Answer:
Explanation:
We shall apply law of conservation of momentum .
m₁ v₁ = m₂ v₂
m₁ = 80 kg
v₁ = ?
m₂ = .43 kg
v₂ = 15 m /s
80 v₁ = .43 x 15
v₁ = .43 x 15 / 80
= .08 m /s
8 cm /s
option A is correct.
Law of conservation of momentum is applied only where no external force acts . Here during the period when ball was thrown , apart from internal force , external force like gravitational force was also acting but we still applied this law because the time duration of action of throw was very small
so we neglected the effect of external force . So it was just an approximation.
It will land in your lap because there's different frames of motion relative to yourself. For example, if you're running at a speed of 6 mph, it doesn't mean you'll run as fast as the Earth spins. Also, since you're on the interior of the plane, any kind of wind or weather on the outside will not affect the coin. A law to back up this claim is Einsteins Special Law of Relativity.
To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
Answer:
400Pa
Explanation:
use pressure = force/area
Answer: The origin might be from MARS
Explanation: Meteorites origin are either from Asteroid, Moon or Mars. Their origin is usually classified according to their age after using radioisotope dating. Meteorites that originate from Mars are between the age of 4.5 billion to 200 million years. Since the meteorite in question is only a billion years old, the origin would be from Mars.
