Answer:
V= 150
Explanation:
9000/60 or 9000 ÷ 60 is 150
The formula is displacement divided by change of time.
Yes. Partly. Also on the size and shape of the object, and also on what material it's IN at the time ... like air, water, Helium, Jello, etc.
Answer:
Transfer
Explanation:
bc energy cannot be created not destroyed so instead it transforms or gets transferred.
Answer:
The question is incomplete.
It asks you to use the formula W = F * D (force times distance)
But the question only gives the work W in joules.
You would need to know the weight of the object to get the distance moved or the distance moved to get weight if you are only given the work done.
Incidentally, the mechanical advantage in diagram is A is 1 whereas the mechanical advantage in B is 2.
So in B you would apply 1/2 the force as in A and would have to move the rope twice as far as in A to do the same amount of work.
The answer is b . Because they <span>are gaps in the geologic record that may indicate episodes of crustal deformation, erosion, and sea level variations. They are a feature of stratified rocks, and are therefore usually found in sediments (but may also occur in stratified volcanics)</span>
