1. ### how can we find our weight with the help pf centripetal force formula?

centripetal force=ma (f=ma;newton's 2nd law) when you know the force and radial acceleration you can find the mass. mass*gravity=weight

2. ### Suppose a resistor of 10 ohms, a capacitor of 820 pF, and a coil of 10 microHenry are in parallel.?

There are (3) devices here of which (2) are frequency dependant; the capacitor and the inductor. The capacative reactance Xc = 1 / (2 * pi * Freq * C ) = 1 / (2 * pi * 10E6 * 820E-12) = 194.0914 ohms or -j194.0914 as a phasor. The...

5. ### A 13.1 V battery is connected to a 4.2 pF parallel-plate capacitor.... Help?

C = Q/V => Q = CV = 4.2 x 10^(-12) * 13.1 C = 5.502 x 10^(-11) C.

6. ### A voltage of 12 V is placed on a capacitor with C=100 pF(picofarads). a)What is the charge on the capacitor?

The Formula is: Q = C x U (Q in Coulomb) so a) charge Q = 100 x 12 = 1200 picoCoulombs = 1.2 micro-Coulombs The potential difference V = q/C requires the work dW = dV...

7. ### What is the type of relationship pf a graph when it doesn't pass through the origin?

1) We have a linear relationship between the two quantities. Since it doesn't go through the line it has an offset or a bias from direct proportionality. 2) We have a situation where the change of a quantity is directly proportional to the change of the other. y = mx, then y is directly...
