What are air masses, and how do they work?
NEED HELP ASAP!
Answer:
Need help? I'll give it to you!
Explanation:
Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.

1. Omar is sliding along the school corridor. Draw a picture of Omar sliding along the floor. Add a force arrow to show the force of friction acting on Omar.
2. Press your hands very gently and rub them. Now press much harder and rub again. Describe what you observe. What does this tell you about the force of friction?
Answer:
well all you would have to do is draw a picture of him sliding and an arrow
and as for the second one rub your hands together and tell them what you see and then explain if it was easy to do or if you had troubles because the force of friction will make your hands warm up which is why you see them rub their hands together in movies
Answer:
1. The Speed is 390
2. The Frequency is 425 Hz

How are exothermic and endothermic reactions measured in a lab?
Answer:
Exothermic and endothermic are measured by a calorimeter.
How to tell the difference between them. If change is positive, then thermal energy was released, and the process is exothermic. If the change is negative, then thermal energy was absorbed, and the process is endothermic.
それらの違いを見分ける方法。変化が正の場合、熱エネルギーが放出され、プロセスは発熱します。変化が負の場合、熱エネルギーが吸収され、プロセスは吸熱反応です。
Explain how the ocean floor affects when and how waves break. Explain how the ocean floor affects when and how waves break.
Answer:
The sea floor's slope has a significant impact on how the waves break and how rapidly the sea floor affects them as they approach the coast. The direction in which waves break can also be influenced by local tides and the approach of the ocean surge.

The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?
Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.
Explanation:
Of all the planets, which is the most different from the others? Explain.
Answer: VENUS
