What is the potential difference between the plates of a 3.7-f capacitor that stores sufficient energy to operate a 75.0-w light

Elena L [17]

The potential difference between the plates will be 1552 Volts.

<h3>What is a potential difference?</h3>

Voltage, or the difference in electric potential between two points, is defined as the amount of labor per unit of charge needed to move a test charge between the two points.

Given that a 3.7-f capacitor that stores sufficient energy to operate a 75.0-w

The potential difference will be calculated by the formula below:-

Q = I t

Where I = charge / time

Q = V * C

V C = I t

V = I t / C

V = 75 C/s x 60 sec / 2.9 faraday

V = 1552 Volts

A small barge is being used to transport trucks across a river. If the barge is 10.00 m long by 8.00 m wide and sinks an additio

Step2247 [10]

Answer: Weight truck+load = 29.4× $10^{3}$ N

Explanation: When an object floats in a fluid, there is an upward force, caused by the liquid, acting on the object that opposes the weight of the immersed object. This force is called <u>Buyoyant</u> <u>Force</u> and is determined by:

B = d*V*g

where

d is density of the fluid;

V is volume of liquid displaced due to the immersed object;

g is acceleration due to gravity;

For the truck, the system is in equilibrium, which means buyoyant force is equal weight. Then:

Volume displaced is

V = 10*8*0.0375

V = 3 $m^{3}$

Density of water: 1000kg/ $m^{3}$

$F_{P} = F_{B}$

$F_{P}$ = 1000*3*9.8

$F_{P}$ = 29.4× $10^{3}$ N

The weight of the truck and the load is 29.4× $10^{3}$ Newtons

On planet X, an object weighs 7.04 N. Onplanet B where the magnitude of the free-fallacceleration is 1.91g(whereg= 9.8 m/s2isthe

timurjin [86]

<h2>Mass of object in Earth is 1.37 kg</h2>

Explanation:

On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.

We have

Weight = Mass x Acceleration due to gravity

On planet B

25.74 = Mass x 1.91 g

25.74 = Mass x 1.91 x 9.81

Mass = 1.37 kg

Mass is constant for an object. It will not change with location.

Mass of object in Earth = Mass of object in Planet B

Mass of object in Earth = 1.37 kg
