Answer:
R = 60 Ω
Explanation:
given,
Potential of the certain device, V = 120 V
current rating of the circuit, I = 20 A
resistance of the device, R = ?
Using Ohm's Law
V = I R
R = 60 Ω
hence, the resistance of the device is equal to 60 Ω
Answer:
ratio of tangential velocity of satellite b and a will be 0.707
Explanation:
We have given distance of satellite B from satellite A is twice
So
Tangential speed of the satellite is given by
, G is gravitational constant. M is mass of satellite and r is distance from the earth
We have to find the ratio of tangential velocities of b and a
From the relation we can see that tangential velocity is inversely proportional to square root of distance from earth
So
So ratio of tangential velocity of satellite b and a will be 0.707
