To solve this problem we will apply the energy conservation theorem for which the work applied on a body must be equivalent to the kinetic energy of this (or vice versa) therefore
Here,
m = mass
= Velocity (Final and initial)
First case) When the particle goes from 10m/s to 20m/s
Second case) When the particle goes from 20m/s to 30m/s
As the mass of the particle is the same, we conclude that more energy is required in the second case than in the first, therefore the correct answer is A.
The startling answer is:
The bacteria ate the agar and reproduced (made more bacteria). There are so many of them now that you can see the blob of them.
I believe the correct answer from the choices listed above is the last option. The advances in food production that were attributed to the Green Revolution of the 1960s and 1970s are drought-resistant varieties of crop plants.
Hope this answers the question. Have a nice day.
