Two identical trucks, having the same mass, are traveling down a long straight flat road at constant speeds. However, Truck A has a greater speed than Truck B. Truck A has a greater ___.

Momentum

Explanation:

Truck A has a greater momentum compared to Truck B.

Momentum is the product of mass and velocity of a body;

     Momentum = mass x velocity

We see that the body with more mass and velocity will have a higher momentum.

Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
