What can happen to solar radiation when it enters atmosphere

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.

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?
