(A) For the system consisting of the two blocks, the change in the kinetic energy of the system is equal to work done by gravity on the system.

(D) For the system consisting of the two blocks, the pulley and the Earth, the change in the total mechanical energy of the system is zero.

The total initial mechanical energy of the two block system is calculated as follows;

\(m_1gh_1 + \frac{1}{2} m_1v_1_i^2 = m_2gh_2 + \frac{1}{2} m_2v_2_i^2\\\\m_1gh_1 + 0 = m_2gh_2 + 0\\\\m_1gh_1 = m_2gh_2\\\\m_1gh_1 - m_2gh_2 = 0\)

When the block m2 reaches the ground the block m1 attains maximum height and the total mechanical energy at this point is given as;

\(m_1g(h_1 + h_2) + K.E_1 = \frac{1}{2}m_2v_{max}^2 + P.E_2\\\\m_1g(h_1 + h_2 ) -PE_2 = \frac{1}{2}m_2v_{max}^2 - K.E_1\\\\m_1g(h_1 + h_2 ) - 0= \frac{1}{2}m_2v_{max}^2 - 0\\\\m_1g(h_1 + h_2 ) = \frac{1}{2}m_2v_{max}^2\\\\W = \frac{1}{2}m_2v_{max}^2\)

Thus, we can conclude the following before the block m2 reaches the ground;

When shooting a bow and arrow, the archer pulls back the string and flexes the bow, storing potential energy.

Potential energy is the energy stored in an object due to its position or configuration. This type of energy is the stored energy of an object, which can be released and transformed into other forms of energy, such as kinetic energy. Potential energy is associated with forces such as gravity, electrical, and chemical, which can cause a change in an object’s energy state. Examples of potential energy include a stretched bow and arrow, a roller coaster at the top of a hill, and a compressed spring.

This potential energy is then transferred to the arrow in the form of kinetic energy. The arrow is then put in motion by the archer and due to the force of the bowstring, work is done in the form of acceleration. The arrow is then released and the kinetic energy propels it towards the target.

The altimeter setting at an elevation of 6,500 feet above mean sea level (MSL) is currently 30.42 inches of mercury (Hg). The pressure altitude would be approximately 6,064 feet (1,848 meters) high.

Let's break it down below:In aviation, altimeters measure the height of an aircraft in the atmosphere. The altimeter uses the principle of air pressure. An aircraft altimeter measures air pressure, not altitude. Because air pressure decreases as altitude increases, the instrument's primary function is to measure the pressure of the outside atmosphere and convert it into an altitude reading.

An altimeter setting is the atmospheric pressure measurement for the location of the airport or airfield.The pressure altitude is the altitude indicated by the altimeter when the altimeter setting window is adjusted to 29.92 inches Hg. The pressure altitude is the altitude that an airplane's altimeter would indicate if the aircraft were in standard atmospheric conditions.

Standard conditions are assumed to be a temperature of 59°F and an atmospheric pressure of 29.92 inches Hg at sea level.The pressure altitude is determined by adjusting the altimeter setting to the current barometric pressure and then reading the altimeter's indicated altitude.

As a result, knowing the current altimeter setting is critical when computing pressure altitude. The formula for calculating pressure altitude is as follows:

Pressure altitude = (29.92 – Current Altimeter Setting) x 1000 + Indicated AltitudeIn this case, if the altitude is 6,500 feet MSL, and the current altimeter setting is 30.42 inches Hg, we have:

Pressure altitude = (29.92 – 30.42) x 1000 + 6,500

Pressure altitude = (-0.5) x 1000 + 6,500

Pressure altitude = -500 + 6,500

Pressure altitude = 6,000 feet

Therefore, the pressure altitude would be approximately 6,000 feet or 1,828 meters high.

Explanation:

Given that,

Initial velocity, u = 0

Final velocity, v = 2 m/s

Time, t = 20 s

We need to find the acceleration of the swimmer. The acceleration of an object is equal to the change in velocity per unit time. It can be given by :

\(a=\dfrac{v-u}{t}\\\\a=\dfrac{2\ m/s}{20\ s}\\\\a=0.1\ m/s^2\)

In a space with hyperbolic geometry, the behavior of parallel lines differs from that of Euclidean geometry.

In hyperbolic space, parallel lines diverge from each other as they extend further.If two initially parallel flashlight beams traverse billions of light-years of space in a hyperbolic geometry, they will gradually diverge from each other. The divergence between the beams will increase as they travel a greater distance.

This phenomenon is a consequence of the non-Euclidean geometry of space. In hyperbolic space, the curvature causes parallel lines to "spread out" or diverge. The extent of the divergence will depend on the specific curvature of the space and the distance traveled.

The balloon carries approximately 3.23 x 10^13 excess electrons.

To determine the number of excess electrons on the balloon, we need to use the elemental charge and the charge on the balloon.

The elementary charge, denoted e, is the charge carried by a single electron and has a magnitude of approximately 1.6 x 10^-19 coulombs.

The charge on the balloon is given as -5.16 nC (a negative charge indicates an excess of electrons).

To calculate the number of excess electrons, we can divide the charge on the balloon by the elementary charge:

Number of excess electrons = (balloon charge) / (elemental charge)

Number of excess electrons = (-5.16 nC) / (1.6 x 10^-19 C)

The value that represents the mass of block C that would keep crate D in equilibrium is 196.2 kg (Option D).

To determine of value that represents the mass of block C that would keep crate D in equilibrium, ee can begin by determining the tension in the ropes. Since the crate is held in a certain location by two blocks, the tension in the ropes should be equal. We can use this fact to calculate the tension in the ropes by assuming that they have the same magnitude.

In this case, let T be the tension in each rope segment. The forces acting on the system can be represented in the following free-body diagram:

For the x-direction: T sin 30° = T sin 60° + µg = 0

where µ is the coefficient of friction and g is the acceleration due to gravity. Since the pulleys are frictionless, µ = 0. Therefore, we can simplify the equation as follows:

T sin 30° = T sin 60°

Dividing both sides by T:

sin 30° = sin 60°/2

This gives us: T = (2/√3) mg where m is the total mass of the system and g is the acceleration due to gravity.

Substituting the given values, we obtain:

T = (2/√3) × 150 × 9.81 ≈ 1962 N

Next, we can use the law of the lever to calculate the mass of block C required to keep the crate in equilibrium. According to this law, the sum of the moments acting on the system must be zero. We can choose the point where the ring is attached to the rope as the pivot. This gives us the following equation:

(135 kg)(9.81 m/s²)(3 m) + (mC)(9.81 m/s²)(6 m) - (150 kg)(9.81 m/s²)(4.5 m) - (1962 N)(3 m) = 0

Simplifying: (135)(3) + (6mC) - (150)(4.5) - (1962)(3) = 0

Rearranging: 6mC = 150(4.5) + 1962 - 135(3)

6mC = 2127

mC ≈ 196.2 kg

Therefore, the value that represents the mass of block C required to keep crate D in equilibrium is approximately 196.2 kg. Thus, the correct option is D.

The given figure illustrates a mass m attached to a spring that stretches linearly. The mass is in equilibrium position as shown. The mass is displaced to position x1 and released. The mass will oscillate between x1 and the equilibrium position as shown.

The mass experiences its maximum upward velocity at its equilibrium position because the acceleration is zero at that point. Since the mass oscillates back and forth, it will continue moving until it reaches position x2 on the opposite side. At this point, the velocity of the mass is zero and the acceleration is maximum because the restoring force is maximum. Thus, the mass experiences its maximum upward velocity at the equilibrium position.

In summary, the mass experiences its maximum upward velocity at its equilibrium position. The mass oscillates between the initial position and the equilibrium position and then to the opposite end of the equilibrium position (x2) with zero velocity before returning.

Answer:

Once you have drawn the free-body diagram, you can use vector addition to find the net force acting on the object. We will consider three cases as we explore this idea:

Case 1: All forces lie on the same line.

If all of the forces lie on the same line (pointing left and right only, or up and down only, for example), determining the net force is as straightforward as adding the magnitudes of the forces in the positive direction, and subtracting off the magnitudes of the forces in the negative direction. (If two forces are equal and opposite, as is the case with the book resting on the table, the net force = 0)

Example: Consider a 1-kg ball falling due to gravity, experiencing an air resistance force of 5 N. There is a downward force on it due to gravity of 1 kg × 9.8 m/s2 = 9.8 N, and an upward force of 5 N. If we use the convention that up is positive, then the net force is 5 N - 9.8 N = -4.8 N, indicating a net force of 4.8 N in the downward direction.

Case 2: All forces lie on perpendicular axes and add to 0 along one axis.

In this case, due to forces adding to 0 in one direction, we only need to focus on the perpendicular direction when determining the net force. (Though knowledge that the forces in the first direction add to 0 can sometimes give us information about the forces in the perpendicular direction, such as when determining frictional forces in terms of the normal force magnitude.)

Example: A 0.25-kg toy car is pushed across the floor with a 3-N force acting to the right. A 2-N force of friction acts to oppose this motion. Note that gravity also acts downward on this car with a force of 0.25 kg × 9.8 m/s2= 2.45 N, and a normal force acts upward, also with 2.45 N. (How do we know this? Because there is no change in motion in the vertical direction as the car is pushed across the floor, hence the net force in the vertical direction must be 0.) This makes everything simplify to the one-dimensional case because the only forces that don’t cancel out are all along one direction. The net force on the car is then 3 N - 2 N = 1 N to the right.

Case 3: All forces are not confined to a line and do not lie on perpendicular axes.

If we know what direction the acceleration will be in, we will choose a coordinate system where that direction lies on the positive x-axis or the positive y-axis. From there, we break each force vector into x- and y-components. Since motion in one direction is constant, the sum of the forces in that direction must be 0. The forces in the other direction are then the only contributors to the net force and this case has reduced to Case 2.

If we do not know what direction the acceleration will be in, we can choose any Cartesian coordinate system, though it is usually most convenient to choose one in which one or more of the forces lie on an axis. Break each force vector into x- and y-components. Determine the net force in the x direction and the net force in the y direction separately. The result gives the x- and y-coordinates of the net force.

Example: A 0.25-kg car rolls without friction down a 30-degree incline due to gravity.

We will use a coordinate system aligned with the ramp as shown. The free-body diagram consists of gravity acting straight down and the normal force acting perpendicular to the surface.

We must break the gravitational force in to x- and y-components, which gives:

F_{gx} = F_g\sin(\theta)\\ F_{gy} = F_g\cos(\theta)F

(Note: This equation allows us to determine the magnitude of the normal force.)

Sir Isaac Newton organized the visible colors into a chart known as the color spectrum or Newton's color wheel.

Newton conducted experiments with light and prisms in the 17th century, leading to his groundbreaking work on the nature of light and color. He observed that when white light passes through a prism, it separates into a continuous band of colors. This band of colors, arranged in a specific order, became known as the color spectrum. Newton's color spectrum consists of the colors red, orange, yellow, green, blue, indigo, and violet. He arranged these colors in a circular shape, resembling a wheel, where each color transitions smoothly into the next. This representation of colors was a significant contribution to our understanding of the visible light spectrum and paved the way for further investigations into the properties of light and color by subsequent scientists.

With Ohm's Law

The series is equivalent of a single resistor of Resistance \(2.2\cdot 10^3+6.8\cdot 10^3 \Omega = 9.0 k\Omega\). By Ohm's first Law (\(V=Ri\)) the current flowing through the resistor is \(9V = 9*10^3\Omega i \rightarrow i=1mA\). At this point, the drop across the first resistor is, again by Ohm's law\(V = 2.2 \cdot 10^3 \Omega \cdot 1\cdot 10^{-3} A = 2.2V\)
