Which is a statement of the principle of conservation of momentum
question 1
question 2

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

Could someone me find the answer to this problem.
