Calculate the work done by a force of 30 N in lifting a load of 2 kg to a height of 10 m (g = 10 m/s2)
Mars2501 [29]

Answer:

<u>300 J</u>

Explanation:

Given :

  1. Applied force = 30 N
  2. Mass = 2 kg
  3. Height = 10 m
  4. g = 10 m/s²

Work done by the force :

  • Work done = Force x Displacement
  • Work done = mg x h
  • Work done = 30 N x 10 m
  • Work done = <u>300 J</u>

<u></u>

<u><em>Note</em></u> :

  • What you have calculated is the work done by gravitational force on the object (that too, incorrectly)
  • But in the end, it asks for work done by the force of 30N
  • Hence, the given answer ~

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!<br><br> Which number shows the wavelength?
Ray Of Light [21]

If you read the question carefully, you can find the answer right there in it.

In fact, you don't even have to read the whole question ... you only need to read one word.

In fact, you don't even have to read the whole word ... you only need to read part of the word.

The word to read is "wavelength".

The important part of the word is "length".

<em>Now</em> it's time to look at the picture:

#1 is a height.

#2 is a place on the wave

#4 is a place on the wave

<em>#3 </em>is the only thing in the picture that's a "length" of anything.

Which of the outer planets is MOST like Earth? How?
Over [174]

Answer:

It is not impossible to answer the question, my apologies for “discrediting” the answer it would have to be Venus, the outer planet most similar to earth.

Explanation:

Venus is very similar to earth, as many studies, research, factual intellectual based concepts - the size, shape, surface gravity, average density, mass, average days of 24 hours, season changes similar to earth, and tilted axis. As well as similar climate make Venus the most accurate answer.

Hope this helps! Thank you for your time.
