D. 9/5 Kelvin
Answers
As you can see, if you put in some number of Celsuis C your answer is going to be multiplied by 5/9...meaning that 1°C = 5/9°F.
As for Kelvin, it's literally just Celsuis, but about 273.15° more.

1. First determine the suitable formula for this word problem. Which is a. A=vf-vi/t
Given are: Vf=99.2 km/h Vi= 0.0 km/h T= 4.0sec
Solution:
A= 99.2 km/h – 0.0km/h / 4.0 sec
A = 99.2 km/h / 4 sec
A = 2.8 km/h/sec
Answer:
24.8 km per second

Answer: Momentum is mass times velocity (P = m*v)
Explanation: Momentum is defined as the "amount of movement"
The momentum of an object moving can be calculated as:
P = m*v
where P is momentum
m is the mass of the object
v is the velocity of the object.
Notice that momentum has a given direction (the same of the velocity) so it is a vector.
Momentum is mass times velocity
