How much work is done when you push a crate horizontally with 130 N across a 5.0-m

On cool spring mornings, veils of fog can often be seen rising above warm lakes and ponds. this type fog is an example of ______

brilliants [131]

<h2>Answer: evaporation</h2>

Explanation:

Evaporation fog occurs when surface air is much colder and relatively less saturated than water. Then, when the water evaporates, it inmediately condenses again in small drops of water that stay suspended very close to this body of water.

In other words: This type of fog occurs when cold air moves over warmer water. And it is this difference in temperature that contributes to the formation of fog over the lakes, especially near the polar regions.

Which of these stars has the coolest surface temperature?A. A starB. F starC. G starD. K star

morpeh [17]

Answer:

D. K star

Explanation:

Stars are classified into different groups according to their peak wavelength and their surface temperature.

In particular, we have the following group of stars, which correspond to the following surface temperatures:

Group O - Temperature > 25,000 K

Group B - Temperature 11,000 - 25,000 K

Group A - Temperature 7,500 - 11,000 K

Group F - Temperature 6,000 - 7,500 K

Group G - Temperature 5,000 - 6,000 K

Group K - Temperature 3,500 - 5,000 K

Group M - Temperature < 3,500 K

So among the options given, the star with the coolest surface temperature is star in group K.

Cathode rays are negatively charged

Explanation:

Thomson's cathode ray beam bent towards the positively charged plate. With this information, he was able to conclude that the rays were negatively charged.

Cathode rays were discovered by J.J. Thomson based on his experiment on the gas discharge tube. He was able to discover some of the properties of the wave.

One notable one was that he observed that the rays deflected towards the positively charged plate.

Since unlike poles attract then he concluded that the cathode rays were negatively charged.
