I believe your answer would be
B. Slowing Down.
8). A rubber band is storing more elastic energy in it when it's stretched.
It's the work you had to do to stretch it.
9). Radio, TV, microwave, infrared (heat), visible light, ultraviolet light, X-rays,
and gamma rays are all part of the electromagnetic spectrum, and all of them
carry energy from one place to another.
Drinking water helps maintain nearly all processes of the human body and <em>homeostasis. </em>Further, drinking water helps,
- Digestion
- Absorption
- Circulation
- Saliva and mucus production
- Thermoregulation/homeostasis
- Lubrication of joints
- Boosts integumentary health.
- Helps in excretory systems
- Prevents dehydration of cells
- Reduces chance of hangover from alcoholic drinks.
- etc,
Succinctly, it is VERY important to drink water! Water is the source of human life and without water, we cannot survive.
The two elements are in the same period, with Element R the first element in the period and Element Q the last element.
The velocity of the red ball after the collision is 5.8 m/s
Explanation:
In absence of external forces on the system, we can apply the principle of conservation of momentum. The total momentum of the system must be conserved before and after the collision, so we can write:
where:
is the mass of the pool ball
is the initial velocity of the pool ball
is the final velocity of the pool ball
is the mass of the red ball
is the initial velocity of the red ball
is the final velocity of the red ball
Solving the equation for v2, we find the final velocity of the red ball after the collision:
