What has a larger capacitance, an aluminum sphere with a 10 cm diameter or one with a 100 cm diameter? Question 16 options: 10 c

creativ13 [48]

$\boxed{\sf C=\dfrac{Q}{V}}$

But

$\boxed{\sf \Delta V_{R_2\to R_1}={\displaystyle{\int}^{R_1}_{R_2}}dV=-{\displaystyle{\int}^{R_1}_{R_2}}\dfrac{kQ}{r^2}dR}$

Hence higher the radius lower the voltage
Lower the voltage higher the capacitance .

A very long stick ruled with meter markings is placed in empty space. A spaceship of rest length L = 100 m runs lengthwise along

alexira [117]

Answer:

Meter marks are on cut-off portion of stick is 100 - 60 = 40 m

Explanation:

Given data:

Spaceship length of L = 100 m

Relative velocity between the ship and stick is given as

$v = \frac{4}{5} c$

The observed length observed by the outside observer is

$L' = L\sqrt{1 -\frac{v^2}{c^2}}$

putting all value to get observe length

put $v = \frac{4}{5} c$

$L ' = 100\times \sqrt{1 - \frac{(4/5)^2c^2}{c^2}$

L' = 60 m

Meter marks are on cut-off portion of stick is 100 - 60 = 40 m

What flows in a circuit to generate a current?<br> A. Protons<br> B. Electrons<br> C. Neutrons

Alex_Xolod [135]

Answer B: Electrons

Explanation:
Protons and Neutrons stay inside (in the middle) of the molecule. Electrons move around, outside the molecule.

I hope this helps!!
