Answer:
Explanation:
The man is moving on a circular path . The reaction of wall is providing centripetal force .so
R = mv² / r
Frictional force = μR where μ is coefficient of friction
= μ x mv² / r
Frictional force = μ x mv² / r
Solar energy, because of solar panels, hydroelectricity from a dam, or fossil fuels. fossil fuels would be the most ideal because it is more commonly used
Answer:
Explanation: Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force.
Newton's Third Law states that for every action there is an opposite and equal reaction:
If the gravitational force of the Earth on the Moon is F then the gravitational force of the Moon on the Earth is also F
The answer would be 5.6x10^5
