The diagram below shows two forces applied to a 2.0- kilogram block on a frictionless, horizontal surface.
What is the acceleration of the block?

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 are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons

What are atoms of the same element with varying number of neutrons
