Answer:
(a) Radius of orbit will be
(b) Earth gravitational force will be
(C) Height will be
Explanation:
We have given
Mass of the earth,
Mass of the satellite, m = 5600 kg
Radius of earth,
Time period T = 6200 sec
We know that
Now
(a) We know that
Radius of the orbit
(b)
Force
(c)
Altitude
Answer:
In an electromagnetic wave in free space, the ratio of the magnitudes of electric and magnetic field vectors E and B is equal: <u>speed of light(c) </u>
Explanation:
Generally the ratio of the E(electric field ) and the B(magnetic field ) is equal to the speed of the electromagnetic wave i.e the speed of light (c) the value is
The answer would be b 0.84
The initial temperature of the bar is 25. To get to the t temperature you need to add (t-25) degrees Celsius.
for 1 degree................... 7 Joules
y given degree........ p Joules
p=7y
In our case y=(t-25) .
h(t) = 7(t-25) which is the final answer.
