A. Radioactive decay does not result in heat. Gravity also does not result in heat. In the Earth's mantle, it is highly unlikely that the radiation from the sun would reach that deep into the earth.
Answer:
Pressure
Explanation:
The measure of how much force is applied to an object from gas particle bouncing into it is called pressure.
Pressure is defined as the force per unit area on a body.
Mathematically;
Pressure =
The pressure of a gas is the combined force with which gas molecules bombard a unit area of the wall of the container. It is the sum of all tiny pushes on the wall of the container.
Various units of pressure are atm, mmHg, torr, pascal e.t.c
Answer:
<h2>320</h2>
Just use F =ma where m is mass and a is acc.
Answer:
Using
Period ( P) is given as
P~√(L/g).
a) since mass has no effect on the period of a pendulum. So, the period will remain 1.8seconds
b) using the formula above ,period varies with the square root of the length. Thus , when the length doubles, the period is multiplied by √2. So, the period is 1.8s*√2 = 2.54s
c) in this case, the period is multiplied by √(1/2).
1.8√(1/2)=1.27s.
d) amplitude of the pendulum doesn't affect the period (unless itsvery high, so, the period is still 1.8s
