Answer:
Explanation:
Force on a current carrying rod due to magnetic field is given as
here we know that
current in the rod
now magnetic force is balanced by the weight of the rod
so we will have
0.14 Hours........... or 8.4 minutes........ or 504 seconds
Answer:
2763.53411 m/s
Explanation:
M = Mass of Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
= Launch velocity
= Final velocity = 500 m/s
h = Altitude = 400 km
m = Mass of satellite
As the energy of the system is conserved we have
The launch speed of the satellite should be 2763.53411 m/s
