Explanation:
It is given that,
Mass of an object, 
(a) Time period of oscillation, T = 2.4 s
The formula for the time period of spring is given by :
Where
k is the force constant
(b) Displacement in the spring, x = 2.2 m
Energy stored in the spring is given by :
Hence, this is the required solution.
A because its the only one that actually involves science
Calculating Average Atomic Mass<span>. The </span>average atomic mass of an element<span> is the sum of the </span>masses<span> of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of </span>atoms<span> of that </span>element<span> that are of a given isotope).</span>
D is the answer because your body can do that in all the 7 location where the heat goes in your body in 2,3, OR 5-6 days
53.3 km/h is the average amount of the car trip if 80km
