I’m not sure I’m just gonna assume that the flashlight closed too the wall is gonna be brighter because most of it’s light is directed on the wall rather then the one further back is kinda pointed everyone else & I think it relates to stars as if the brighter the star the closed it is to earth ?
Answer:
v = 12.79 m/s
Explanation:
Given that,
The mass of a car, m = 1200 kg
Momentum of the car, p = 15 350 kg-m/s
We need to find the velocity of the car. We know that, the formula for the momentum of an object is given by :
p = mv
Where
v is the velocity of the bject
So,
So, the velocity of the car is 12.79 m/s.
Mechanical advantage is defined as
MA = 4
now we will have
as we need to pull up a box of weight 200 N
now by above formula we can find how much force it requires to pull up the box
so it requires 50 N force to pull the weight of 200 N
