D; solar system, because the planets are inside it.
Answer : The change in momentum of an object is equal to the impulse that acts on it.
Explanation :
Change in momentum : The change in momentum of an object is the product of the mass and the change in velocity of an object.
The formula of change in momentum is,
Impulse : An impulse of an object is the product of the force applied on an object and the change in time. Impulse is also equivalent to the change in momentum of an object.
Proof :
Hence, the change in momentum of an object is equal to the impulse that acts on it.
S=Vt
110=V(72)
110/72=V
V=1.527m/s
The measurement of sound is in decibels.
Answer:
1.03
Explanation:
0.02 has two significant decimal figures, so start by shortening 1.0090 to 2 decimal places (3 significant figures). Round up the decimal to become 1.1 and add .02 to get 1.3.
