Answer:</h2>
(d) it is freely falling but it has a high tangential velocity.
<h2>
Explanation:</h2>
The Moon does not crash into the Earth because it is freely falling but it has a high tangential velocity, that is, actually the moon is falling toward the earth, but since it's moving so fast, then it will never hit the earth. The moon is so far away from the earth and move so fast that it falls around the earth in a continuous circular path. In other words, the high tangential velocity makes the moon to move around the earth. If the moon was moving slowly, gravity would make the moon to fall into the earth.
Answer:
wrong answer because m=100
A is the correct answer.
The less the mass of something, the faster the kinetic energy.
Hope this helps :)
NOTE: The strength of an electromagnet is directly proportional to not only the current but the number of windings. Doubling the number of windings doubles the strength of the magnet.
Answer:
a) 20 m/s
b) 37.5 m)s
Explanation:
Average speed = total distance ÷ total time
=> (a) average speed of a car that travels 400m in 20s
= 400/20 = 20 m/s
& (b) average speed of an athlete who runs 1500m in 4 minutes (or 4×60=240 seconds)
= 1500/240 = 37.5 m/s
