Answer: c) the sun is the most massive object; gravitational attraction is related to mass.
Explanation:
Gravitational pull exists between any two objects having mass.
where symbols have their usual meaning.
All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.
Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
Answer: Galileo's laws of Motion determined that the natural state of an object is rest or uniform motion, objects always have a velocity, sometimes that velocity has a magnitude of zero rest. objects resist change in motion, which is called inertia.
Explanation:
Answer:
a) Δp = -2.0 kgm / s, b) Δp = -4 kg m / s
Explanation:
In this exercise the change in moment of a ball is asked in two different cases
a) clay ball, in this case the ball sticks to the door and we have an inelastic collision where the final velocity of the ball is zero
Δp = p_f - p₀
Δp = 0 - m v₀
Δp = - 0.100 20
Δp = -2.0 kgm / s
b) in this case we have a bouncing ball, this is an elastic collision, as the gate is fixed it can be considered an object of infinite mass, therefore the final speed of the ball has the same modulus of the initial velocity, but address would count
v_f = - v₀
Δp = p_f -p₀
Δp = m v_f - m v₀
Δp = m (v_f -v₀)
Δp = 0.100 (-20 - 20)
Δp = -4 kg m / s
