<span>1. Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes. The following explains why many modern electronic devices use integrated circuits instead of vacuum tubes:</span>
They are much smaller and more efficient than vacuum tubes.
<span>2. The equation that is used to calculate the amount of electrical energy is the following:
E=P x tE is the energy transferred in kilowatt-hours, kWhP is the power in kilowatts, kW</span>
t is time in hours, h
3. The term voltage describes the work done per unit of charge against a static electric field to move the test charge between two points. It is <span>an electromotive force and also referred to as potential difference. Voltage is expressed in volts. (V). from the given explanations the following is true:</span>
<span>It is the difference in electrical potential energy between two places in an electric field.</span>
Answer:

Explanation:
As we know that the energy stored in the capacitor is given as

here we know that

also we know that

now we have


now we know the formula of capacitance



The correct answer for the question that is being presented above is this one: "A) self-sustaining." The term that <span>best describes a chain reaction associated with a nuclear reaction is self-sustaining.</span>
Here are the following choices:
<span>A) self-sustaining
B) weak
C) non-explosive</span>
Answer:
No, it is not fair because they could overdo it and get injured and others may not have it.
The 2nd Law of Motion states acceleration is produced when a n unbalanced force acts on an object (mass) The more mass the object has the more net force has to be used to move it.
Examples:
If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
It's easier to push a empty shopping cart then a full one, because the full one has more mass than the empty one. This means more force is required to push the full shopping cart.
