Refraction is a phenomenon which results when a ray of light enters from one medium to another medium. When a ray of light enters from denser medium to rarer medium, it bends away from the normal. The laws of refraction are: The incident ray, the refracted ray and the normal all lie in the same plane.
The distance for any rectilinear motion at constant acceleration is:
d = v₀t + 0.5at²
where
v₀ is the initial velocity
So, if v₀ = 6v, and it stopped to 0 m/s, then the acceleration is equal to:
a = (0 - 6v)/t = -6v/t
Thus,
d = (6v)(t) + (0.5)(-6v/t)(t²)
d = 6vt - 3t
<span>d = 3t(2v - 1)</span>
Katherine paid $1.25 for a bottle of water
Explanation:
Given that,
Current of clothes dryer, I = 16 A
Voltage, V = 240 V
Time, t = 45 min = 2700 s
Current of personal computer, I' = 2.7 A
Voltage, V' = 120 C
Energy used by clothes dryer is given by :
Let t' is the time for this computer to "surf" the internet. Again using formula of energy used as :
So, for 8.83 hours you could use this computer to "surf" the internet.
