The combination of frequencies that produce the lowest beat frequency is 10 Hz and 15 Hz. The correct option is C.

To determine the beat frequency, we subtract one frequency from the other and take the absolute value. The beat frequency is the difference between the frequencies involved in the interference pattern created by two sound waves.

Let's analyze each option:

A. 500 Hz and 501 Hz: The beat frequency would be 501 Hz - 500 Hz = 1 Hz.

B. 10 Hz and 20 Hz: The beat frequency would be 20 Hz - 10 Hz = 10 Hz.

C. 10 Hz and 15 Hz: The beat frequency would be 15 Hz - 10 Hz = 5 Hz.

D. 500 Hz and 600 Hz: The beat frequency would be 600 Hz - 500 Hz = 100 Hz.

Therefore, option C (10 Hz and 15 Hz) produces the lowest beat frequency of 5 Hz compared to the other options.

We can use a free-body diagram and torque calculations to determine that when one person applies an upward force of 60 N to one end of a uniform wooden board that is 3.00 m long and weighs 160 N, the other person will lift at the opposite end of the board.

We need to first draw a free-body diagram of the wooden board. A free-body diagram is a diagram that shows all the external forces acting on an object. In this case, we have a uniform wooden board that is being carried by two people, and we want to know at what point the other person lifts when one person applies an upward force of 60 N at one end.

The free-body diagram of the wooden board would show the weight of the board acting downwards at its center, which is 80 N (half of 160 N). The upward force of 60 N would be acting at one end of the board. The reaction force from the other person would be acting upwards at some point along the board, and we want to find out where that point is.

To find the point at which the other person lifts, we need to consider the torque acting on the board. Torque is a measure of the twisting force that causes rotation, and it is calculated as the product of the force and the perpendicular distance from the force to the point about which the torque is being calculated. In this case, the point about which the torque is being calculated is the center of the board.

The torque due to the weight of the board is zero, since the weight is acting at the center of the board. The torque due to the upward force of 60 N is 1.5 Nm, since the perpendicular distance from the force to the center of the board is 1.5 m (half of 3.00 m). The torque due to the reaction force from the other person is also 1.5 Nm, since it is also acting at a distance of 1.5 m from the center of the board.

Since the torques due to the upward force and the reaction force are equal, we can conclude that the other person is lifting the board at a point that is exactly opposite to the point where the 60 N force is being applied. In other words, if one person is applying the 60 N force at the left end of the board, the other person is lifting at the right end of the board.

This is because the torques due to the upward force and the reaction force are equal, and the point at which the other person lifts is exactly opposite to the point where the 60 N force is being applied.

The lens for the slide projector needs a focal length of approximately -20.15 mm, and it should be placed approximately 1.1063 meters in front of the slide.

The focal length of the lens required for the slide projector and the distance at which the lens should be placed from the slide, use lens formula and magnification formula.

The lens formula is given by:1/f = 1/v - 1/u

Where:

f is focal length of the lens,

v is image distance,

u is object distance.

Given screen distance (v) is 270 cm,image height (v') is 90 cm, object height (u') is 2.0 cm,use the magnification formula to relate magnification factor (m):m = v'/u' = -v/u

Since slide is placed on object side of lens, the magnification factor is negative.

Calculate the focal length (f) using lens formula:

1/f=1/v-1/u

1/f=1/270-1/2

1/f=(2-270)/(270*2)

1/f=-268/540

f=-540/268

f≈-2.015 cm(approximately -20.15mm)

The negative sign indicates that the lens is a diverging lens.

1/f=1/v - 1/u

1/u=1/f+1/v

1/u=1/(-20.15 mm)+1/270 cm

u=(270 * 20.15)/(-49.26)

u=-110.63 cm

The negative sign indicates that the lens should be placed 1.1063 meters in front of the slide.

As you continue to apply heat to a block of ice at -10°C, two main events occur: the temperature of the ice increases until it reaches 0°C, and then the ice begins to melt.

Initially, when you apply heat to the block of ice at -10°C, the temperature of the ice increases. The heat energy is used to increase the kinetic energy of the ice molecules, causing the temperature to rise. Once the ice reaches 0°C, any additional heat applied will not increase the temperature further. Instead, the heat energy will be used to break the bonds between the ice molecules, leading to a phase change from solid ice to liquid water. This process is called melting. During the melting process, the temperature remains constant at 0°C.

Applying heat to a block of ice at -10°C results in a temperature increase until it reaches 0°C, followed by the melting of the ice while maintaining a constant temperature.

Answer: Magnitude of the force exerted on the egg by the ground is 9.2N

Explanation:

Given the following :

Mass of egg (m) = 150g = 0.15kg

Height(h) from which egg is dropped = 3m

velocity of egg before hitting the ground (u) = 4.4m/s

Final velocity of egg (V) = 0

Time taken (t) = 0.072s

Magnitude of the force exerted on the egg by the ground can be found by applying Newton's 2nd law:

Momentum = mass × velocity

From Newton's second law:

Force = mass × change in Velocity with time ;

That is

F = m * ΔV / t

Inputting our values

F = 0.15 * (4.4 - 0) / 0.072

F = 0.15 × (4.4 / 0.072)

F = 0.15 × 61.11

F = 9.16N

F = 9.2N

The microscope went approximately 2.33 meters down the well.

To determine the distance the microscope traveled down the well, we need to use the work-energy principle. The work done on an object is equal to the change in its potential energy.

Given that 8.0 J of work was done, we can equate this to the change in potential energy:

Work done = Change in potential energy

The potential energy of an object near the Earth's surface is given by the equation:

Potential energy = mass × acceleration due to gravity × height

Rearranging the equation, we can solve for the height:

Height = Work done / (mass × acceleration due to gravity)

Plugging in the given values:

Work done = 8.0 J

Mass = 343 g = 0.343 kg (converting to kilograms)

Acceleration due to gravity = 9.8 m/s² (approximately)

Height = 8.0 J / (0.343 kg × 9.8 m/s²)

Calculating the height:

Height ≈ 2.33 meters

The velocity of the water in the pipe, when it tapers down to a cross-sectional area of 0.751, is approximately 7.989 m/s.

To calculate the velocity of water in the pipe when the cross-sectional area tapers down to 0.751, we can use the principle of continuity. According to the principle of continuity, the product of the cross-sectional area and velocity of a fluid remains constant.

Cross-sectional area 1 = 1

Velocity 1 = 6 m/s

Cross-sectional area 2 = 0.751

Using the principle of continuity, we can write:

Cross-sectional area 1 * Velocity 1 = Cross-sectional area 2 * Velocity 2

Plugging in the given values, we have: 1 * 6 = 0.751 * Velocity 2

Simplifying the equation, we get:

Velocity 2 = (1 * 6) / 0.751

Velocity 2 ≈ 7.989 m/s

Therefore, the velocity of the water in the pipe, when it tapers down to a cross-sectional area of 0.751, is approximately 7.989 m/s.

Answer:

It is not still true that the average velocity of the particle is equal to half the sum of the initial and final velocities when the acceleration of the particle is not constant

Explanation:

The motion of a particle under constant acceleration, 'a', is be given by the following kinematic equations;

v² = u² + 2·a·s

v = u + a·t

Where;

v = The final velocity of the particle

u = The initial velocity of the particle

a = The acceleration of the particle

s = The distance through which the particle travels

t = The time of motion of the particle

By simplifying the above equation, we have;

v² - u² = 2·a·s

(v² - u²)/(2·a) = s

(v - u) × (v + u)/(2 × a) = s

((v - u)/a) × ((v + u)/2) = s

From v = u + a·t, we have;

t = (v - u)/a

∴ ((v - u)/a) × ((v + u)/2) = t × ((v + u)/2) = s

∴ ((v + u)/2) = s/t

The average velocity = (Total distance traveled by the particle) ÷ (The time of travel of the particle)

∴ The average velocity = s/t = ((v + u)/2) = Half the sum of the initial and final velocity

However, it is not still true that the average velocity of the particle is equal to half the sum of the initial and final velocities when the acceleration of the particle, 'a', is not constant, as the velocity time graph is no longer a straight line graph and the distance traveled by the particle, 's', which is the area under the velocity time graph, 'A', (given by the sum of area of the triangle and the rectangle given by the area under straight line graph for constant velocity) cannot be given directly by the product of the time and the average velocity.
