Answer:
The speed, magnitude of the velocity, magnitude of the angular velocity, magnitude of the centripetal acceleration, magnitude of the net force and direction of the angular velocity are constant.
Explanation:
In uniform circular motion we have a centripetal acceleration of constant magnitude but changing direction (since it points to the center of the circle from the object). The same goes for the net (centripetal) force since F=ma. This makes the magnitude of the velocity (speed) constant but its direction changes, although keeping spinning in the same direction, which makes its angular velocity constant in both magnitude and direction.
Answer:
0.91 J
Explanation:
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
For the lemming in this problem, when he jumps, we have:
m = 0.0780 kg is the mass
v = 4.84 m/s is the speed
Substituting into the equation, we find:

<span>The advantage of using an electromagnet rather than a regular magnet is that an electromagnet is stronger and you can control the power of the magnet. </span>

This is a number of days two users have been sending a picture or video to each other.
In the general term of a streak...
An irregular line left from smearing or a continuous series of like events.
It all depends on the context.
