Yep. 'a', 'b', and 'c' are all accurate.
Actually, 'b' doesn't go far enough. Light is not only "faster than
anything else we know of", we now know that it's impossible for
anything with mass to ever hit that speed, so we can just quit looking.
Average velocity is the ratio of the total distance travelled to the total time spent.
Instantaneous velocity is the average velocity a body as the time tends to zero
Answer:
18*10^10 meters
Explanation:
V= d/t 10 mins = 600 seconds
3*10^8 = d/600s
(3*10^8)*(6*10^2) = d
d = 18*10^10 m
A microwave uses heat waves that keeps in side the machine to heat up the cup of water
Hope this helps :)
My suggestion would be to push the rock gently in the direction
he wants it to go. If he kicks it, then he could injure his toe, and
the large rock might take off in the direction of a vital control panel
or navigation component. By pushing it gently, he can give it a small
acceleration, assuring that it won't become a dangerous missile, and
he can control it with greater accuracy. There's no reason for the explorer
to be in a hurry. Does he have places to go ? Appointments to keep ?
Where can he go ? He's in space ! Relax ! Take care of the rock safely.
