Potential energy U = mgh
Given h = 123 m,
mg = F = 780 N
Then
U = (123)(780)
= 95940
= 9.59 x 10^4
Sodium (Na) is a Alkali metal so that's the answer
Answer:
466.956 J
Explanation:
potential energy = mass x gravitational field(9.81) x height
Answer:
962.5 Hz
Explanation:
given,
frequency = 8.94 GHz
speed of the trap = 32.3 m/s
frequency shift = ?
frequency of shift is calculated using formula
c is the speed of light
f_o is the frequency of the radar gun
the frequency of shift is equal to 962.5 Hz
