Answer:
A. 4.5 x 10^-5 kg.m2
B. 108 x 10^-3 kg.m2
C. 54 x 10^-5
Explanation:
A. I = m(r^2)
point mass m = 0.005 g = 5 x 10^-6 kg
I = (5 x 10^-6 kg) x (3 m)^2 = (5 x 10^-6 kg) x 9 m^2 = 4.5 x 10^-5 kg.m2
B. I = m(r^2)
point mass m = 0.3 kg = 3 x 10^-1 kg
I = (3 x 10^-1 kg) x (0.6 m)^2 = (3 x 10^-1 kg) x 0.36 m^2 = 108 x 10^-3 kg.m2
C. KE = 1/2I(w^2)
KE = 1/2(3 x 10^-2 kg.m^2)(0.6 rad/s)^2 = 54 x 10^-5
Answer:
None of the them has a complete answer
.
Explanation:
The current in a wire is a function of the conduction element geometry inside the cable, given by the resistance and the conduction area. So saying twisted/shield, is not giving us any information about the current rating of the wire.
Repairs to the wire may affect the area of the conductor, reducing the effective surface of conduction. But a well-executed repairing must made an insignificant change in the resistance. So it's not a definitive concept.
A twisted/shield wire is generally used for signal transport, as it's configured to reduce the noise in the data transmission.
Answer:

Explanation:
Answer:
Speed of sound is 30.91m/s
Explanation:
Speed is given by:
Speed = distance travelled / time taken
Given:
Distance travelled = 1020m
Time taken = 33seconds
Speed = 1020m/33s
Speed = 30.91m/s
