Certain series rlc circuit is composed of a 250 ? resistor, a 420 mh ductor (with negligible resistance), a 2.35-? f a .u-v (rms) sinusoidal voltage source. the source operates at a frequency of twice the resonance frequency for the 7.(11 points) a circuit. what is the average power delivered to the circuit from the source?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
