Answer:
the gravitational pull is stronger the closer the object is to the magnet but gets weaker as you move the object away from the magnet
Explanation:
if you hold a magnet right over a nail it immediately shoot up onto the magnet
were as if you hold it at a distance it will move but not as fast
Answer:
<em>The change in momentum of the car is 3575 Kg.m/s</em>
Explanation:
<u>Impulse and Momentum</u>
The impulse (J) experienced by the object equals the change in momentum of the object (Δp).
The formula that represents the above statement is:
J = Δp
The impulse is calculated as
J = F.t
Where F is the applied force and t is the time.
The car hits a wall with a force of F=6500 N and stops in 0.55 s. Thus, the impulse is:
J = 6500 * 0.55
J = 3575 Kg.m/s
The change in momentum of the car is:
The change in momentum of the car is 3575 Kg.m/s
Answer:
Haven't done this but I think it will increase by 73.29% not too anyone correct me if I'm worng
Answer:
The potential energy in the water will be 0.0769 mJ
Explanation:
We know that energy stored in the capacitor due to charge is given by
From the relation we can see that potential energy is inversely proportional to the capacitance
And we also know that capacitance is directly proportional to the dielectric constant
So the new potential energy will be
So the potential energy in the water will be 0.0769 mJ

is that a question or a statement lol
