Answer:
(D) 3
Explanation:
The angular momentum is given by:
Thus, the magnitude of the angular momenta of both solar systems are given by:
where we have taken that both systems has the same radius.
By taking into account that T1=3T2, we have
but L1=L2=L:
Hence, the answer is (D) 3

Answer:
Explanation:
frequency of vibration
n = 40 / 22.3 per second.
= 1.794 per second
velocity of wave v = 369 / 13.5 cm / s
= 27.33 cm / s
wavelength = velocity / frequency
= 27.33 / 1.794
= 15.23 cm
So what the thermal energy equation tells you is the internal heat energy a system gives you due to the movement of particles/temperature. This heat is due to the kinetic energy in the particles. Q represents the heat transfer of a material that has a specific mass, m, specific heat, c, and some temperature or change in temperature, ΔT. For example, say you have an object of mass 1kg, specific heat 0.5J/kg°C and the temperature changes from 50°C to 100°C. To find the heat transfer you would use the equation Q= 1kg*0.5J/kg°C*(100°C-50°C). This would tell you that the heat transfer of this particle is 25J which means that 25J of energy are transferred from one point to the other in this system.
