Because the people put in charge of defining SI units said so
Answer:

Explanation:
initial velocity
magnitude of velocity, v = 12 m/s
angle made of velocity with negative x-axis,θ = 60°
We need to calculate x- component of v

velocity is in negative x-direction, v = -12 m/s
now,



Hence, the velocity x-component is equal to -6 m/s.
Answer:
In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. ... Metalloids such as boron, silicon, and germanium are sometimes counted as nonmetals
Explanation:
Because you are moving down to up
Answer:
The truck and car have the same momentum.
Explanation:
= Mass of car = 
= Velocity of car = 
= Mass of truck = 
= Velocity of truck = 
Momentum of car

Momentum of the truck

Both the truck and car have the same momentum of
