In the oscillating spring ball system, what is true about the energy of the ball when it is located at its amplitude? Select the
1 answer:
When the maximum amplitude is reached, the body is also positioned in the maximum position which it can reach. At that point, the maximum potential energy stored in the system will therefore be taken.
However, when it reaches the maximum amplitude it is also in a change of direction of the velocity vector, reaching its minimum point in magnitude, thereby generating the kinetic energy to become zero.
Therefore of the options shown, the correct answer would be B.

Answer:
distance difference would a) increase
speed difference would f) stay the same
Explanation:
Let t be the time the 2nd skydiver takes to travel, since the first skydiver jumped first, his time would be t + Δt where Δt represent the duration between the the first skydiver and the 2nd one. Remember that as t progress (increases), Δt remain constant.
Their equations of motion for distance and velocities are
Their difference in distance are therefore:
(As
So as time progress t increases, Δs would also increases, their distance becomes wider with time.
Similarly for their velocity difference
Since g and Δt both are constant, Δv would also remain constant, their difference in velocity remain the same.
This of this in this way: only the DIFFERENCE in speed stay the same, their own individual speed increases at same rate (due to same acceleration g). But the first skydiver is already at a faster speed (because he jumped first) when the 2nd one jumps. The 1st one would travel more distance compare to the 2nd one in a unit of time.
Answer:
d.100 meters
Explanation:
The diameter of the Milky Way Galaxy is approximately 100,000 light years.
Here we are using 1 millimiter (1 mm) to represent 1 light-year (1 ly). So, we can set the following proportion:
and by finding x, we find the diameter of the Milky Way Galaxy in the scale used:
so the correct answer is
d. 100 meters
