Answer:

The Correct Answer is A

Explanation:

Soil is the resource that must be protected and conserved.
Soil conservation is the set of management strategies for preventing the top layer of the soil from being eroded by the earth's surface.
Soil conservation is a process to keep the quality of the soil by protecting the soil from erosion and saving its losing nutrients.

VLD [36.1K]

Answer:

6.48*10⁻⁷ C

Explanation:

By definition, the capacitance of a capacitor is expressed as follows:

$C =\frac{Q}{V}$

where Q is the charge on one of the plates of the capacitor, and V the potential difference between the plates.
The maximum electric field, the potential difference, and the distance between plates are related by the following expression:

$V = E_{max} * d$

Replacing by the givens, we can find V as follows:

$V = 6.0e6 V/m * 0.00108 m= 6480 V$

Now, we can find the maximum charge Qmax, as follows:

$Q_{max} = C*V = 1e-10F* 6480 V = 6.48e-7 C$

The maximum charge that the capacitor can hold is 6.48*10⁻⁷ C.

The compressor of an air conditioner draws an electric current of 23.7 A when it starts up. If the start-up time is 2.35 s long,

defon

Answer:

Electric charge, Q = 55.69 C

Explanation:

It is given that,

Electric current drawn by the compressor, I = 23.7 A

Time taken, t = 2.35 s

We need to find the electric charge passes through the circuit during this period. The definition of electric current is given by total charge divided by total time taken.

$I=\dfrac{q}{t}$

Where,

q is the electric charge

$q=I\times t$

$q=23.7\ A\times 2.35\ s$

q = 55.69 C

So, the electric charge passes through the circuit during this period is 55.69 C. Hence, this is the required solution.
