There is no change in ocean water temperature when it is from the ocean surface to a depth of 1 km.
Given:
Velocity: 0.5 mile/minute
Time: 12 minute
Now we know that speed and velocity have the same magnitude. Hence speed=velocity=0.5 mile/min
Substituting the given values in the above formula we get
Distance = 0.5 x 12= 6 miles
Answer:
v'=0.83m/a and v=10.2m/s
Explanation:
The information that we have is:

The maximum height of the projectile is given by the equation

So, rearrange for the velocity,

Apply the conservation of momentum,

Then rearrange the recoil speed,

It seems that you have missed the given options for this question, but anyway, here is the correct answer. If humans cannot see ultraviolet waves, ultraviolet light can be used to gather evidence of a crime since u<span>ltraviolet light causes substances to fluoresce and give off visible light. Hope this is the answer that you are looking for. Thanks for posting!</span>
