Answer:
(c) As 'd' becomes doubled, energy decreases by the factor of 2
Explanation:
Energy stored in a parallel plate capacitor is given by:
As capacitor remains connected to the battery so V remains constant. As can be seen from (1) that energy is inversely proportional to the separation between the plates so as 'd' becomes doubled, energy decreases by the factor of 2.
Answer:
10,600 m
Explanation:
Use range equation:
R = v₀² sin(2θ) / g
R = (433.0 m/s)² sin(2 × 64.8°) / (9.8 m/s²)
R = 14,700 m
The range is shortened by 28.1%.
0.719R = 10,600 m
Answer:
Heat conduction.
Explanation:
Heat conduction is defined as the flow of internal energy from a region of higher temperature to one of lower temperature by the interaction of the adjacent particles (e.g molecules, ions, electrons, etc.).
Thermal conduction can also be defined as the transfer of heat energy by the actual movement of microscopic particles. It is the rate at which heat is transferred.
Explanation:
The centripetal force acting on a particle is given by :

Since,


Case 1.
If 
Since, 
So, 

So, the force becomes,

F is independent of r
Case 2.
If 


So, 
So, the force is inversely proportional to the square of radius.
Case 3.
If T is independent of r, the force will be directly proportional to the radius of orbit.
Hence, this is the required solution.
Answer:
4 d
