Answer:
(D) Car A is not accelerating, but car B is accelerating.
Explanation:
(1.5 m^3) • (1.05 kg/m^3) = 1.575 kg. That's quite a bag you've got there ! 1 m^3 is like 264 gallons of blood. Hope the poor patient survives the transfusion.
Also, the actual density of blood is around 1.05 g/cm^3, or 1050 kg/m^3.
The blood they're giving the guy in this question is about 18% less dense than the AIR in his hospital room, and they're pumping 264 gallons of it into him. Maybe THAT'S his whole problem.
That's a velocity.
It has a speed and the direction of the speed.
Answer:
Zero Acceleration.
Explanation:
If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.
Answer:
D, using a spring scale to exert a force on the block. Measure the acceleration of the block and the applied force
Explanation:
For this you would use the net force equation acceleration=net force * mass however you will want to isolate mass so it would be acceleration/ net force to get mass. Then process of elimination comes to play.
