A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speed will the sled have twice as much kinetic energy?
<span>4.2 m/s</span>
Answer:
Distance of the second child from the pivot point will be 2.66 m
Explanation:
We have given mass of the first child
Distance from the pivot point
Mass of the second child
We have to find the distance of the second child from the pivot point
For this we have to balance the moment
So
So the distance of the second child from the pivot point point will be 2.66 m

Answer:
113.7
Explanation:
maximum distance (s) = 8.9 km
reference intensity (I0) = 1 x 10^{-12} W/m^{2}
power of a juvenile howler monkey (p) = 63 x 10^{-6} W
distance (r) = 210 m
intensity (I) = power/area
where we assume the area of a sphere due to the uniformity of the output in all directions
area = 4π = 4π x = 554,176.9 m^{2}
intensity (I) =
therefore the desired ratio I/I0 = = 113.7
