The work done is 1764 J

Explanation:

The work done in lifting an object is equal to the gain in gravitational potential energy of the object:

W=mg \Delta h

where

m is the mass of the object

g is the acceleration of gravity

\Delta h is the change in height of the object

For the object in this problem, we have

m = 100 kg

g=9.8 m/s^2

\Delta h = 3 m -120 cm = 3 m- 1.20 m = 1.80 m

Therefore, the work done is

W=(100)(9.8)(1.80)=1764 J

What is the mathematical relationship between wavelength and energy transmission?.
Tomtit [17]

Answer: Wavelength is related to light and also related to energy. The shorter the wavelengths and the higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
