Answer:
kE=0.0735 J
Explanation:
Given that
Radius ,R=10 cm = 0.1 m
Mass ,m= 3 kg
Angular speed ,ω = 3.5 rad/s
We know that moment of inertia for solid sphere given as
Kinetic energy
Now by putting the values
kE=0.0735 J
Therefore the kinetic energy will be 0.0735 J
The surface of the rock eroded
Answer: A material called moderator is used to slow down the neutrons released during nuclear fission. The source's neutrons have a high speed and energy. The neutrons' speed is slowed by heavy water or graphite moderators.
Explanation:
Answer:
c. Slowly slide down the incline and then stop.
Explanation:
The first block slides down a rough incline since friction forces are strong enough to countereffect the effects of gravity forces and friction force is directly proportional to mass. Hence, a greater mass means higher friction forces. Net acceleration is zero.
The smaller block has a greater mass, it slides down the incline and decelerates before stopping. Net acceleration is negative.
The correct answer is c.
Because without Si there wouldn't be units of measurements.
So SI is t<span>he international system of units of measurements.</span>
