Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

Identify two types of flat panel monitors and explain their differences?

Two examples of flat panel monitors are Light-emitting diode display (LED) and Liquid-crystal display (LCD). LCD monitors light the entire backside of the LCD panel using a cold compact florescent light while LED monitors use its own light to provide the backlight. LED lights more energy efficient than the cold compact florescent light used by LCD.

What are some non examples of justice?

Where do you make use of good heat conductors?

  • Heat exchangers use heat conductors to transfer heat from one liquid to another.
  • Refrigerators/freezers use heat conductors to cool the inside of your fridge.
  • Disc brakes are made from materials that are good at heat conduction to keep them cool.
  • The processor on your computer has a heat sink on it which allows the heat from the processor to be dissipated.
  • Radiators are made of metals that are good at conducting heat
  • The element in a kettle is used to conduct heat.

What are the most common complications of stroke?

The most common complications of stroke include paralysis or weakness on one side of the body, difficulty with speech and language (aphasia), cognitive impairments, such as memory loss or difficulty with problem-solving, and emotional changes, such as depression or anxiety.

Does ice melt faster in water juice or soda?

Ice typically melts faster in water because water has a lower density than juice or soda, allowing for better heat transfer. Additionally, soda and juice often contain sugars and other solutes that can lower the freezing point of the liquid, making it slightly more difficult for the ice to melt.

Cl2 oxidation number?

Well, honey, in a compound like Cl2, each chlorine atom has an oxidation number of 0 because it's a diatomic molecule. But if you're talking about when chlorine forms a compound with something else, then its oxidation number can vary depending on the compound. So, in short, in Cl2, the oxidation number of each chlorine atom is 0. Hope that clears things up for ya, darling!

What are 3 things that are the same size as a walnut?

Three things that are approximately the same size as a walnut are a golf ball, a ping pong ball, and a large garlic clove.

It's important to note that the exact size of a walnut can vary slightly depending on the variety.

Why is friction helpful during washing the dishes?

Friction is helpful during washing dishes because it helps to physically dislodge and remove food particles and grease from the dishes. When you scrub the dishes with a sponge or brush, the friction between the surface of the dish and the cleaning tool helps to break up and lift off the dirt and grime. Without friction, it would be much harder to effectively clean the dishes and remove all the residue.

Which would have the higher temp a cup of water at 70 degrees or a bucket of water at 70 degrees?

What can you use to pour 50 mL of acid from one container to another?

That depends on the container; if the mouth of the container into which the acid is being poured is large enough, you can just pour, with no additional equipment being required. If the mouth is too small, you can use a funnel. Since you are pouring acid, you would not use a plastic funnel, but an aluminum funnel would work.
