First we calculate the
effective radius R:
R = 1740+94 = 1834 km =
1.834E6 m
Then taking the mass of
the moon:<span>
M = mass of moon = 7.348E22 kg </span>
We then calculate the
period using the formula:<span>
<span>T = 2π√[R³/(GM)] = 7049.3 sec = 1.96 hr</span></span>
Answer:
Explanation:
The magnetic field is pointing upwards , so magnetic flux is upwards . Due to increase in area , magnetic flux in upward direction will increase . Hence according to Lenz's law , induced current will be such that it will try to counter this increase . It is possible if current is in clockwise direction . Due to it magnetic field will be induced in downward direction thus reducing the total magnetic flux.
Hence direction of induced current will be clockwise direction in the loop as shown in the image enclosed .
Answer:
Equation 2
Explanation:
Initial velocity ( Vo ) = 20 m/s
Acceleration ( a ) = 1.1 m/s^2
Distance ( d ) = 55 m
Final velocity ( Vi ) can be found using equation 2
Answer:the hose would explode and you would mess the water system out
Explanation:
Current pulled by these appliances is 10.25 A
Explanation:
- Step 1: Find the total power used by these appliances.
Total power = 240 + 30 + 720 + (2 × 120) = 1230 W
- Step 2: Given voltage is 120 V, find the current by using the formula Power = Voltage × Current
⇒ Current(I) = P/V = 1230/120 = 10.25 A
