An earthquake is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's crust that creates seismic waves.
Carbon dioxide is released. Here is a diagram...
Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.
The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.
From the following expression
Speed = Distance/Time
Distance = Speed*Time
More on the kinetic Energy
Following from the given problem truck B will also have more kinetic energy because it velocity is more
Formula
KE= 1/2mv^2
Hence the more the velocity for a constant mass the greater the Kinetic energy

Answer: The question is incorrect, below is the correct question
Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?
The correct answer to the question is option D
mtDNA (mitochondrial DNA) analysis
Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.
There are several methods of DNA fingerprinting as outlined in the options given with the question.
In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.
