The order the boxes would land from slowest to quickest is A,C,B which is option C.
<h3>What is a Parachute?</h3>
This is a device used to slow the motion of an object through an atmosphere by creating drag.
The size of the parachute affects the speed of falling because a larger parachute allows it to displace more air, causing it to fall more slowly. The one with three parachutes which is A will fall slowest and the one with just one will fall fastest.

Answer:
light in the UV range.
Explanation:
Noble gases and halogens can combine to form lasers called Excimer, for this to happen the noble gas must be ionized with a high voltage discharge, thus forming a molecule of the type
noble gas (X) + halogen (H) → XH
This molecule is highly unstable and decomposes within a few nanoseconds, emitting light in the UV range.
Answer: 4
Explanation:
Given that:
Mass of car M = 2200 kg
Initial speed Vi = 50 km/hr
Final speed Vf = 100 km/hr
Kinetic energy is the energy possessed by a moving object. It is measured in joules, and depends on the mass (m) of the object and the speed (v) by which it moves
i.e K.E = 1/2MV^2
So, when traveling at 50 km/h
KE = 1/2x 2200kg x (50km/h)^2
KE = 0.5 x 2200 x 2500
KE1 = 2750000J
So, when traveling at 100 km/h
KE = 1/2x 2200 x (100 km/h)^2
KE = 0.5 x 2200 x 10000
KE2 = 11000000J
Thus, the number of times kinetic energy increases is obtained by dividing KE2 by KE1
i.e 11000000J / 2750000J
= 4
Thus, the kinetic energy from the car’s forward motion increase 4 times
