Answer:
the extension would be less the new extension might be 3 cm
Explanation:
Answer: Transverse wave
Explanation:
This type of wave is transverse wave. Transverse wave is a wave that occurs when the vibration of the medium is perpendicular to the direction of the wave. According to the question, the crowd were standing vertically but they were arranged in the stadium in the horizontal manner.
Answer:
63N, 45N
Explanation:
Given:
Tension 1 = T1
We have the following free body equations:
F - T1 = 100*0.3 -(I)
T1 - T2 = 60*0.3 -(II)
T2 = 150*0.3 -(III)
Adding the three above equations, we have
F - T1 + T1 - T2 + T2 = (100*0.3) + (60*0.3) + (150*0.3)
Hence, F = 93N
Hence, substituting into equation I we have
T1 = Force by bar on lighter cart = 93 - (100*0.3) = 63N
Hence, force that heavier cart exerts on bar
T2 = 150*0.3 = 45N
Answer:
B is the answer for the question
