True or false conceptual physics 2 questions from chapter 25.

Physics
1 answer:
Arlecino [84]3 years ago
3 0

Answer:

Explanation:

1) TRUE; potential difference can be calculated using path integral. Since the electric field is a conservative, the potential difference can be calculated using any path.

2) TRUE; since potential due to a charge is inversely dependent on distance, at infinity the potential will be almost zero.

3) TRUE, W = q.VBA.

4) FALSE; eV is a unit for work (or) energy.

5) TRUE; since the electric force is conservative force. There will be no loss in energy, the decreased potential energy will be coverted to kinetic energy.

6) FALSE; in the direction of electric field the potential decreases.

7) FALSE; equipotential surface is perpendicular to the electric field lines.

8) FALSE; electrostatic potential is scalar quantity. It depends only on the charge and distance from it.

9) FALSE; Inside a conductor the electric field is zero but the electric potential is constant at the value that is at the surface of the conductor.

10) TRUE; as long as the field is being measured outiside the body the bodies act as point charges. So electric fields due to all types of bodies charged identically will be equal.

As altitude increases, what happens to air pressure?
Mashcka [7]

Answer:

It decreases

Explanation:

The air pressure tends to be higher on the places with the lowest altitudes, and lower at the places with higher altitudes. Basically, the air pressure is the wight of the air, and since the air is denser and heavier at the lower altitudes, the air pressure is higher, while on the higher altitudes the air is less dense, thus the air pressure is lower. So in practice we can expect that the air pressure in a low valley will be higher than the air pressure at the top of higher mountain.

(a) PE = 0.016J

(b) PE = 1470J

Explanation:

Given:

Mass, m = 4 kg

distance, x = 0.12 m

Spring constant, k = 2.3N/m

Potential energy, PE = ?

We know:

PE = \frac{1}{2} kx^2

On substituting the value we get:

PE = \frac{1}{2} X 2.3 X (0.12)^2\\\\PE = 0.016J

(b)

Mass, m = 10kg

Height, h = 15m

Potential energy, PE = ?

Acceleration due to gravity, g = 9.8 m/s²

PE = mgh\\\\PE = 10 X 15 X 9.8\\\\PE = 1470J
