Answer: friction can help you in many ways such as when you hit the brakes on your car or when you are washing your face
Explanation:
friction happens in just about everything you do
Answer:
- <u>C = Q/∆V . So the overall strategy here is to find the potential difference ∆V corresponding to a particular Q on an object, then take the ratio.</u>
Explanation:
Capacitance is the amount of charge something can hold for a given ap- plied potential difference between separated parts of the conductor:
Answer:
25 m/s
Explanation:
First of all, we can find the acceleration the object by using Newton's second law of motion:

where
F = 20.0 N is the net force applied on the object
m = 4.0 kg is the mass of the object
a is its acceleration
Solving for a, we find

Now we know that the motion of the object is a uniformly accelerated motion, so we can find its final velocity by using the following suvat equation:

where
v is the final velocity
u = 0 is the initial velocity
is the acceleration
t = 5 s is the time
By substituting,

Answer:
D
A machine can help decrease the input force and increase the output force.
