Answer:
Find The area and calculate pressure.
Explanation:
Explanation:
T=1/f
So if frequency increases the period will decrease
A man inside an insulated metallic cage does not receive shock when the cage is highly charged because the whole charge reside on outer surface of the cage.
If the cage was a non-conductive cage, then the current cannot pass through the cage so it cannot affect the person in the cage.
For example- If you are seated in a car (metal body) and the car is hit with lightning, it is very unlikely that the person in the car would be hit with the lightning.
Answer:
7900N
Explanation:
35cm = 0.35m
When the object is at the rope center, its position at 3.44 / 2 =1.72m. We can find out the angle that the sagged rope makes with the horizontal
this means the rope makes with the vertical an angel of
90 - 11.5= = 78.5 degree
The tension of the 2 ropes, T, should balance with the object weight
= \frac{3160}{2*0.2} = 7900N[/tex]
E = I R
Voltage = (current)×(resistance).
V = 5A x 5 ohms = 25 volts.
