Answer:The human eye is sensitive to yellow-green light having a frequency of about 5.5*10^{14} ... What is the energy in joules of the photons associated with this light? ... As the wavelength and frequency of a wave are related, we can find the energy ... In order to find this value, we need Planck's Constant, h=6.626×10−34 J⋅s h ...
Explanation:
⬆️ I think it’s the one that goes up ( sorry if it’s wrong )
Answer:
320m/s
Explanation:
Step 1: State your values
s= NOT NEEDED
u=20m/s
v=?
a=10m/s²
t=30 seconds
Step 2: Find a suitable suvat equation:
v=u+at
Step 3:
subsitute values into equation:
?=20+(10x30)
20+300
320m/s
Answer:
the spring would be a constant of 10.5 m
