Use newton's second law: net force = m*a
in this case, m is 20kg and a is g. The net Force would be 196 Newtons
The name given to a fuel made from living organisms or their waste is a fossil fuel. Fossil fuels, in the form of oil and coal, have been utilised by mankind for approximately 100 years in order to produce energy. Today, there is a shift to more renewable energy sources such as solar, wind or wave power.
The wavelength of the radio wave is 0.303 m.
<h3>
Wavelength</h3>
The wavelength of the wave is the distance traveled by the wave.
c = fλ
where;
- c is speed of light = 3 x 10⁷ m/s
- f is frequency
- λ is wavelength
λ = c/f
λ = (3 x 10⁷ ) / (99 x 10⁶)
λ = 0.303 m
Thus, the wavelength of the radio wave is 0.303 m.

Answer: The smallest effort = 300N
Explanation:
Using one of the condition for the attainment of equilibrium:
Clockwise moment = anticlockwise moments
900 × 1 = 3 × M
Where M = the weight of the strong man
3M = 900
M = 900/3 = 300N
Therefore, 300N is the smallest effort that the strongman can use to lift the goat
