Temperature is a measurement of the average kinetic energy of an object’s molecules
Answer:
F' = (3/2)F
Explanation:
the formula for the electric field strength is given as follows:
E = F/q
where,
E = Electric Field Strength
F = Force due to the electric field
q = magnitude of charge experiencing the force
Therefore,
F = E q ---------------- equation (1)
Now, if we half the electric field strength and make the magnitude of charge triple its initial value. Then the force will become:
F' = (E/2)(3 q)
F' = (3/2)(E q)
using equation (1)
<u>F' = (3/2)F</u>
Answer:
1st case; mass=40 kg
v=25m/s
K.E.=1/2[40][25]^2=12,500 J
2nd case; mass=4,000 kg
v=2 m/s
K.E.=1/2[4000][2]^2=8000J
in case 1 Kinetic energy is greater.
Explanation:
Answer:
Explanation:
To solve this problem we use the formula for accelerated motion:
We will take the initial position as our reference (
) and the downward direction as positive. Since the rock departs from rest we have:
Which means our acceleration would be:
Using our values:
