If there is no net force on an object, then the object will a) continue to accelerate
B) begin moving slow down
c) maintain it's rate of speed
d) have to be at rest

Answers

If there is no net force on an object, then the object will maintain it's rate of speed. Basically, net force is the change in an object's motion. If it is stationary and not moving, the object will stay stationary. If the object is moving at a rate of 2 miles per hour, it will constantly continue to move 2 mph because there is no net force.

Predict the changes in the number of particles based the diagram.A) Pressure is indirectly related to moles.
B) Volume is proportionally related to moles.
C) Moles remains constant as pressure changes.
D) Temperature is directly related to the moles.

Answers

Pressure is indirectly related to volume.

As the volume increases at a constant temperature, the pressure decreases.

The changes in the number of particles based on the diagram is that Volume is proportionally related to moles. The answer is letter B. The rest of the choices do not answer the question above.
