How much work is done by the force if the object moves from x = 0.15 m to x = 0.60 m ?

Mass does not change thus the object would have the same mass in ay planet or the moon.

What is the mass?

We need to look at the mass of the body as the quantity of matter that we can find in the body. This implies that the more of matter that we can find in a particular object, the more the mass of the object. It is also possible to define the mass as the quantity of the inertia in an object. These are the basic ways that the mass of the object could be considered or understood in this case.

We know that the mass of the object does not change. This is because the quantity of the matter that an object has is not going to change no matter where the object is found whether on the earth or in the moon.

Having said this, we can now agree that the mass of the object would stay the same both on earth and in the moon.

The acceleration of the cheetah is 4.07 m/s^2.

Acceleration is the rate of change of the velocity of an object with respect to time. The unit of acceleration is meter per seconds squared (m/s^2). The equation of acceleration is given below.

a = (v_f - v_i)/t

Where a = acceleration, v_f = final velocity, v_i = initial velocity and t = time.

Here, the final velocity = 26.5 m/s, initial velocity = 0 m/s (cheetah is at rest) and time = 6.5 s. The acceleration of the cheetah will be,

a = (26.5 - 0)/6.5

a = 4.07 m/s^2

The speed of the bat swing decrease as the mass of the bat increases because mass is inversely proportional to velocity squared if the centripetal force is constant.

[tex]F_{c}[/tex] = m v² / r

[tex]F_{c}[/tex] = Centripetal force

m = Mass

v = Velocity

r = Radius

Rearranging for v,

v² = [tex]F_{c}[/tex] * r / m

Since [tex]F_{c}[/tex] and r is constant,

v² ∝ 1 / m

Since v² is inversely proportional to m and vice-versa, as the mass of the bat increases, speed of the bat swing decreases.

A centripetal force is responsible for making a body follow a curved path. The direction of centripetal force is perpendicular to the motion and towards the center of curvature.

Therefore, the speed of the bat swing decrease as the mass of the bat increases because mass is inversely proportional to velocity squared if the centripetal force is constant.

The small rocket will be take time 1296 sec.

We are given that,

The thrust of the rocket  = F = 35N

The velocity of the rocket = v = 0.63m/s

The mass of the satellite = m = 72000kg

Therefore , to get time t of the rocket when it would be fired and we use the equation such as , the product of the mass and velocity of an object i.e. known as momentum (p).

p = mv

Where p is the momentum of the rocket, m is the mass and v is the velocity of the rocket.

Since , here we can write Newtonian relations such as, Momentum is equivalence as a function of Force (F) and time (t) which is given as,

p = F t

So that from above two equation we can write as,

mv = Ft

t = mv/F

t = {(72000kg) ×(0.63m/s)}/35N

t = 1296 sec

The flow of charge across the cell membrane creates an electric current. Cells control the flow of specific charged elements across membranes using proteins that reside on the cell surface and create openings for specific ions to pass through. These proteins are called ion channels.

For example, if there is a voltage difference between one arm and the other a current will flow through the body. The human body has a higher impedance to DC current than to its AC current.

If an object is changing its direction or the speed of the object is changing then the object is said to be accelerating.

Acceleration is the rate at which speed and direction of velocity change over time. A point or object moving straight ahead is accelerated when it accelerates or decelerates. Even though the speed is constant, motion on a circle accelerates because the direction is constantly shifting.

An object is said to be accelerating if its velocity is changing, whether the change in velocity is constant or varies by a fixed amount.

Since acceleration is a vector quantity—which means it has both a magnitude and a direction—it follows that an object is said to be accelerating if its direction is changing.

Here, W is the force due to gravity which is its weight.

There is a frictional force, f acting towards the slope.

N is the normal force.

The car will remain at rest if no force is acting on the body.

The weight can be resolved into sine and cosine components.

The horizontal component of weight cancels out the normal force and the vertical component of weight cancels the frictional force.

A prism is a translucent, triangular object composed of glass or plastic (or any transparent material). Refraction is a phenomenon that causes white light to curve when it passes through a prism. Light is bent when it travels from one medium (like air) to another medium through the process of refraction (like water or glass).

The refractive index of an optical medium is a dimensionless quantity that describes how efficiently the medium bends light. The amount of light that enters a substance is refracted or bent depends on the substance's refractive index.

Apparent depth is the distance between the real depth of an item and its image when it is submerged in a transparent medium, which is lowered by a factor equal to the relative index of refraction of the medium with regard to air.

apparent depth is equal to actual depth / refractive index.
