V = [4/3]π r^3 => [dV / dr ] = 4π r^2
[dV/dt] = [dV/dr] * [dr/dt]
[dV/dt] = [4π r^2] * [ dr/ dt]
r = 60 mm, [dr / dt] = 4 mm/s
[dV / dt ] = [4π(60mm)^2] * 4mm/s = 180,955.7 mm/s
You could say almost anything.
For example:
phones,
cars,
computers,
clocks,
hydraulics,
bicycles,
the hadron collider,
Planes,
and so on.
Answer: 2 seconds is the unit rate.
Explanation:
We know that Jason does 30 pushups in 60 seconds at a constant rate, and we know that each push up takes 2 seconds.
then, we can write this as 30 pushups/60 seconds = (1/2) pushups per second.
Here, two seconds represents the time needed to do one pushup, is the unit rate (this means that we need 2 seconds to have a unit "one pushup")
Answer:
A and B is positive charge
C_negative
Explanation:
because when an ebonite is rubbed with fur produce negative charge due to law of electrostatic like charge repel and unlike attract
1# The ball flying through the air has two types of energy, kinetic from its velocity and potential from its height off the ground.
