Answer:
acceleration of the car is 3 m\s^2
Explanation:
from rest means the initial velocity (vi) is zero
time = 5s
final velocity (vf) = 15m\s
a = vf - vi \ t
a = (15-0) \ 5
a= 3 m\s^2
which means that the car is speeding up 3 meters every second
micrometer is used to measure the diameter of a thin wire
Answer:
.
Explanation:
Since no external force is acting on the system.
Therefore, Total energy remains constant before and after.
So, Total energy of system= energy due to potential applied+kinetic energy

(Here v=velocity ,V=potential ,q=charge and m=mass).
Putting values .
We get,
.
At point B charged particle is moving faster as compared to point A.
Hence, it is the required solution.
Answer:
kinetic energy
Explanation:
because it is at the top going down
Because ice is less dense than liquid water,
its melting point is lowered under high pressures.
A long standing theory says that this is what causes ice to be slippery:
As you step on it, the pressure of your weight causes the top layer to my into water.
