According to the Law of Inertia, our upper body was in rest and it wanted to remain in that condition.....
I am going to assume that the rider starts at rest. Using the equation for kinetic energy, the answer would be equivalent to
. The final answer would be 50 N.
<span> 1) When light is passing from a denser medium to a lighter medium ( for eg: from water to air)
2) When the angle of refraction is greater than the critical angle( angle of incidence when the angle of refraction is perpendicular to the normal) of the denser medium. </span>
<u>Answer</u>
0.1
<u>Explanation</u>
Mechanical advantage(M.A) of a machine is the ratio of work output to work input.
It can also be defined as the ratio of load to effort. It has no units since it is a ratio.
M.A = work output/work input
= load/effort
= 25/250
= 0.1
Masa is a concept that identifies that magnitude of a physical nature that allows indicating the amount of matter in a body. Within the International System , its unit is the kilogram ( kg . )
