New technology, such as renewable energy sources, has many positive aspects such as a) using nonrenewable resources. b) reducing the emissions of carbon dioxide. c) increasing the annual average temperature. d) increasing the cost of energy sources such as fuel.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

The slope of a velocity time graph over any interval of time gives the during that interval

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
