Answer:
the speed of the wave on the string is 43.16 m/s
Explanation:
Given;
first harmonic of the wave formed by the string, f₀ = 26 Hz
length of the string, L = 0.83 m
The wavelength for first harmonic of the wave is calculated as;
L = N ----> N
L = λ₀/2
λ₀ = 2L
The speed of the wave on the string is calculated as follows;
v = f₀λ₀
v = f₀ x 2L
v = 26 x 2 x 0.83
v = 43.16 m/s
Therefore, the speed of the wave on the string is 43.16 m/s
Answer: The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system.
Explanation:
Answer:if youre looking for the weight of the thermas in genral it should be 500n
Explanation:using the formula w=mg
w=500x10
giving us 500 newtons which is the weight.
Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
It would be a bike that doesn't use an electric circuit.
