What happens to a light wave that travels through glass and strikes a boundary with water at a 45° angle?
A. It refracts in the water, away from the boundary.
B. It reflects back into the glass in the direction it was traveling from.
c. It refracts in the water, toward the boundary.
D. It reflects back into the glass with a 45° angle of reflection.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
