What models are you talking about
The weight is the force experienced, whereas the mass represents the actual quantity of matter inside a body..
weigh on the surface of the earth is equal to mg
mass is m
and at the centre weight is 0 due to 0 acceleration that's 0 g
but mass is always constant and remains m, no matter where you are
Answer:
2.11eV
Explanation:
We know that speed of light is it's wavelength times frequency.
Planck's constant is 
The energy gap is calculated by multyplying the light's frequency by planck's constant:
Hence, the energy gap is 2.11eV
Answer:
The heavier something is, the harder it is to slow down. As such, higher amounts of mass result in a lower rate of slowing.
Answer:
Both are examples of negative feedback regulation.
Explanation:
The maintenance of the homeostasis in the body is controlled by the the feedback regulation of the body. Two main types of feedback regulation are positive regulation and negative regulation.
The negative regulation occurs when the final product of the reactions inhibits the further secretion of that product. In the given examples of aldosterone and calcium mechanism, the secretion of aldosterone and calcium decreases as the normal levels are acheived in the body.
Thus, the answer is both are examples of negative feedback regulation.
