One food calorie is not 103 calories, rather, 1000 calories
Answer:
4.2 km
Explanation:
One food calorie is equal to 1000 calories and each calorie has 4.184 J hence for 617 food calories, the energy is equal to 617*1000*4.184
This energy is also given by mgh, the potential energy. M is the mass, g is acceleration due to gravity and h is height in metres.
Substituting 62.7 kg for m, 9.8 for g then
62.7*9.8h=617*1000*4.184
Answer:
(A-) Number of turns in secondary coil will be<u> less than 125.</u>
(B-) EXPLAIN- The voltage is to be lowered.<u> The voltage will be reduced from 120 to 9 volts.</u> As a result, a<u> step down transformer </u>will be used, indicating that the secondary coil's number of turns would be less than 125.
(C-)<u> The number of turns on the secondary coil is 12.5</u>
<u></u>
Explanation:
- STEP DOWN TRANSFORMER - A step-down transformer transforms high voltage (HV) and low current from the transformer's primary side to low voltage (LV) and high current on the secondary side. A phase down transformer is the opposite of this.
In electrical networks and transmission lines, a step-down transformer can be used in a number of ways.
<u>Step down transformer formula-</u>
We are given with the -
Primary voltage = 120V
Secondary voltage
Number of primary turns
- <u>To calculate the number of turns on the secondary coil -</u>
Since , the transformer ratio is given as -
So, the number of turns on the secondary coil is -
Putting , the given values -:
= 12.5
<u>Therefore , the number of turns on secondary coil is 12.5 .</u>
Answer:
B
Explanation:
That is solar energy and the sun will be releasing energy constantly for the rest of its life, meaning renewable
