Air pressure ''Decreases'' with Elevation. So B) would be your answer.
Answer:
KE=2.3 x 10⁻¹⁹ J
Explanation:
Given that
λ = 544 nm
λ' = 485 nm
The kinetic energy KE given as
KE= E - Ф
Where
h= 6.626 x 10⁻³⁴
C=3 x 10⁸ m/s
Now by putting the values
KE=2.3 x 10⁻¹⁹ J
This is kinetic energy.
No, the car travels 1 metre in 5s at the start which is 0.2m/s, while the second meter it travels one metre in 8 seconds which is 0.125 m/s, the speed changes therefore it is not constant during the two metres the car travels
Answer:
Explanation:
Using Snell's law which is represented by
Making 
the subject of the formula then
Here 
and are the angles of incidence and refraction in water and air respectively
and 
are refraction index
Substituting 1.0003 for and 1.33 for then 
for 
we obtain
