When you divide 6x10^24 by 8x10^8 you end up with
This simplifies to
Now this number is not written in scientific notation as it does not have its first digit before the decimal, so we must move the decimal of this one to the right.
To do that you must multiply the number by 10.
This means that the exponet of 10 must decrease by 1.
This makes the answer
Answer:
Factor by which kinetic energy increase = 4 times
Step-by-step explanation:
Given,
= 15.64 m/s
Initial kinetic energy of the car is given by,
= 183606.46 J
= 31.29 m/s
So, final kinetic energy of car is given by
= 734425.84 J
Now, the ratio of final to initial kinetic energy can be given by,
Hence, the kinetic energy will increase by 4 times.
