Aspeeding car collides with a wall (attached to earth). consider the car-earth system to be isolated. a loud sound is produced in the collision, and the car is deformed. what can you say about the momentum of the car-earth system in this case?

Oxygen and nutrients are moved through the body by the: a. circulatory system c. lymphatic system b. digestive system d. reproductive system

The slope of a velocity time graph over any interval of time gives the during that interval

(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?
