. a positive charge always moves from a higher potential to a lower potential is right answer.
ira [324]3 years ago
6 0

Answer: The correct answer is "a positive charge always moves from a higher potential to a lower potential".

Explanation:

Electric potential: It is defined as the work done in moving a unit positive charge from from reference point to a particular point.

The electric potential difference is defined as the electric potential between two points. In the circuit, battery provides the potential difference so that the electron can flow in the conductor easily. The negative terminal of the battery is at lower potential and the positive terminal of the battery is at higher potential.

The electron moves from lower potential to higher potential but the direction of the current is opposite to the direction of the electron.

A positive charge is moved from a higher potential to a lower potential but the negative charge moves from a lower potential to a lower potential.

In the given problem, a positive charge is moving from rest under the influence of an electric potential. Therefore, the correct option is (a).

the amount of water returning to the earth through precipitation is blank the amount of water leaving the earth through evaporat
nalin [4]

<u>Answer:</u>

<em>The amount of water entering the earth through precipitation is equal to the amount of water leaving earth through transpiration.</em>

<u>Explanation:</u>

Rates of precipitation and evaporation vary widely according to regions and seasons. But in a global scale the rates are equal. Thus the total amount of earth’s water maintains its constancy even though there is a continuous change in forms of water.

Evaporation and transpiration are the forms in which Water leaves the earth and it returns to the earth in various forms of precipitation like rain, snow, dew, fog etc. This water then reaches ocean and land. The water that reaches the land flows as surface run off into rivers and water bodies or seep into the ground replenishing the ground water table.

Explain in your own words how the Doppler Effect is also applicable in our study of light.
arlik [135]

well in my own words, i'd saw the the doppler effect is similar to light because sound has a speed, and light does too.

so my theory is if you go fast enough everything would just become black, or maybe white? idk its hard to explain

but what my point is, is taht the doppler effect works in the same way, like if a car is moving towards you the sound is being emitted from the car and being pushed by the speed of the car making it have a much higher pitch, when the car is going away however it drops to a lower pitch due the the sound waves being DRAGGED by the car.

there hoped this helped I guess

Answer:

Explanation:

Theorem of Binomial Distribution will apply here.

n = 29 , p = .67 , q = 0.33

mean = np = 29 x .67 = 19.43

Standard Deviation = √npq

= √29 x .67 x .33

= √6.4

= 2.53
