Work done by me for using force of 4 N to push an object 3 m away is 12 J.
<u>Explanation:</u>
Work done on any object is defined as the force required to displace that object from its original position. In other terms, the work done is the measure of force utilized for moving an object. So mathematically it is represented as the product of force with the displacement of the object due to that force.
Then, here it is given that force of about 4 N is used to displace the object to 3m. Thus,
So, 12 J of work is done by me to push an object 3 m away with the force of 4 N.
Answer:
Rachel needs 0.52 kg of fertilizer.
Explanation:
Since the surface is a <em>square</em> of 10 ft of size its area is A = 10 ft x 10 ft = 1.0 x 10² ft². <em>One third</em> of that space is devoted to tomatoes (<em>"space is divided equally among tomatoes, lettuce, and strawberries"</em>), that is, 1/3 x 100 ft² = 33 ft².
We calculate the kilograms of fertilizer required we need to know 2 equivalences:
1 ac = 43,560 ft²
1 lb = 0.4535 kg
Then, we can use proportions to find out the amount of fertilizer used:
If it goes from a volume of x, then when the volume is doubled it will go to a volume of 2x. If you meant what happens to the pressure, then the pressure halves as volume doubles due to Boyle's law.
Answer:
The last one is first, the first one is second, and the second one is third.
Explanation:
<h2><u>
Answer:</u></h2>
C: They should try to reproduce Dr. Maxwell's research to verify his results
<h2><u>
Why?</u></h2>
Other scientists may or may not agree to Dr. Maxwell, so they should test Dr. Maxwell's research again to see if his conclusion is true or not.
Hope this helps!
