What is the maximum voltage that can be applied to this capacitor without causing dielectric breakdown?

1 answer:

8 0

Here is the answer. The maximum voltage that can be applied to this capacitor without causing dielectric breakdown is 7170 VOLTS. 3e6 v/m x 0.00239 m = 7170 volts. I had to look for the other details to know what you are referring to. Hope this answers your question. Have a great day!

How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters

KatRina [158]

Answer:

The work done is 2800 Joules

Explanation:

When a force causes a body to move, work is being done on the object

by the force

Work is the measure of energy transfer when a force moves an object

through a distance

→ Work = Force × Distance

→ The SI unit for work is the joule (J)

A refrigerator of 700 N is lifted straight up a distance of 4 meters

We need to find the work done

→ The weight of the refrigerator is 700 N

→ The force = 700 Newtons

→ The refrigerator is lifted straight up 4 m

→ The distance = 4 meters

Substitute these values in the rule below

→ Work = Force × Distance

→ Work = 700 × 4 = 2800 Joules

The work done is 2800 Joules

Tracy makes a list of energy transformations that occur as an engine runs to power a car. 1. chemical energy transforms into the

alex41 [277]

Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.

<h3> What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

Transformations that occur as an engine runs to power a car is;

1. Chemical energy of fuel transforms into thermal energy.

2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.

3. Thermal energy transforms into kinetic energy to help to run the car.

Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.

Hence, transformation 3 should Tracy removed from the list.

What are some ways scientists can study the seafloor?

TiliK225 [7]

Answer: A device records the time it takes sound waves to travel from the surface to the ocean floor and back again. Sound waves travel through water at a known speed. Once scientists know the travel time of the wave, they can calculate the distance to the ocean floor.

ou have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weight 3,

Dimas [21]

So far, since you moved into the apartment until the end of this much of the story, you haven't done ANY work on the dresser yet.

I'll admit that you pushed, groaned and grunted, sweated and strained plenty. You're physically and mentally exhausted, you're not interested in the dresser at the moment, and right now you just want to snappa cappa brew, crash on the couch, and watch cartoons on TV. But if you've done your Physics homework, you know you haven't technically done any work yet.

In Physics, "Work" is the product of Force times Distance.

Since the dresser hasn't budged yet, the Distahce is zero. So no matter how great the Force may be, it's multiplied by zero, so the Work is zero.
