Answer:

No

Explanation:

It will never decay to zero

after one half life there is 1/2 left

  after the next half life thee is   1/2 * 1/2 = 1/4 left

     then 1/8th    then  1/16 th   then   1/32     1/64     1/128 ........to infinity  

        while htere is a VERY small amount left , there will never be ZERO left

A 1,492.3-kg airplane travels down the runway. Each of its four engines provides a force of
Fittoniya [83]

The acceleration of the air plane is 3.879 \mathrm{m} / \mathrm{s}^{2}

<u>Explanation:</u>

Given:

The mass of the air plane = 1492.3 kg

Force of each four engine = 1447.5 N

So, the total force of four engines can be calculated as = 4(1447.5) = 5790 N

The force that acts on the object is equal to the product of mass (m) and its acceleration. It can express by the below formula,

                         \text {Force }(F)=m \times \text { acceleration }(a)

The above equation can be written as below to find acceleration,

                        a=\frac{F}{m}

Now. Substitute the given values, we get,

                        a=\frac{5790}{1492.3}=3.879 \mathrm{m} / \mathrm{s}^{2}
