Answer:
A
Explanation:
You have to give energy away for B. You have to think about that carefully. The CO2 starts out with a great deal of energy (mostly KE) and has to slow down to go from gas to a solid. Not B
In general C is the same way. Water has more energy than ice. Not C
Same principle in D. Not D.
So it's A
Answer:
Explanation:
frequency of radiation
= 8.54 x 10¹⁴
wave length = 3 x 10⁸ / 8.54 x 10¹⁴
= .3513 x 10⁻⁶ m
= 3513 A
Energy of this wave OR energy of each photon in eV
= 12375 / 3513
= 3.52 eV
the minimum amount of energy required = 3.52 eV.
Claudia's mass is 51 kg, therefore her weight is
W = (51 kg)*(9.8 m/s) = 499.8 N
The bungee cord extends by x = 5m due to the weight.
By definition the spring constant for the bungee cord is
k = W/x = (499.8 N)/(5 m) = 99.96 N/m
Answer: The spring constant is 100 N/m (nearest tenth)
It is made like the reflect in presence of magnetism. It gets deflected on earth towards north also because of a huge magnetism of earth.
