Study the image of two people pushing on opposing sides of a dog house at the same time. Compute the amount of force acting on the doghouse using the vector addition rule. O 20 N, the doghouse remains at rest
O 0N, the doghouse starts moving in one direction and then slows to a stop.
O 0N, the doghouse remains at rest.
O 70 N, the doghouse remains at rest.​

Avoltage source vs = 10 v is in series with a resistor of 10 kohm. if the source transformation theorem is applied, what will the value of the current source be in ma ?

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
