Answer: C ) 75 kilometers
Explanation: 30 + 45 = 75
Answer:
The wave in the string travels with a speed of 528.1 m/s
Explanation:
Wave speed of sound waves in a string, v, is related to the Tension in the string, T, and the mass per unit length, μ, by the relation,
v = √(T/μ)
μ = 5.20 × 10⁻³ kg/m
T = 1450N
v = √(1450/0.0052) = 528.1 m/s
Hope this Helps!!!
Well i think the answer is impossible to find because there is no picture
Answer:
Because a person may be pulled in the direction of the moving train. Thereby causing accident
Explanation:
According to Daniel Bernoulli's theorem, he was widely known as a Mathematician. He stated that due to the higher velocity of a moving train, there is higher kinetic energy in terms of volume around it, while the air pressure between the person and the train becomes lower.
As a result, a person near a moving train may be pulled in the direction of the moving train. Thereby causing accidents that may lead to death.
Well you have to think of it like electricity go through your answer closes to that and figure it out
