The sun is bright and when its cold there is no sun
Depends how high the cliff is. The longer the drop, the faster you’ll go. Since the fall was 4.2 seconds he wouldn’t be going too too fast
Given :
A wooden block is let go from a height of 5.80 m.
To Find :
The velocity of the block just before it hits the ground.
Solution :
We know, by equation of motion :
Here, a = g = 9.8 m/s²( Acceleration due to gravity )
Putting all given values in above equation, we get :
Hence, this is the required solution.
Sound and light, as well as all other types of mechanical and electromagnetic
radiation, travel as waves. They all carry energy from place to place.
Answer:
300 K
37.5 K
Explanation:
= Boltzmann constant =
T = Absolute temperature
= Mass of Helium atom = 4 u
= Mass of Oxygen atom = 32 u
The kinetic energy of a gas is given by
So, the temperature would be 300 K
RMS velocity is given by
The gas temperature is 37.5 K
