Answer:
1 Hz
Explanation:
For rope fixed on both ends the length corresponds to λ/2 (λ is wavelength)\
Thus L = λ/2
=> λ = 16 m
We know that frequency and wavelength are related as
f x λ = v where f is frequency and v is speed of the wave
thus f = v/λ
f = 16/16 =1 Hz
Answer:
Q = 675 [J]
Explanation:
We can calculate the amount of heat transfer by means of the following expression that includes the mass and temperature change in a body as a function of the specific heat.
where:
m = mass = 25 [gr]
Cp = specific heat = 0.9 [J/g*°C]
Tinitial = 55 [°C]
Tfinal = 25 [°C]
![Q=25*0.9*(55-25)\\Q=675 [J]](https://tex.z-dn.net/?f=Q%3D25%2A0.9%2A%2855-25%29%5C%5CQ%3D675%20%5BJ%5D)
Answer:
lol
