a)5m/s b)5
the 5 is because you add the seconds to get 8 seconds and then do the same with the distance to get 40. 40/8 = 5. speed = 5
Velocity = displacement/change in time
V = 40/8
I just realized how unorganised my math looks but I hope this is helpfull
It is the thermal energy transferred from a hot object to a cool object.
The following statement listed above is correct.
Answer: True.
Answer:
h~=371.26m
Explanation:
when an object falls we use the equations of accelerated motion. There is only one that gives distance.

Since we have no initial velocity (started from rest) we can get rid of the (ut) term
where a we substitute g (gravitational acceleration, constant for given heights and almost 9.81m/s^2).

When visible light<span> in air enters a </span>medium<span> such as glass, the velocity of </span>light<span> decreases ... 3 by representing incident </span>light<span> as parallel </span>waves<span> with a </span>uniform<span> wavelength . ... Thus, they bunch up and stay bunched up as they run </span>through<span> the water. ... </span>wave<span> and the water </span>would<span> be the </span>medium<span> into which the </span>light wave<span> is </span>traveling<span>.</span>
