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 .

Much of the energy of falling water in a waterfall is converted into heat. If all the mechanical energy is converted into heat t

Assoli18 [71]

Answer:

Explanation:

potential energy of water is converted into heat energy

P E = mgh = m x 9.8 x 111

= 1087.8 m .

Let rise in temperature θ

m x s x θ = heat absorbed

m x s x θ = 1087.8 m

m x 4182 x θ = 1087.8 m

θ = 0.26 degree celsius .

A lighthouse is located on a small island 5 km away from the nearest point p on a straight shoreline and its light makes two rev

lisabon 2012 [21]

The distance starting from the point to the lighthouse would be regarded as the hypotenuse.

And also will be the radius of the circle the beam of light is generating at that point.

So get the radius first

r = sqrt (1^2 + 5^2)

r = 5.099 km

find the circumference:

C = 2*pi * 5.099 km

C = 2 * 16.01898094

C = 32.04 km

Then find the speed in km/sec

One revolution: 60/2 = 30 sec per revolution

Speed = 32.04 km/30 sec

S = 1.068 km/sec is the speed of light
