Answer:
Explanation:
height, h = 125 miles = 125 x 1609 m = 201125 m = 0.2 x 10^6 m
Rdaius, R = 2.44 x 10^6 m
Mass, M = 3.3 x 10^23 kg
Let vo be the orbital speed.
The formula for the orbital speed is given by
where, M is the mass of mercury, R be the radius of mercury
vo = 2887.47 m/s
Time period, T = 2π(R+h) / vo
T = 2 x 3.14 x 2.64 x 10^6 / 2887.47
T = 5741.77 seconds
T = 1.6 hours
Explanation:
The scanner records the time from when a ultrasound wave is emitted to when its reflection is received. A technician calculates the depth of the reflection using the equation as :
The distance covered by ultrasonic wave when it was emitted and gets reflected is 2d. Speed is given by :
d is distance and t is time
Here, d = 2d
So, the factor of (1/2) is used because the distance covered by the wave is 2 times when it was emitted and received.
