Explanation:</h2>
First of all, we need to figure out what is the resistance in that line. In this problem, the total resistance is not given directly, but we can calculate it because we know it in terms of 0.51 Ω/km and since the distance from the power station to the city is 156km, then:
So we can calculate the power loss as:
Finally, the power loss due to resistance in the line is 96.09MW
With 30degree because incident angle = reflected angle
Answer: A material called moderator is used to slow down the neutrons released during nuclear fission. The source's neutrons have a high speed and energy. The neutrons' speed is slowed by heavy water or graphite moderators.
Explanation:
A). The ball was moving at zero speed at the peak.
b). The acceleration of the ball was 9.8 m/s² downward, from
the time the hand threw it until the time the hand caught it.
c). see the answer to b).
d). see the answer to b).
e). The ball was in the air for 2 (22.5/9.8) = 4.6 seconds.
f). The ball was moving down at 22.5 m/s when it was caught.
Answer:
i know it's letter A☺️
cause if you placed it on principal axis you can known the answer
