Answer:
The temperature would get warmer.
Explanation:
It indicates heat from earth’s warm interior surface. The temperature increases for about 25℃ for every single kilometer of depth.
Answer:
Part a)
Part b)
Explanation:
Magnetic field due to outer solenoid inside it is given as
Now similarly we have
magnetic field due to inner solenoid on it axis is given as
Part a)
Now if a proton is revolving around the common axis of two solenoids
then we will have
Part b)
Now proton is revolving in the field of outer cylinder only
so again we have

Explanation:</h2>
1) We will make a Free-Body Diagram representing all the upward and downward pressures exerted on the piston.
- Pressure exerted by the compressed spring (Pspring)
- Pressure due to weight of the piston (Pw)
- Atmospheric pressure (Patm)
- Initial pressure inside the cylinder. (P1)
2) We will formulate an equation balancing all upward and downward pressures.
P1= Patm + Pw + Pspring
3) We will calculate each of the pressures separately.
P = F/A
F= ks
k= 38×1000 =38000 N m
s= 2.5 /1000 = (2.5x10^-3) m
F = 38000×(2.5x10^-3) = 95 N
A = 30/10000 = (30x10^-4) m2
P = 95 / (30x10^-4)
Pspring ≅ 3167 Pa
P = F/A
F = W = mg
W = 2×9.81 = 19.62 N
A = 30/10000 = (30x10^-4) m2
P = 19.62 / (30x10^-4)
Pw = 654 Pa
P = 1atm = 101325 Pa
Patm = 101325 Pa
4) We will add all the downward pressures to reach the final answer (initial pressure inside the cylinder).
P1= Patm + Pw + Pspring
P1= 101325+654+3167
P1= 105146 Pa
FALSE.....
A molecule is made up of two identical bonded atoms.
