Answer: work
Explanation:
Often in physics, work is defined as the use of force to move an object. Technically, work is actually a change in energy caused by a force external to the system. The formula for work is W = F⊥d or W = FdcosΘ. Using this formula, we can see that work is just when a force is applied for a certain displacement. In simpler terms, that's just a force used to move an object a certain distance.
As a wave enters a different medium the characteristic that does NOT change is the frequency.
Answer:
Chidera is the stronger individual pushing the box with a net force of 5N to the left.
Explanation:
Chidera is using more force meaning they are stronger and the net force is 5N because when you plug in the equation
F1 = 30 + F2 = -25 = 5N
you get 5N
Answer:
<h2>An unbalanced force acting on an object causes it to accelerate. There are two points to note about the acceleration of an object when an unbalanced force acts on it. The bigger the unbalanced force acting on the object the bigger the acceleration of the object.</h2>
Explanation:
Answer:
3000gm/s
Explanation:
Mass = 200
v = 5
u = 10
Momentum = mass(v - u)
But because the ball is returning through the same path
Momentum = m(v + u)
Ft = 200 ( 5 + 10)
= 200 x 15
= 3000gm/s
