A. All natural radiation is at a level low enough to be safe
Answer:
a)
b)
Explanation:
Let the first ball throw be the point of reference, we can have following the equation of motion:
1st ball: 
2nd ball: 
a)When the 2 balls collide they are at the same spot at the same time:
b) The first ball is at its highest point when v = 0. That is
After this time, the 2 balls would have traveled through a distance of
Since
we can solve for H
Answer:
I cannot do the laws of physics cuz I hate science but I'm just dance
Explanation:
<u>it's</u><u> it's true</u>
<u>The correct answer is 580.
</u>The upward force the right tension cord exerts on the traffic light is equal to about 114.35 N. Because the stoplight is being help upright the natural force (upward force) provided by both tension cords must be equal to the gravitational (downward) force of the traffic light which is 331.
If 114 is the upward force on the right side then 216 N must be the force provided by the left side.
You then have a right triangle with the length opposite theta = about 216 and theta = 22. So sin(22)* X = 216, where X is the length of the hypotenuse, or the force found in the left cord.
with sig figs added to the mix the answer is 580 N
I believe the answer is true to the E dgenuity physics course
Work is a quantity that measures the effects of a force acting over a distance.
