Work done by friction and air resistance -780,000 Joules. Since the work done by the combined forces of friction and air resistance is negative, this means that these forces are doing negative work on the car, which means that they are slowing the car down.

The work done on the car by the force propelling it up the mountain road is given by W = Fd, where F is the force and d is the distance over which the force is applied. Since the force is nonconservative, the work it does on the car is not equal to the change in the car's kinetic energy. Instead, the work done by the force propelling the car is equal to the change in the car's potential energy plus the work done by the nonconservative forces of friction and air resistance.

To find the work done by the combined forces of friction and air resistance, we can use the following equation:

Work done by friction and air resistance = change in kinetic energy - change in potential energy

We can find the change in the car's kinetic energy by subtracting its initial kinetic energy (0 Joules, since it starts from rest) from its final kinetic energy. The final kinetic energy of the car is given by

[tex]KE = \frac{1}{2} mv^2[/tex]

where m is the mass of the car and v is its speed. Plugging in the values, we get:

[tex]KE = (1/2)(1.50 * 103 kg)(27.0 m/s)^2 = 2.16 * 105[/tex] joule

The change in the car's potential energy can be found by subtracting its initial potential energy (which is 0 Joules at sea level) from its final potential energy. The final potential energy of the car is given by

PE = mgh,

where m is the mass of the car, g is the acceleration due to gravity, and h is the height of the car above the ground. Plugging in the values, we get:

PE = (1.50 x 103 kg)(9.8 m/s²)(2.00 x 102 m) = 2.94 x 105 Joules

Substituting these values into the equation above, we get:

Work done by friction and air resistance = (2.16 x 105 Joules) - (2.94 x 105 Joules) = -780,000 Joules

a) It will travel 4.082 seconds before the car is alongside the truck

b)The car be moving at a speed of 12.246 m/s relative to the truck when they are side by side

c)The distance travelled by car is 106.64 m

d)The distance travelled by truck is 81.64 m

What is meant by relative motion?

The motion of one body when compared to another which is considered to be fixed is known as relative motion.

Initial velocity of the car ,u₁ = 20.0 m/s

Initial velocity of the truck ,u₂ = 20.0 m/s

Initially the distance between the truck and the car, d = 25 m

acceleration of the car,a₁ =  3.0 m/s²

a)  For the car to reach the truck in a time interval( t ) , the distance travelled by car in that time( s₁ ) should be 25m more than the distance travelled by the truck in the same time interval( s₂ )

⇒ s₁ = 25 + s₂                      

    u₁t+ 1/2a₁t² = 25 + u₂t +0        ( by eqn of motion , s = ut + 1/2at²)

    20t + 1/2 * 3 * t² = 25 + 20t

     1/2 * 3 * t² = 25

     t² = 50/3

   t = √50/3

   t = 4.082 s

Therfore, It will travel 4.082 seconds before the car is alongside the truck

b)   Time taken for them to reach side by side ,t = 4.082 s

     velocity of car at that instance , v₁ =u₁ +  a₁t

                                                          v₁ = 20 + 3 (4.082)

                                                              = 20 + 12.246

   ∴ v₁ =32.246 m/s

    relative velocity to the truck ,v₁₂ = v₁ - u₁  

                                                         = 32.246- 20

                                                         = 12.246 m/s

Therefore the car be moving at a speed of 12.246 m/s relative to the truck when they are side by side?

c)  Distance travelled by car , s₁ = u₁t + 1/2a₁t²

                                                  =  20 (4.082) + 1/2 * 3 * (4.082)²

                                                   = 81.64 + 25

                                                    =106.64 m

Therfore the distance travelled by car is 106.64 m

d) Distance travelled by  the truck , s₂ = u₂t

                                                              = 20(4.082)

                                                             = 81.64 m

Therfore the distance travelled by truck is 81.64 m

Energy (E) is related to wavelength (λ) and frequency (ν) according to the equation E=hν, where h is Planck’s constant (6.626 × 10-34 J-s).

Wavelength is the distance between two successive peaks or troughs of a wave, such as light, sound, or other forms of energy. It is measured in meters or nanometers and is related to the frequency of the wave, as the frequency is inversely proportional to the wavelength. Wavelength can also be used to describe the physical size of an object, such as a particle or cell.
The equation for calculating wavelength (λ) is λ=c/ν, where c is the speed of light (3.0 × 10⁸ m/s). The equation for calculating frequency (ν) is ν=c/λ. Therefore, the formulas for calculating energy wavelength and frequency are:

Answer:

The impulse applied to the athlete as she slows down is 28 N*s.

Explanation:

To calculate the impulse applied to the athlete as she slows down, we can use the equation:

impulse = force * time

Since the force applied to the athlete is equal to her mass times her acceleration, we can also express the impulse as:

impulse = mass * (vf - vi) / time

Plugging in the values given in the question, we get:

impulse = 71 kg * (4 m/s - 10 m/s) / time

Solving for impulse, we get:

impulse = 28 N*s

Therefore, the impulse applied to the athlete as she slows down is 28 N*s.

The separation of the plates in this parallel-plate capacitor is approximately 6.49 micrometers.

The separation of the plates in a parallel-plate capacitor can be calculated using the equation:

d = ε0 * ∆V/σ

where d is the separation of the plates, ε0 is the electric constant (also known as the permittivity of free space), ∆V is the potential difference between the plates, and σ is the surface charge density on the plates.

In this case, the potential difference between the plates is given as v = 6.0 V, and the surface charge density on the plates is given as σ = 7.0 nC/m^2. Plugging these values into the equation above, we get:

d = (8.85 x 10^-12 C^2/N*m^2) * (6.0 V) / (7.0 nC/m^2)

This simplifies to:

When the ice skater pulls her arms in close to her body, her angular momentum remains the same because it is a conserved quantity. When the ice skater pulls her arms in, her moment of inertia decreases. When the ice skater pulls her arms in, her angular speed increases. When the ice skater pulls her arms in, her rotational kinetic energy increases.

When the ice skater pulls her arms in close to her body, her angular momentum remains the same because it is a conserved quantity. Angular momentum is defined as the product of the moment of inertia and the angular velocity of an object, and it is conserved as long as there is no external torque acting on the object. In this case, since the ice skater is not being acted upon by an external torque, her angular momentum will not change when she pulls her arms in.

When the ice skater pulls her arms in, her moment of inertia decreases. The moment of inertia of an object is a measure of its resistance to changes in its rotational motion, and it is directly proportional to the mass of the object and the distance of the mass from the axis of rotation. When the ice skater pulls her arms in, she reduces the distance of her mass from the axis of rotation, which decreases her moment of inertia.

When the ice skater pulls her arms in, her angular speed increases. This is because the decrease in her moment of inertia leads to an increase in her angular velocity, according to the equation:

ω = L / I

where ω is the angular velocity, L is the angular momentum, and I is the moment of inertia.

When the ice skater pulls her arms in, her rotational kinetic energy increases. This is because the rotational kinetic energy of an object is directly proportional to its moment of inertia and its angular velocity squared, according to the equation:

Krot = (1/2) * I * ω^2

Therefore, when the ice skater's moment of inertia decreases and her angular velocity increases, her rotational kinetic energy will also increase.

The sign of q, or the heat transfer, for the process of compressing the air in a bicycle pump, is positive. This means that heat is being transferred into the system, in this case, the air in the pump.

When a gas is compressed, the molecules collide more frequently and with greater force, which increases the temperature of the gas. This increase in temperature is due to the transfer of heat from the surroundings (in this case, the body of the pump) into the gas.

The sign of q can be determined using the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

If heat is added to the system, q is positive, and if heat is removed from the system, q is negative. In the case of compressing the air in a bicycle pump, the internal energy of the system (the air in the pump) increases, which means that q is positive.
