Linear expansivity is a type of thermal expansion. It is described by a fraction that represents the fractional increase in length of a thin beam of a material exposed to a temperature increase of one degree Celsius. ... Linear expansivity is used in many real world applications.
I think you have them all marked correctly
7. They carry hereditary material from parent
8. 50 percent

If Im wrong Im sorry. its been like 4 years since i took biology but i remember some things
K.E = 1/2mv^2
The kinetic energy is 50,000 J and the mass of the car is 10,000 kg.
50,000 J = 1/2(10,000kg)v^2
Solve for v (velocity)
50,000 J = 5,000 kg x v^2
10 = v^2
about 3 m/s (in terms of significant figures)
