Does gravity have an effect on the potential difference of a battery?
Sonja [21]

Answer: The correct answer is "No".

Explanation:

Gravity: It is the force which causes object to fall on the earth. It is the force which attracts bodies towards each other.

Potential difference: It is defined as the potential acting between the two points. The work done in moving the unit positive charge from one location to the another location.

The potential difference in battery is caused by the electrodes. There are two terminals in battery: Negative terminal which is at lower potential and Positive terminal which is at higher potential. It forces the electrons to flow in the circuit which constitutes the current.

The gravity and the potential difference have no relation between them.

Therefore, gravity have no effect on the potential difference of a battery.

A rain cloud contains 5.32 × 107 kg of water vapor. The acceleration of gravity is 9.81 m/s 2 . How long would it take for a 2.0
Alja [10]

Answer:

20.85 years

Explanation:

2.61 km = 2610 m

2.07 kW = 2070 W

First we need to calculate the potential energy required to take m = 5.32 * 10^7 kg of rain cloud to an altitude of 2610 m is

E = mgh = 5.32 * 10^7 * 9.81 * 2610 = 1.4*10^{12}J

With a P = 2070 W power pump, this can be done within a time frame of

t = E/P = \frac{1.4*10^{12}}{2070} = 658037739 s

or 658037739/(60*60) = 182788 hours or 182788 / 24 = 7616 days or 7616 / 365.25 = 20.85 years

Veronika [31]

Answer:

D.

Explanation:

cycle.

I think it’s a cycle because a wave pattern is kind of like a type of cycle because it happens over and over again.

Which is more likely to be dangerous-a volcano that erupts frequently or a volcano that has been inactive for a hundred years? W
Korvikt [17]

Answer:

A volcano that erupts frequently.

Explanation:

Both.

But the volcano that hasn't erupted in 100 years would probably be more dangerous because you wouldn't be prepared for its explosion as you would be for the one that erupts frequently.

Glad I could help!!
