Any exercise that has very hight intensity or puts you at your maximum level of exertion is an example of anaerobic exercising. Anaerobic exercise is suppose to help you gain muscle and lose un-needed weight. Anaerobic means "without oxygen." This is when your breathing is so intense you have a few intense deep breaths of air but very little breaths in all. This will happen when lifting weights, running, or sprinting up the stairs.

Answer: 0.9
Explanation:
If frequency equals the amount of oscillations in one second then 20/18 = f = 1.11 and to find period (T) then we use the equation T= 1/f or in this case 1/1.11 = 0.9
F- force on the object,
m - mass of the object:
F = 12 N = 12 kgm/s², m = 2 kg
F = m · a
a = F : m = 12 N : 2 kg = 6 m/s²
