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

After fertilization in the fallopian tube, It will take 6-12 days for the zygote to travel before arriving at the uterus.
<h3>What is a zygote?</h3>
A zygote is, generally speaking, a cell created by the fusion of two gametes; the growing person is created from such a cell.
It takes the zygote around 6–12 days following fertilization in the fallopian tube for the fertilized egg to travel to the uterus and attach to the uterus, a process known as implantation.
Hence It will take 6-12 days for the zygote to travel before arriving at the uterus.

Answer:
When an object vibrates, it causes the molecules in the air around it to move. These molecules collide with nearby molecules, forcing them to vibrate as well. As a result, they collide with more surrounding air molecules.
