the result for the mechanical energy of the system is:

I guess A option is correct

If the pendulum illustrated above has a length of 2m and a bob of mass of 0.04 kg. The frequency of oscillation is most nearly is: E.) (√5)/(2π) hz.

The frequency of a simple pendulum is given by:

f = 1/(2π) √(g/L)

where g is the acceleration due to gravity, and L is the length of the pendulum.

In this case, L = 2m and the mass of the bob is 0.04kg. We are given cos(theta) = 0.9, so sin(theta) = √(1 - cos^2(theta)) = 0.4359.

The force of gravity on the bob is given by F = mg, where m is the mass of the bob and g is the acceleration due to gravity. The component of this force acting along the direction of motion is F sin(theta) = mg sin(theta) = 0.04 x 9.8 x 0.4359 = 0.170 N.

Using this force and the length of the pendulum, we can find the acceleration of the bob along the direction of motion:

a = F sin(theta)/m = 0.170/0.04 = 4.25 m/s^2

Substituting this acceleration and the length of the pendulum into the formula for frequency, we get:

f = 1/(2π) √(g/L) = 1/(2π) √(4.25/2) = (√5)/(2π) Hz

Therefore, the answer is E.

Explanation:

If a sunspot were pointed right at Mercury in this way, the planet would become even more mind-bogglingly hot. Sunspots look dark in our visual spectrum, so we might suspect that they are colder (or at least less hot) than the rest of the Sun; but in fact, they are hotter.

When discussing Newton's laws of motion, people most likely use the terms "action" and "reaction" when talking about Newton's third law of motion.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.

In other words, if object A pushes or pulls on object B with a certain force, then object B will push or pull back on object A with an equal and opposite force. This law applies to all types of forces, whether they are contact forces or non-contact forces, such as gravitational or electromagnetic forces.

This law is important in understanding how forces work in the physical world. It helps explain why things don't just keep accelerating indefinitely when a force is applied, and why forces always come in pairs. It also plays a crucial role in understanding the behavior of systems like rockets, airplanes, and cars.

When designing a water rocket made from recycled or readily available materials, the main component is typically a two-liter plastic bottle. The conceptual design options for the water rocket include variations in fins, nose cones, and deployment mechanisms.

The options for the design of a water rocket include variations in fins, nose cones, and deployment mechanisms. Fins are essential for providing stability during flight. Different fin shapes and sizes can affect the rocket's stability and control.

Larger fins generally provide better stability but may increase drag, while smaller fins can reduce stability but improve aerodynamic performance. The choice of fin design depends on the desired trade-off between stability and aerodynamics.

The nose cone design is another important consideration. A pointed nose cone reduces drag and improves aerodynamics, allowing the rocket to reach higher altitudes.

However, a pointed nose cone can be challenging to construct using readily available materials. An alternative option is a rounded nose cone, which is easier to construct but may result in slightly higher drag.

The deployment mechanism refers to the method of releasing a parachute or recovery system to slow down the rocket's descent and ensure a safe landing. The options include a simple nose cone ejection system or a more complex deployment mechanism triggered by pressure, altitude, or time. The choice of deployment mechanism depends on factors such as reliability, simplicity, and the availability of materials for construction.

In the chosen design route, the emphasis is on simplicity, stability, and ease of construction. The rocket design incorporates moderately sized fins for stability and control, a rounded nose cone for ease of construction, and a simple nose cone ejection system for parachute deployment.

This design strikes a balance between stability and aerodynamic performance while utilizing readily available or recycled materials.

To complete a failure mode and effects analysis (FMEA), five aspects of the design should be considered. These aspects can include potential failure points such as fin detachment, parachute failure to deploy, structural integrity of the bottle, leakage of water, and ejection mechanism malfunction.

By identifying these potential failure modes, appropriate design improvements and safety measures can be implemented to mitigate risks.

The height a water rocket can reach is influenced by various physics principles. Factors that affect the flight of the rocket include thrust generated by water expulsion, drag caused by air resistance, weight of the rocket, and the angle of launch.

To optimize the height, the physics data required would include the mass of the rocket, the volume and pressure of the water, the drag coefficient, and the launch angle.

Experimental data can be obtained through launch tests where the rocket's flight parameters are measured using appropriate instruments such as altimeters, accelerometers, and cameras.

By analyzing and correlating the data, the computational model can be refined to predict and optimize the rocket's maximum height.

A sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 L to 15 L. The final pressure is 0.67 atm.

A physics principle states that a gas's volume changes inversely with applied pressure while the gas is kept at a constant temperature. Boyle's law states that in constant temperature the  variation volume of gas is inversely proportional to the applied pressure. According to Boyle's law, a gas's pressure is inversely proportional to its volume while the gas is at constant temperature.  To put it another way, we can argue that volume and pressure are inversely proportional to one another, but only for gases with constant mass and temperature.

The formula is,

P₁ X V₁ = P₂ X V₂

Where,

P₁ is initial pressure = 1 atm

P₂ is final pressure =  ? (Not Known)

V₁ is initial volume  = 10 L

V₂ is final volume = 15 L

Now put the values in the formula,

1 x 10 = P₂ x 15

10 = 15 P₂

P₂ = 0.67

Therefore, the final pressure is 0.67 atm.

Answer:

Effort = 540 Newton

Explanation:

Given the following data;

Load arm = 60 cm

Effort arm = 40 cm

Load = 360 N

Conversion:

100 cm = 1 meters

40 cm = 40/100 = 0.4 meters

60 cm = 60/100 = 0.6 meters

To calculate the effort that Reha should apply to lift Neha, we would use the expression;

Effort * effort arm = load * load arm

Substituting into the expression, we have;

Effort * 0.4 = 360 * 0.6

Effort * 0.4 = 216

Effort = 216/0.4

As the sun climbs to its noontime position, the solar zenith angle decreases and in response the solar flux increases.
Option a is correct.

This phenomenon occurs due to the fact that the angle of incidence between the sun's rays and the Earth's surface becomes more perpendicular as the sun climbs higher in the sky towards its noontime position. This increases the amount of solar radiation that is absorbed by the Earth's surface, resulting in an increase in solar flux. However, it is important to note that this increase in solar flux is not constant throughout the day and can be affected by factors such as cloud cover and atmospheric conditions.

Answer:

the height that the pendulum is released is 0.2305 m

Explanation:

The total mechanical energy of the pendulum is the sum of its potential energy and kinetic energy.

At the maximum velocity (2.1 m/s), the pendulum's kinetic energy is at its maximum, while the potential energy is at its minimum. This occurs when all the potential energy is converted to kinetic energy.

The equation for the conservation of mechanical energy is: E = KE + PE

Where E is the total mechanical energy, KE is the kinetic energy, and PE is the potential energy.

At the highest point (when the pendulum is released), all the energy is in the form of potential energy, and the kinetic energy is zero. Therefore, we have:

E = KE + PE

0.5 * m * v² + m * g * h = 0

Where m is the mass of the pendulum, v is the maximum velocity (2.1 m/s), g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height.

h = -(0.5 * (2.1 m/s)²) / (9.8 m/s²)

h ≈ -0.2305 m

Since height cannot be negative, we disregard the negative sign and take the absolute value:

h ≈ 0.2305 m

Explanation:

The computation of the magnitude of q is shown below;

The electric field at point P because of point charge Q is provided by,

E = 8.6 × 10^-2 N/C

And, the separation between charge Q and P is r = 1.7m

Now According to the Coulomb's law,

E = kQ ÷ r²

The bird with a mass of 26 g perches in the middle of a stretched telephone line. The tension in the wire is 0.12753 N.

To determine the tension when the bird is perching:

Tension is the force that stretches a string or a telephone line. The bird's weight will cause the wire to stretch by a certain amount. The weight of the bird can be calculated as follows:

Weight = mass × gravity

The weight of the bird is:

Weight = 26 g × 9.81 m/s2 = 255.06 g · m/s2 = 0.25506 N

This force will be evenly distributed across the wire, causing it to stretch evenly in all directions.

As a result, the tension in the telephone wire will be the weight of the bird divided by two. This is due to the fact that the weight of the bird is evenly distributed over the length of the wire. The tension formula is given as:

Tension = weight of the bird/2

Tension = 0.25506 N / 2 = 0.12753 N

Therefore, when the bird is perching in the middle of a stretched telephone line, the tension in the wire is 0.12753 N.

To calculate the acceleration of the two-dimensional flow, we need to compute the time derivatives of the velocity components.

The velocity components are:

u = 2ax + 2bxy

v = 2ay + 2byx

Taking the time derivatives of these equations:

du/dt = 2a(dx/dt) + 2b(dy/dt)x + 2b(x(dy/dt) + y(dx/dt))

dv/dt = 2a(dy/dt) + 2b(dx/dt)y + 2b(y(dx/dt) + x(dy/dt))

Simplifying these expressions:

du/dt = 2a(dx/dt) + 4b(dy/dt)x + 2b(dy/dt)y

dv/dt = 2a(dy/dt) + 4b(dx/dt)y + 2b(dx/dt)x
