Of course steady state condition occurs in almost any system but time it will occurs varies among system. for this kind of system, conduction, steady state conduction occurs when the temperature change from one point to the point is already constant. steady state is not achieved immediately because the heat travels and material will not be heated at the same way at the starting point.
Answer:
1974.4328 m/s²
Explanation:
r = Radius = 0.5 m
t = Time taken = 0.1 second
Rotational speed
The centripetal acceleration is given by
The centripetal acceleration of the rock is 1974.4328 m/s²
Frequency and wavelength are inversely related. That is, when frequency increases, the value of the wavelength decreases and vice versa. The constant of proportionality of the relation is the speed of light that has a value of 3.0x10^8 m/s. We calculate as follows:
wavelength = speed of light /frequency
488x10^-9 = 3.8x10^8 / frequency
frequency = 6.15x10^14 /s = 6.15x10^14 Hz ------> OPTION 3
Answer:
The law of conservation of energy is the preserved form of energy.
Option (1) is correct that is the total amount of energy in the universe remains constant.Because energy is conserved.
Option (3) is correct since, it is conserved so, it can not be created or destroyed.
Option (4) Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.
Option (5) is correct because in closed, isolated system energy is conserved.
