A) Work done = Fd cosθ = 71.392 × 9.2 × cos32 = 557 J

B) the increase in thermal energy of the block-floor system = 557J since the frictional force is equal to the force in the horizontal direction.

The force acting on the body has vertical and horizontal component

the vertical component of the acting on the body = F sinθ

the horizontal component of the force acting on the block = F cosθ

since the block is moving with constant speed

then the frictional force = F cosθ in the opposite direction

μk = frictional force / force of normal

force of  normal = mg + f sinθ

μk ( mg + Fsinθ) = F cosθ

μkmg = F cosθ - μk Fsinθ = F ( cos 32 - 0.2sin32) = 0.2 × 9.81 × 27

F (0.848 - 0.10598) = 52.974

OPTION  B IS THE ANSWER

Answer:

The real answer is A 2023 answer -_-

Explanation:

Hello!

This is an example of an inelastic collision, where the two objects "stick" to each other after their collision. (The Goalkeeper CATCHES the puck).

We can write out the conservation of momentum formula:

m1vi + m2vi = m1vf + m2vf

Let:

m1 = mass of puck

m2 = mass of the goalkeeper

We know that the initial velocity of the goalkeeper is 0, so:

m1vi + m2(0) = m1vf + m2vf

m1vi = m1vf + m2vf

The final velocities will be the same, so:

m1vi = (m1 + m2)vf

Plug in the given values:

(0.16)(40)/ (0.16 + 120) = vf ≈ 0.0533 m/s

Using the equation for momentum:

p = mv

The object with the LARGER mass will have the greater momentum. Thus, the Goalkeeper has the largest momentum as p = mv; a greater mass correlates to a greater momentum since the velocity is the same between the two objects. The puck would have a momentum of p = (.16)(0.0533) = 0.008528 kgm/s, whereas the goalkeeper would have a momentum of

p =  (120)(0.0533) = 6.396 kgm/s.

In the open ocean, the relationship between wave height and occurrence of larger waves can be described probabilistically. While the exact value may vary depending on several factors, it is often estimated that approximately 1 wave in every 100 will be three times as high as the average wave height.

Wave heights in the open ocean are influenced by various factors, including wind speed, duration, and fetch (the distance over which the wind blows). These factors determine the energy transferred to the water surface, resulting in the formation of waves. As waves propagate across the ocean, they undergo complex interactions, resulting in a distribution of wave heights.

The average wave height refers to the statistical mean of the wave heights observed over a given period. However, due to the randomness and variability of wave generation and propagation, it is expected that occasionally larger waves will occur. These larger waves can be significantly higher than the average, reaching up to three times its height.

It's important to note that this estimation may not hold true in all circumstances and locations. Wave conditions can be highly variable and depend on regional and seasonal factors. Therefore, wave forecasting models and empirical data collected specifically for a particular region can provide more accurate estimates of the occurrence of waves of a certain height relative to the average.

Explanation:

Physical weathering is breaking down rocks, but it doesn't change what the rock is made out of.

The physical weathering is The breakdown of rocks into smaller rocks, therefore the correct answer is option B

Physical weathering, often referred to as mechanical weathering, is the process that fractures rocks without altering their chemical makeup. The following instances show physical weathering: water flowing quickly. For brief periods of time, swiftly rushing water has the ability to raise boulders out of the streambed.

Physical weathering can be divided into two categories: When water seeps into cracks over time, freezes, and then expands, it undergoes a process called freeze-thaw, which finally breaks the rock. Exfoliation happens when fissures appear parallel to the surface of the ground as a result of the pressure drop during uplift and erosion.

The work required to compress 5.00 mol of air at 20.0°C and 1.00 atm to one-tenth of the original volume by an isothermal process is approximately 3.4306 * 10^4 J.

To calculate the work required to compress the air by an isothermal process, we can use the formula:

W = -nRT ln(Vf/Vi)

where:

W is the work done on the system,

n is the number of moles of gas (5.00 mol in this case),

R is the ideal gas constant (8.314 J/(mol·K)),

T is the temperature in Kelvin (20.0°C = 20.0 + 273.15 K),

Vi is the initial volume,

Vf is the final volume.

Given:

Initial volume, Vi = V

Final volume, Vf = 1/10 * Vi = 1/10 * V

Substituting the given values into the equation, we have:

W = -nRT ln(Vf/Vi)

W = -(5.00 mol)(8.314 J/(mol·K))(20.0 + 273.15 K) ln((1/10 * V)/V)

Simplifying further:

W = -5.00 mol * 8.314 J/(mol·K) * 293.15 K * ln(1/10)

W = -5.00 * 8.314 * 293.15 * ln(0.1)

Using ln(0.1) ≈ -2.3026, we can calculate the work:

W ≈ -5.00 * 8.314 * 293.15 * (-2.3026)

W ≈ 3.4306 * 10^4 J

Therefore, the work required to compress 5.00 mol of air at 20.0°C and 1.00 atm to one-tenth of the original volume by an isothermal process is approximately 3.4306 * 10^4 J.

It took 2.04 seconds for the rock to reach the ground, after it was thrown vertically downward at a velocity of 15.0 m/s.

What is velocity?

Velocity is a vector quantity that describes the rate of change of an object's position in a specific direction. It is defined as the distance an object travels per unit of time. The standard unit of velocity is meters per second (m/s) in the International System of Units (SI).

To determine how long it took for the rock to reach the ground, we can use the equation:

d = v0t + (1/2)gt^2

Where d is the distance traveled, v0 is the initial velocity (which is zero for a rock that is thrown vertically downward), t is the time, and g is the acceleration due to gravity (approximately 9.8 m/s^2).

Since we know the distance traveled and the final velocity of the rock, we can rearrange the equation and solve for t:

t = (2d / g)^1/2

Plugging in the given values:

t = (2 * 10 m / 9.8 m/s^2)^1/2 = (2 * 10 / 9.8)^1/2 = 2.04 s

Therefore, it took 2.04 seconds for the rock to reach the ground, after it was thrown vertically downward at a velocity of 15.0 m/s.

The magnitude of the point charge that creates an electric field of 80,000 N/C at a distance of 0.285 m is approximately 2.057 x 10⁻⁶ C.

To determine the magnitude of the point charge that creates an electric field of 80,000 N/C at a distance of 0.285 m, we can use the formula for the electric field strength due to a point charge.

The formula is given by: E = k x (q / r²)

where:
- E is the electric field strength,
- k is the electrostatic constant (k = 8.99 x 10⁹ N m²/C²),
- q is the magnitude of the point charge, and
- r is the distance from the point charge.

In this case, we are given that the electric field strength is 80,000 N/C and the distance is 0.285 m.

Plugging these values into the formula, we can solve for the magnitude of the point charge (q):

80,000 N/C = (8.99 x 10⁹ N m²/C²) x (q / (0.285 m)²)

To isolate q, we can multiply both sides of the equation by (0.285 m)² and divide by 8.99 x 10⁹ N m²/C²:

q = (80,000 N/C) x (0.285 m)² / (8.99 x 10⁹ N m²/C²)

Simplifying this expression, we find:

q ≈ 2.057 x 10⁻⁶ C

So, the magnitude of the point charge that creates an electric field of 80,000 N/C at a distance of 0.285 m is approximately 2.057 x 10⁻⁶ C.
