Rainbows on an oily street after it's been raining. The colors in floating bubbles. Rainbows in the sink when using dish-soap.
Answer:
65 N
Explanation:
Assuming that the ball was at rest hence initial momentum = 0
Final momentum = mv = 1Kg × 13 ms-1 = 13 kgms-1
But
Ft= mv according to Newton's law
F= mv/t
F= 13kgms-1/0.2s
F= 65 N

Of course. Wind is air in motion, and the gases in air are composed of
all the usual familiar stuff ... atoms, molecules, mass, etc. That's how
the wind moves things ... it has momentum and kinetic energy, which
get transferred to the things that move in the wind.</span>
Answer:
Taking water and oxygen from Earth is rather expensive and hard to do.
Explanation:
Without water and oxygen, travel to other planets is basically impossible
All processes that exist obey the Law of Conservation of Mass and Energy. These laws state that mass and energy can neither be made nor destroyed. Thus, they are only transferred from one system to another. The more technical term is that, mass and energy can be transformed. Energy can be in different forms: kinetic and potential energy.
Mass transfer happens when, for example, a deer eats grass. The grass contains mass and energy from the soil that gives it nutrients. When the deer gets eaten by a lion, the mass and energy transfers to them, as well. The cycle continues in the ecosystem.
