Answer:
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!

Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.
Add all the forces to find the net force on the squirrel. -2N+3N=1N
Because the positive direction is to the right, the net force of 1N is directed to the right.
When the elevator is going up (assuming the elevator is acceleration)
When the elevator is accelerating downwards, the total gravitational force would be larger.
If the elevator is accelerating upwards, then the gravitation force would be smaller, thus the tension in the string would be smaller.
Halogens have 7 valence electrons, which probably explains why they are the most active non-metals.
