How do electrons and protons differ in their electric charge?

imagine that you are on a spaceship that is far from the sun or any planet. Explain why a 500 kg piece of equipment would be difficult to move, even though the object would be weightless?

What is a loose icy body with a long narrow orbit?

Humans have three types of cone cells in their eyes, which are responsible for color vision. Each type absorbs a certain part of the visible spectrum. Suppose a particular cone cell absorbs light with a wavelength of 430nm.

It has been proposed that a spaceship might be propelled in the solar system by radiation pressure, using a large sail made of foil.

All atoms have moving electric charges. why then, aren't all materials magnetic?

Given the reaction at equilibrium 2NO2 (g) = N2O4 (g) + 55.3kj if the pressure on the system is increased anda the tenperature is held constant:equilibrium will:

All of the fallowing are possible sources of error in a scientific investigation exept for a. measuring the materials of an experiment incorrectly. b. not controlling all the variables in an experiment c.

While exploring a castle, Exena the Exterminator is spotted by a dragon who chases her down a hallway. Exena runs into a room and attempts to swing the heavy door shut before the dragon gets her.

The stabilizing effect of alkyl substituents on carbocations can be explained through

A torsion pendulum is made from a disk of mass m = 7.1 kg and radius r = 0.71 m. a force of f = 42.4 n exerted on the edge of the disk rotates the disk 1/4 of a revolution from equilibrium.
