waves.
b:Transverse waves can be mechanical waves
or electromagnetic wave.
С:Mechanical waves can be transverse waves
or longitudinal waves.
d:Light is not a mechanical wave.
e:All the transverse waves are mechanical
waves.

It's either 3 or that ,,but if not than choose 4

C. 1s22s22p63s23p43d104s24p5

You would do 1500/4 and the answer is 375

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
