Frequency = velocity/wavelength
Frequency = 10/20
Frequency = 0.5 Hz
It should be a metamorphic rock as those rocks are formed due fue to heat and pressure
Answer:
A) 0.44 rad/s
B) 3.091 rad/s
Explanation:
Initial angular momentum must be equal to final angular momentum.
W1 = 0.80 rad/s
I = 1360 kgm^2
Initial moment Iw = 0.8 x 1360 = 1088 rad-kg-m^2/s
For second case
I = (65 x 4)4.2 + 1360 = 2452 kg-m2-rad/s
New momentum = 2452 x W2
Where w2 = final angular momentum
= 2452W2
Equating both moment,
1088 = 2452W2
W2 = 0.44 rad/s0
If they were on it before,
Initial momentum
I = 1360 - (60 x 4)4.2
= 352 rad-kg-m^2/s
352W1 = 1088
W1 = 3.091 rad/s
