Answer:
the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius
I think it would be 10 m/s
Answer:
A. 2.30 x 10^2 kil
Explanation:
3/2 = 1.5 and 0.72/2 = 0.36
1.93 + 0.36 = 2.29
2.29 = about 2.30
A spring is an object that can be deformed by a force and then return to its original shape after the force is removed.Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar. Springs are an essential part of almost all moderately complex mechanical devices; from ball-point pens to racing car engines.
Answer
we know,

where
E = energy
h = planks constant
λ = wavelength
from the above equation, we can see that energy is inversely proportional to wavelength.

that is why
Violet color light has low wavelength but the energy of Violet light is very high whereas red light has low energy and high wavelength.
