If you are given force and distance, you can determine power if you know (2 points)

Physics
1 answer:
dangina [55]3 years ago
4 0

Answer:

The answer is time

Explanation:

So when youre given force and distance, you can determine work done

Work Done = Force × Distance travelled in the

direction of the force

Since Power = Work Done/ Time

when you know work done, and you want to find power, you will need time.

Because you have work done already, you dont need energy. Though you can use energy and time to find work too. The alternative formula for Power would be:

Power = Energy Converted/Time

A grating with 250 grooves mm is used with an incandescent light source. Assume the visible spectrum to range in wavelength from
NeTakaya

The number of orders that one can see the entire visible speed is 5 orders.

<h3>How to calculate the orders?</h3>

From the information given, it should be noted that the grating spacing will be:

d = (1.00 × 10^-4) / 250

d = 4000nm

Therefore, the number of times that are needed to complete the order will be the same as the number of orders which the long wavelength time will be visible. This will be:

= (4000 × sin 90°)/700

= 5.71

Therefore, the maximum orders will be 5.

A schematic can tell an electrician that the switches are normally
In-s [12.5K]

The correct answer is Option B) Open.

A schematic can tell an electrician that the switches are normally open

until the sensor senses smoke.

<h3>What is a schematic diagram?</h3>

A simple, understandable graphical representation of a plan or model is called a schematic diagram. Simple lines and symbols are used in schematics to convey details like what, how, and where. A schematic diagram's primary role is to highlight circuit components and the relationships between them. Schematics are a very useful tool for troubleshooting since they show which parts are connected in series or parallel and how.

An example of an electrical switch is one that is normally open. A typically open switch remains "off" when it is not compressed. The inside electrical connections are to blame for this. In a typically open switch, the contacts are open when the switch is off. This indicates that the switch is "off" because the electrical connection is damaged.

A 200 kg chunck of lead falls from a hight of 30m and smashes into a rigid floor. calculate the increse in internal engery
mr Goodwill [35]

Answer:

\Delta E=58800\ J

Explanation:

Given:

mass of lead chunk, m=200\ kg

height of the fall, h= 30\ m

  • Assuming the collision to be perfectly inelastic the whole kinetic energy of the chunk is lost after the collision.
  • Here when the chunk is at the given height it has a potential energy which on falling transforms into kinetic energy of the chunk.

So, increase in the internal energy of the system after the collision is :

\Delta E=m.g.h

\Delta E=200\times 9.8\times 30

\Delta E=58800\ J
