Answer:

Explanation:

M(a+g)

The force acting on the top box by the bottom box both having a mass of m stacked in an elevator moving upward with an acceleration of a is,

m(a +g).

Force is an external factor acting on a body to change it from the state of motion or rest. There are different types of forces such as gravitational force, nuclear force, tension force etc.

Newton's second law states that the force acting on a moving body is the product of its mass and acceleration. If the body of mass m is moving upward with an acceleration a, the force F will be equal to ma.

If the body moves downwards, then the net acceleration is the gravity g that is 9.8 m/s².

Here, both the boxes are moving upward and experience an acceleration a. The force exerted by the box at the bottom is with the acceleration g.

Thus ,the net force experienced by the box at the top by the box at the bottom is equal to F= m (a + g) .

Explanation:

When forces are balanced and mases are different, different mases experience different accelerations to maintain the constant force.

Answer:

1. directly

2. inversely

Explanation:

The relationship between the energy of a photon and its frequency is dictated by another simple equation:

E = hv = hc/λ

where E is the energy in kiloJoules per mole, h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle, λ is the wavelength of light λ in meters,  and c is the speed of light with a constant value of 300 million meters per second. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and vice versa.

Energy of a photon is directly proportional to frequency, and inversely proportional to wavelength.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form

Answer:

Gravitational potential energy

Explanation:

PE = m*g*h

m = mass

g = 9.81m/s², acceleration of gravity

h = height

So m and g stay the same but the height can change so the higher you go the higher the Gravitational potential energy.

Placing a soccer ball on the top shelf increases the Gravitational potential energy

In a gravitational field the energy possessed by an object due to a change in its position called as gravitational potential energy, it is an energy that is related to gravitational force or to gravity.

When a mass of the body  (m) is moved from infinity to a point inside the gravitational influence of a source mass (M) in absence of acceleration and the amount of work done in displacing it into the source field is stored in the form of potential energy denoted with the symbol Ug.

when external force is applied, then the  position of the body changes potential energy is equal to the amount of work done on the body by the forces.

The gravitational influence on a body at infinity is zero, then the  potential energy is zero, PE = m*g*h where m = mass, g = 9.81m/s², acceleration of gravity, h = height
