Answer:
60 V
Explanation:
Let the potential on capacitor be V . This will be equal to voltage of the source .
During discharge this voltage of capacitor will create current .
V / 120 = .5
V = 60 V
So this would have been the voltage of the source . So voltage of source
= 60 V

Because of inertia (Newton's First Law), the person will keep moving forward with the same velocity that they were travelling before the collision. Also, following Darwin's Law of natural selection, it is a mechanism for removing undesirable traits (idiocy) from the human gene pool.
Answer:
<h2>
200m/min</h2>
Explanation:
The formula for calculating distance covered = Speed * time
If Maggie completed a 10000-m race at an average speed of 160
m/min, the the time taken by Maggie to complete the race will be expressed as;
Time = Distance/Speed
Time = 10000/160
Time = 62.5 minutes
If it took Tom 12.5 fewer minutes to complete the race, then the time taken by tom to finish the same race will be 62.5 - 12.5 = 50minutes.
To get Tom's average speed, we will use the same formula as above;
From Distance = Speed * Time
Speed = Distance/Time
Since both of them completed the same distance, distance covered by Tom is also 10000m
Tom's speed = 10000/50
Tom's speed = 200m/min
<em>Hence Tom's average speed is 200m/min</em>
Answer:
60 J
Explanation:
Given That
Coefficient of performance, CoP = 4.2
Quantity of heat of the refrigerator, Q = 250 J
Work done by the refrigerator, W = ?
First, it should be noted that the Coefficient of Performance can be said to be, the ratio of the Heat required to the Work done by the system. Mathematically written as,
CoP = Q / W
Since we are already given the values from our question, we can plug it in as it's a pretty straightforward question
4.2 = 250 / W, making W subject of formula, we have
W = 250 / 4.2
W = 60J
Thus, the Work done by the refrigerator is 60 J
