The graph represents 2 cars traveling along the same straight road. Which car has the greatest velocity? Why ? The red car has the greatest velocity because its line has the steepest slope.
O The blue car has the greatest velocity because its slope is more horizontal.
The red car has the greatest velocity because it traveled the greatest distance in the most time-
O The blue car has the greatest velocity The blue car has the greatest velocity because it was moving forward the
entire 10 second period.

How much work would a child do while puling a 12-kg wagon a distance of 3m with a 22 n force directed 30 degrees with respect to the horizontal? (a) 82j (b) 52j (c) 109j (d) 95j

What are the theoretical properties of a gas at a temperature of 0 kelvin?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
