<span><span>Imagine we have a 2 lb ball of putty moving with a speed of 5 mph striking and sticking to a 18 lb bowling ball at rest; the time it takes to collide is 0.1 s. After the collision, the two move together with a speed of v1. To find v1, use momentum conservation: 2x5=(18+2)v1, v1=0.5 mph. </span><span>Next, imagine we have a 18 lb bowling ball moving with a speed of 5 mph striking and sticking to a 2 lb ball of putty at rest; the time it takes to collide is 0.1 s.

Answer:
Living Things
Explanation:
Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Answer:
Mass, m = 665.77 kg
Explanation:
The question says that "If you try to smuggle gold bars by filling your backpack, whose dimensions are 56 cm * 28 cm * 22 cm, what would be its mass?
"
The dimension of gold bar is 56 cm×28 cm×22 cm
We know that the density of gold is 19.3 g/cm³
The mas per unit volume of a material is called its density. It can be given by :
So, the mass of the gold bar is 665.77 kg.
Answer:
Because water is water and its a liquid meanwhile plants are plants living things that you can move around.
