Question
There are two capacitors of values 50 mu F and 22 mu F. What is the total capacitance if they are connected in parallel ___________ and in series _____________. Images in which no light rays pass directly through are referred to as ___________ images. The magnetic field surrounding a magnet points from ____________. East-West North-South South-North West-East What is the angular frequency of a wave with a wavelength of 75 times 10^-9 m? ____________ A negatively charged particle is traveling North through a magnetic field that is pointing directly up. What is the direction of the magnetic force? __________ North South East West How many protons are in the atom Ba^137? ___________Explanation / Answer
(5) If they are connected in the parallel then the equivalent capacitance will be
C = C1 + C2 = 50 + 22 = 72 uF
If theyy are connected in series then
C = C1*C2 /(C1 + C2) = 50*22 / (50+22) = 15.278 uF
(6) If light rays can not pass through an image than it will be OPAQUE.
(7) The magnetic field around a magnet is from North to south.
(8) Angular frequency (w) = 2Pi*f
f = C/wavelength
where C is speed of light = 3*108 m/s
f = 3*108 / 75*10-9 = 4*1015
w = 2Pi*f = 2.513*1016 rad/s
