The formula for the potential energy, EP is given by
EP = m × g × h
where:
m is the mass in kilograms
g is the gravity (9.8 m/s²)
h is the height in meters
EP = 6 × 9.8 × 2 = 117.6 kg-m²/s²
Answer:
When a ray of light falls on a glass slab normally, the angle between normal and incident ray is zero.
The voltage across an inductor ' L ' is
V = L · dI/dt .
I(t) = I(max) sin(ωt)
dI/dt = I(max) ω cos(ωt)
V = L · ω · I(max) cos(ωt)
L = 1.34 x 10⁻² H
ω = 2π · 60 = 377 /sec
I(max) = 4.80 A
V = L · ω · I(max) cos(ωt)
V = (1.34 x 10⁻² H) · (377 / sec) · (4.8 A) · cos(377 t)
<em>V = 24.25 cos(377 t)</em>
V is an AC voltage with peak value of 24.25 volts and frequency = 60 Hz.
When atoms bond together they make molecules.
