Answer:
Momentum change of the rock = 3835 kgm/s
Chane in earth's velocity = 6.4 x 10⁻²² m/s
Explanation:
m = 50.0 kg, M = 6.0 x 10²⁴ kg
d = 300.0 m
final velocity of rock = v, v² = 2gd = 2 * 9.81 * 300, so v = 76.7 m/s
Momentum change of the rock = mv = 50.0 * 76.7 = 3835 kgm/s
Inital momentum of the rock+earth system = 0
final momentum = 0 (momentum conservation)
momentum of rock and momentum of earth are same magnitude and opposite directions.
mv - MV = 0
Chane in earth's velocity = mv/M = 3835/(6.0 x 10²⁴) = 6.4 x 10⁻²² m/s
One method of creating a magnet is coiling wire around a nail and running electricity through it, to make the magnet stronger coil more wire and increase the Voltage.
The characteristic of life would be homeostasis. Homeostasis regulates the variables in which internal conditions remain stable and consistent. This type of regulation is the regulation of temperature and the balance between acidity and alkalinity, also known as pH. Hope this helps! :)
