The ultraviolet catastrophe was the prediction of late 19th century/early 20th century classical physics that an ideal black body (also blackbody) at thermal equilibrium will emit radiation in all frequency ranges, emitting more energy as the frequency increases.
Answer:
1) the unit of power is A.Watt
2)100J=50W
100=50s
divide both sides by 50s
S=2s(A)
An airplane is flying at a constant speed in a positive direction. It slows down when it approaches the airport where it's going to land. this is an example of negative acceleration (D).
Well, a curler uses heat to calm down friction so I am not sure
Answer:
F=12.5N
Explanation:
Net force = rate of change of momentum
so find the change of momentum P
Pdown
Pup
dP = change in P
so
