The Ice and steam points of a certain thermometer are found to be 20 cm apart. What temperatureis recorded in Celsius when the length of mercury theard is 5cm above the ice point mark?
20 g = 20 / 1000 = 0.02 kg.
Magnitude of momentum of the sparrow = mass * velocity
= 0.02 * 8.1
= 0.162 kg-m/s. (answer)
Answer: electromagnetic radiation
Explanation: range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths.
energy is the ability to do work while work is the dot product of force and displacement
Answer:
Explanation:
Mass of small disc = m
radius of small disc = r
Mass of large disc = M
Radius of large disc = R
Initial angular speed = ωi
Let the final angular speed is ωf
As no external torque of applied on the system so the angular system remains constant.
I1 ωi = I2 ωf
MR^2 ωi = (MR^2 + mr^2) ωf
