Answer:

Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)



The ratio is obtained by multiplying each side by
:


The value of this ratio is:

Answer:
A tornado can, surprisingly, cause a supercell, so the answer would be C.) tornado
Explanation:
When cold, dry, and polar air meet warm, moist tropical air, the atmosphere becomes unstable causing a supercell.
Final Answer:
C.) tornado

Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.
<em>Quantities that determine the kinetic energy of a body are its </em><em>mass and velocity </em>
Answer: <em>mass and velocity </em>
Explanation:
The kinetic energy of a body is the energy possessed by an object by virtue of its motion. It is given by the equation

Where m represents mass of the body and v represents its velocity.
Two bodies of equal velocity but different mass the heavier body will have greater kinetic energy. When an object is at rest its velocity is equal to zero. Thus its kinetic energy will be zero. Hence it can be concluded that only moving bodies have kinetic energy.
Stationary objects placed at a height possess potential energy which is the energy by virtue of their position or configuration. The total mechanical energy of a system is the sum of potential and kinetic energy.
Direction of resultant force in circular motion is directed towards the center of the circle. Hence vector B is the direction of the resultant force.
