<span>3730 N/C
The intensity of the electric field follows the inverse square law. Since everything except the distance is remaining constant, then the force will vary with the inverse square of the ratio of the change. So first, lets calculate the ratio of the change in distance.
22.3 / 7.8 = 2.858974359
And since we actually want the square of the distance...
2.858974359^2 = 8.173734385
And since the distance increased, that means the force will decrease. So we get
30500 / 8.173734385 = 3731.464538
Rounding to 3 significant figures gives 3730 N/C.</span>
In a completed free body diagram, the diagram should show the magnitude and direction of the body's motion.
Yes it is because it has all the characteristics of one
The sun is unremarkable
There are countless stars with the same attributes as the sun throughout the universe
Answer:
Total momentum before and after the collision = 76800 kgm/s along north.
Explanation:
Let positive x axis represent east and positive y axis represent north.
Momentum is conserved, that is total momentum before and after the collision are same.
A 1200 kg car traveling north at 14 m/s is rear-ended by a 2000 kg truck traveling at 30 m/s.
That is 1200 kg is moving north at 14 m/s and 2000 kg truck is also moving north at 30 m/s.
Momentum of car = 1200 x 14 j = 16800 j kgm/s
Momentum of truck = 2000 x 30 j = 60000 j kgm/s
Total initial momentum = 16800j + 60000j = 76800 j kgm/s
Total momentum before and after the collision = 76800 kgm/s along north.
Answer:
Explanation:
Well, which is it, level ground or sloping upward at a ratio of 1 m rise for every 5 m of run?
I will ASSUME you mean the shadow is 32 m long as measured along the 1:5 slope and the sun is 55° above the horizon.
The ground slope to horizon is
arctan (1/5) = 11.31°
The "top" end of the shadow is above the tower base by
32sin11.31 = 6.2757 m
The "top" end of the shadow is a horizontal distance from the tower base of
32cos11.31 = 31.3786 m
The tower height above the "top" of the shadow is
h = 31.3786tan55 = 44.8132 m
so the tower height is
44.8132 + 6.2757 = 51.0889 = 51 m
