PLEASE HELP I'LL MARK BRAINLIEST Earth is often called "the water planet" because most of its surface is covered by oceans. Describe the effect on Earth's oceans if a) Earth traveled around the sun between Mercury and Venus and b) if it traveled around the sun between Jupiter and Saturn.

What are two different ways you could find the value of a? explain these methods.

An element becomes a positively charged ion when itloses protons.loses electrons.gains electrons.gains neutrons.

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
