When a car collides with a truck, intuitively the car reacts more during the collision. (You’d rather be riding in the truck!) So occupants in the car would feel the bigger force. In the meantime, Newton’s 3rd law states: The force exerted by object A on object B is equal in strength (but opposite in direction) to the force exerted by object B on object A. How would you reconcile the law with the collision feeling?

Aparticle moves in a circle 1.50 m in radius . through what angle in radians does it rotate if it moves through an arc length of 2.50m? what is the angle in degrees?

Which component of the earth’s atmosphere is decreased due to photosynthesis?

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
