The property are on there hope this helps
Answer:
12.74 ms^-1 download
Explanation:
v=28.2, a=9.81
start from rest u=0
v=u+at=0+(9.81)t=28.2
t=2.875...
it reach 1.4 second before hitting the ground:
t=1.4, u=0, a=9.81
v=u+at=0+(9.81)(1.4)=12.74
Answer:
The value is
Explanation:
From the question we are told that
The temperature is
Generally the root mean square speed of the oxygen molecules is mathematically represented as
Here R is the gas constant with a value
M is the molar mass of oxygen molecule with value
So
=>
Answer: contain different amounts of energy
Explanation:
The energy of a photon is given by:
Where:
is the Planck constant
is the frequency of the light which is inversely related to the wavelength.
Now, if we have photons of different light waves, this means we have photons with different frequencies.
As the energy of the photon depends on its frequency:
Photons of different light waves <u>contain different amounts of energy.</u>
