<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:
Acceleration, 
Explanation:
Given that,
Mass of Suzie, m = 76 kg
Initial speed of Suzie, u = 50 mph = 22.35 m/s
Finally, it stops, v = 0
Time, t = 1.2 s
Let a is the Suzie’s average acceleration. It is equal to the rate of change of velocity. Its formula is given by :
So, the average acceleration of Suzie’s is 
and she is decelerating. Hence, this is the required solution.
Answer:
They have very large gas Masses.
Explanation:
why is the pressure so high deep inside the outer planets?
The answer to this question is Gravity
Answer:
80 Joules.
Explanation:
Given that a 20 kg sled stars at the top of a hill which is 10 m above the bottom and slides a distance of 50 m, ending at the bottom of the hill with a speed of 8 m/s. During the slide, the work done by gravity is about ?
The parameters given are:
Mass M = 20 kg
Height h = 10 m
Velocity V = 8 m/s
The workdone by gravity will be equal to the total energy
At the bottom of the hill, the total energy will be equal to the maximum kinetic energy.
Maximum K.E = 1/2mv^2
K.E = 1/2 × 20 × 8
K.E = 80J
Therefore, the workdone by the gravity is equal to 80 Joules.
