Answer:

The capacitance of the other capacitor is 1333.3 pF.

Explanation:

C' = 200 pF, V' = 100 V, C'' , V''= 0

Common potential, V = 60 V

Use the formula of the common  potential

V = \frac{C' V' + C'' + V''}{C'+ C''}\\\\60 = \frac{200\times 100 + 0}{200 + C''}\\\\1200+ 6 C''= 2000\\\\C'' = 1333.3 pF

The repulsive force between two protons has a magnitude of 2.00 N. What is the distance between them?
Aloiza [94]

Answer:

The answer to your question is letter A.     r = 1.07 x 10⁻¹⁴ m

Explanation:

Data

F = 2 N

d = ?

q = 1.6 x 10 ⁻¹⁹ C

k = 8.987 Nm²/C²

Formula

                 F = K\frac{q1q2}{r^{2}}

Solve for r

                r = \sqrt{\frac{kq1q2}{F}}

Substitution

                r = \sqrt{\frac{8.987 x 10^{9}x1.6 x 10^{-19} x 1.6 x 10x^{-19}}{2}}

Simplification

                r = \sqrt{\frac{2.3 x 10^{-28}}{2}}

                r = \sqrt{1.15 x 10^{-24}}

Result

                r = 1.07 x 10⁻¹⁴ m

vaieri [72.5K]

Answer:

Explanation:

Speed = distance / time

Velocity  = displacement / time

So ,

Speed = 50 km / 0.5 hr = 100 km/h

Velocity  = 40 km / 0.5hr = 80 km/h
