From the calculation, there is a net force that acts on the car and then the acceleration that is produced by the net force is 0.296 m/s^2.

The term net force refers to the force that is acting on an object that makes it to move. We have to recall that the force of friction is the force the limits the motion of an object. In other words, it is the force of friction that makes a body not to be able to move and this must be overcome by the forward force when it is greater than the friction force.

Now;

Mass of the car = 1352 kg

Forward force = 7820 N

Coefficient of friction = 0.56

Frictional force = μmg

= 0.56 * 1352 kg * 9.8 m/s^2

= 7419.8 N

Net force = Forward force - Frictional force

= 7820 N -  7419.8 N

= 400.2 N

Then;

Net force = ma

m = mass

ANSWER

E. No, since work involves a non-zero displacement

EXPLANATION

Work done on an object is given by,

Where W is work, F is the force applied on the object, d is the displacement of the object and θ is the angle between the applied force and the displacement.

Note that if there's no motion, then d = 0. Because d is multiplying the other variables, if d = 0 then work is zero as well.

Hence, the answer is option E.

The structure indicated by the number 2 in the figure is the mitochondrion, and its functional significance is energy production through cellular respiration.

The mitochondrion is an organelle found in most eukaryotic cells, responsible for producing energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. It is often referred to as the "powerhouse" of the cell due to its crucial role in energy production.

Mitochondria have a unique double membrane structure. The outer membrane acts as a protective barrier, while the inner membrane is highly folded into structures known as cristae. These folds greatly increase the surface area available for chemical reactions and the production of ATP.The functional significance of the mitochondrion lies in its ability to generate ATP, which is the main energy currency of the cell. Through the process of cellular respiration, the mitochondria break down organic molecules, such as glucose, to extract energy and convert it into ATP. This energy is then utilized by the cell to perform various functions, including growth, movement, and maintaining cellular processes.

In addition to energy production, mitochondria also play a role in other cellular processes, such as calcium signaling, metabolism regulation, and apoptosis (programmed cell death). Their involvement in these functions underscores their importance in overall cellular health and homeostasis.In summary, the mitochondrion is a specialized organelle responsible for energy production through cellular respiration. Its structural features and unique functions make it vital for providing the necessary energy for cellular processes.

Therefore, option c) is the correct statement since the image produced by a convex mirror is always smaller than the object and hence larger than one produced by a plane mirror in its place.

A convex mirror is a spherical mirror with its reflective surface bulging outward, away from the incident light. It is also called a diverging mirror since it diverges the incoming light rays.

The image formed by a convex mirror is always virtual, meaning that it cannot be projected on a screen. It is formed by the apparent intersection of the reflected light rays, and it appears to be behind the mirror. Since the light rays are diverged by the convex mirror, the image produced is always smaller than the actual object. Hence, option e) is false.

The correct answer is -50 and 0 m/s. After the collision, the velocity of block a is -50 m/s and after the collision, the velocity of block b is 0 kg·m/s.

In an elastic collision, both momentum and kinetic energy are conserved. To find the velocities of blocks a and b after the collision, we can use the following equations:

Momentum before collision = Momentum after collision
m1v1 + m2v2 = m1v1' + m2v2'
where m1 and m2 are the masses of blocks a and b, v1 and v2 are their initial velocities, and v1' and v2' are their final velocities.
Let's plug in the values given in the question:
m1 = 2 kg, v1 = 50 m/s
m2 = 4 kg, v2 = -25 m/s
Using the equation, we can solve for v1' and v2':
(2 kg * 50 m/s) + (4 kg * -25 m/s) = (2 kg * v1') + (4 kg * v2')
100 kg·m/s - 100 kg·m/s = 2 kg·v1' - 4 kg·v2'
0 kg·m/s = 2 kg·v1' - 4 kg·v2'
Divide both sides by 2 kg:
0 kg·m/s = v1' - 2 kg·v2'
Now, let's solve for v1':
v1' = 2 kg·v2'
Substituting the values given:
v1' = 2 kg * (-25 m/s)
v1' = -50 m/s
Similarly, we can solve for v2':
0 kg·m/s = -4 kg·v2'
Divide both sides by -4 kg:
0 kg·m/s = v2'
Therefore, -50 and 0 m/s are the right answers.

The cross-sectional area of the second wire is 1/16th that of the first wire. The resistance of the second wire is four times that of the first wire.

The resistance of a wire is given by the formula:

R = ρ × L / A

where R is the resistance, ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire.

Since both wires are made of the same material, their resistivities are the same. Let's denote the length and diameter of the first wire by L1 and D1, respectively, and the length and diameter of the second wire by L2 and D2, respectively. We are given that:

L2 = L1 / 2

D2 = D1 / 2

The cross-sectional area of a wire is given by the formula:

A = π × (D/2)^2

Substituting the given values, we have:

A1 = π × (D1/2)^2

A2 = π × (D2/2)^2

= π × (D1/4)^2

= (1/16) × A1

Therefore, the cross-sectional area of the second wire is 1/16th that of the first wire.

Now we can use the formula for resistance to find the resistance of the second wire:

R2 = ρ × L2 / A2

= ρ × (L1/2) / (1/16 × A1)

= (ρ × L1 × 16) / (2 × A1)

Since the first wire has a resistance of R1, we can substitute its value:

R2 = (ρ × L1 × 16) / (2 × A1)

= (ρ × L1 × 16) / (2 × π × (D1/2)^2)

= 4 × R1

If you measured the apparent brightness of two stars just like the sun and found that star A appears four times brighter than star B, it means that star A has a higher luminosity than star B. This is because the apparent brightness of a star depends on both its luminosity (intrinsic brightness) and its distance from Earth.

The apparent brightness of star A is four times that of star B, indicating that star A is either closer to Earth or has a higher luminosity. However, if we assume that both stars are at the same distance from Earth, then the difference in their apparent brightness is solely due to their intrinsic brightness. Therefore, star A has a luminosity four times that of star B.

Explanation: The apparent brightness of a star is the amount of light that reaches Earth from the star per unit area per unit time. It is measured in units of flux (energy per unit time per unit area) and depends on the star's luminosity and its distance from Earth. The luminosity of a star is its intrinsic brightness, or the amount of energy it emits per unit time, and is measured in units of power (energy per unit time).

In this scenario, we are comparing the apparent brightness of two stars that are just like the sun, meaning they have the same intrinsic brightness. If we measure their apparent brightness and find that star A appears four times brighter than star B, then we can conclude that star A has a higher luminosity than star B. This is because the apparent brightness of a star is inversely proportional to the square of its distance from Earth, and if we assume that both stars are at the same distance, then the difference in their apparent brightness is solely due to their intrinsic brightness.

The form of energy stored in a stretched spring is elastic potential energy. When a spring is stretched or compressed, it possesses potential energy due to the deformation of its structure.

This potential energy is called elastic potential energy because it is associated with the elasticity of the spring.

As the spring is stretched, work is done to overcome the forces within the spring that resist the change in its length. This work is converted into potential energy, which is stored in the spring. The amount of potential energy stored in the spring is directly proportional to the amount by which it is stretched or compressed.

When two forces are simultaneously applied to a spring in opposite directions, it may result in elongation or contraction of the spring, depending on the magnitude and direction of the forces. If the applied forces are strong enough to overcome the spring's elasticity, the spring will undergo deformation and exhibit elongation or contraction. This deformation is a manifestation of the stored elastic potential energy being converted into mechanical energy.

Shear, bending, and intermolecular binding energy are not directly related to the stretching of a spring.

The slope angle of the road is approximately 7.64°.

we can calculate the slope angle of the road by following these steps:

Step 1: Convert the car's speed to meters per second.

60 km/h * (1000 m/km) / (3600 s/h) = 16.67 m/s

Step 2: Calculate the work done by the engine per second (power) to overcome air resistance.

Power = Force * velocity

Power_air_resistance = 450 N * 16.67 m/s = 7500.5 W

Step 3: Calculate the total power supplied by the engine in watts.

38 kW = 38000 W

Step 4: Determine the power used to overcome the slope.

Power_slope = Total power - Power_air_resistance

Power_slope = 38000 W - 7500.5 W = 30499.5 W

Step 5: Calculate the force exerted by the car to ascend the slope.

Force_slope = Power_slope / velocity

Force_slope = 30499.5 W / 16.67 m/s = 1830 N

Step 6: Calculate the gravitational force acting on the car.

Force_gravity = mass * gravity

Force_gravity = 1400 kg * 9.81 m/s² = 13734 N

Step 7: Calculate the sine of the slope angle.

sin(slope_angle) = Force_slope / Force_gravity

sin(slope_angle) = 1830 N / 13734 N = 0.133

the expression for the conductive heat current q becomes:

Explanation:The conductive heat current, q, through a frustum (a truncated cone) can be expressed using the following formula:

q = -k * A * dT / dx

where k is the thermal conductivity of the material, A is the cross-sectional area through which heat is flowing,

dT is the temperature difference between the hot and cold sides (i.e. th - tc), and dx is the distance over which heat is flowing.

For a frustum, the cross-sectional area A varies with the distance from the base of the cone.

We can use the formula for the area of a circle to find that A = πr^2, where r is the radius of the circle.

For a frustum, the radius changes from r1 at the base to r2 at the top, so we need to use the average radius, (r1+r2)/2.

Therefore, the expression for the conductive heat current q becomes:

q = -k * π * ((r1+r2)/2)^2 * (th - tc) / L

where L is the height of the frustum.

This equation gives us the amount of heat flowing through the frustum per unit time (i.e. the heat current)
