Answer: 20 meters
Explanation:
This situation is related to vertical motion, especifically an object in free fall, and the parametric equation that describes this motion is:
Where:
is the stone's final height
is the stone's initial height
is the initial speed of the stone
is the time the stone is falling
is the acceleration due gravity
Isolating according to the given information:
Finally:
This is the distance the stone fell
1,000 milligrams = 1 gram
2,000 milligrams = 2 grams
3,000 milligrams = 3 grams
4,000 milligrams = 4 grams
Answer:
light potential energy is converted into electrical potential energy.
Explanation:
A solar heat absorbs the light that creates pairs of electron - holes, these free charges when moving create a current, the light energy stored in the radiation is converted into electrical energy within the n-p junctions.
In summary, light potential energy is converted into electrical potential energy.
Answer:
(a) The angular displacement of the toy is 18.85 rad.
----
(b) The toy's angular velocity is 6.284 rad/min.
----
(c) if the counterclockwise rotation is in negative direction, the angular acceleration will be positive when the toy is turned off and vice versa.

Answer:
At the Launch point
Explanation:
We are told that after the explosion, one of the halves landed at the point Y, which is a distance of 2R to the right side of the launch point.
This means that the only way one half of the object would have gone double the original distance of R is if it's velocity was two times that of the initial velocity. Furthermore, the only way that will make sense is if the other half fell straight down. So In conclusion, if air resistance is neglected, the other half will land at the initial velocity point which is at launch point.
