It's true answer that interference is the evidence of the particle nature of light..
Answer: Fluorinated gases (F-gases) are man-made gases that can stay in the atmosphere for centuries and contribute to a global greenhouse effect. this is extremely bad for the earth and is causing downpour on our plants and animals. Why would we creat gases we can not get rid of its ver diapointing
When air is warmer, the air particles move faster due to the heat, causing kinetic energy of the particles to increase. And as sound is produced when energy is transfered from one particle to another, with the particles moving faster, the energy will also be transfered faster, thus, allowing sound waves to travel faster in warmer air than in colder air
I think it’s c but check cause I’m not sure
Answer: 34.6N
Explanation:
1) The friction force that acts on the skis as you move down the mountain follows the rule:
Friction force = friction kinetic coefficient × Normal force
2) The friction kinetic coeffcient for waxed wood skis on snow is reported in some literature as 0.10.
3) The normal force is given in the statement: 346 N
4) With that you calculate the friction force as:
Friction force = 0.1 × 346N = 34.6N
