A mass of 0.400 is raised by a vertical distance of 0.450m in the earths growth gravitational field. what is the change in its gravitatioanal potential energy? show your work

w = 1.766 Joule

Explanation:

Work = Force × Distance

In this case the Work done is stored in body as Gravitational potential energy, so , W = P. E. = mgh

Here m = 0.400 kg ( unit not given in the question if in other unit may be converted to Kg), g = 9.81 m/s² and h= 0.450 m

w =  0.400 kg × 9.81 m/s² × 0.450 m

w = 1.7658 kg m²/s²  =  1.766 Joule  or (Nm)

Complete question: A mass of 0.400 kg is raised by a vertical distance of 0.450 m in the earth's gravitational field. What is the change in its gravitational potential energy?

1.764 J

Explanation:

Gravitational Potential Energy: This ca be defined as the energy possessed by a body due to its position in the gravitational field. The S.I unit is J.

The expression for change in Gravitational potential energy is

ΔEp = mgΔh Equation 1

Assuming the ground level = 0 m

Where ΔEp = change in Gravitational potential energy, m = mass , g = acceleration due to gravity, h = change in height.

Given: m = 0.40 kg, Δh = 0.450 m, g = 9.8 m/s²

Substitute into equation 1

ΔEp = 0.4(0.45)(9.8)

ΔEp = 1.764 J

Hence the change in gravitational potential energy = 1.764 J

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
