Answer:
Because nothing is blocking the LIGHT!
Explanation:
Light may still be shining on the whole glass but if it wasn't there light would shine brighter than if it was there.
The answer is in chambers carved into the rock of a mountain<span>. Radioactive waste should be well disposed where they are little to no anthropogenic activity that would uncover them. </span><span>This is especially critical for high-level radioactive waste should be buried deep up to 2000 meters. While low-level radioactive waste can be buried 100 meters into the ground such as in sand, the risk is that it could contaminate the water table.</span>
5-14 m/s in 3 seconds
a=vf-vi/t
a=14-5/3
a=9/3
a=3 m/s^2
h =(3.7 - .58)m = 3.12m
Now put PE into KE and we have to use the formula:
√2gh (g = gravity and h = height) therefor:
√2 x 9.8 x 3.12
= 7.82m/s
I hope this helps!
Answer:
The engine would be warm to touch, and the exhaust gases would be at ambient temperature. The engine would not vibrate nor make any noise. None of the fuel entering the engine would go unused.
Explanation:
In this ideal engine, none of these events would happen due to the nature of the efficiency.
We can define efficiency as the ratio between the used energy and the potential generable energy in the fuel.
n=W, total/(E, available).
However, in real engines the energy generated in the combustion of the fuel transforms into heat (which heates the exhost gases, and the engine therefore transfering some of this heat to the environment). Also, there are some mechanical energy loss due to vibrations and sound, which are also energy that comes from the fuel combustion.
