We should really talk about the energy of a photon.
Photon Energy= h x c/ wavelength
where h is Planck's constant and c is the speed of light
h = 6.63 x 10^-34
c =3x 10^8
Energy = 2.37 x 10^-21
Answer:
a) 43.20V
b) 2.71W/s
c) 40.25s
d) 7.77Nm
Explanation:
(a) The emf of a rotating coil with N turns is given by:
N: turns
B: magnitude of the magnetic field
A: area
w: angular velocity
the emf max is given by:
(b) the maximum rate of change of the magnetic flux is given by:
(c)
(d) The torque is given by:
3 hours, because for every 50 km equals one hour 150 divided into 50 equals 3
Hi there!
To find the final velocity of an object dropped from rest, we can used the simplified equation:
vf = √2gh
Plug in the given values: (g = 9.8 m/s²)
vf = √2(9.8)(100) ≈ 44.272 m/s
