60 N net force is applied to a 12 KG box. What is the acceleration of the box?
galben [10]

Answer:

The answer is

<h2>5 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and it's net force can be found by using the formula

acceleration =  \frac{force}{mass}  \\

From the question

force = 60 N

mass = 12 kg

So we have

acceleration =  \frac{60}{12}  \\

We have the final answer as

<h3>5 m/s²</h3>

Hope this helps you

Question 4 of 33
Alex777 [14]

Oils like petrol and diesel are fossil fuels. Using oil can be at a disadvantage as spilled oil can harm wildlife and the environment. Thus, option c is correct.

<h3>Why is oil harmful?</h3>

Oil is a nonrenewable fossil fuel that can get depleted when used in excess. It is extracted by many processes through mining underwater and in fields. During these extraction processes, oil spills can occur.

Oil spills directly affect the environment and cause pollution of water and soil. This leakage affects the flora and the fauna that lives in the area and causes their death due to lack of oxygen.

Therefore, option c. oil spills cause harm to wildlife.
