How do machines transfer and convert energy

Answers

Energy transformation or energy conversion is the process of changing one form of energy to another. In physics, the term energy describes the capacity to produce certain changes within a system, without regards to limitations in transformation imposed.

What happens when you mix acid and base?

Answers

Acids are chemicals with a pH less than 7 that can donate a proton or H+ ion in a reaction. Bases have a pH greater than 7 and can accept a proton or produce an OH- ion in a reaction. If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution. This is called a neauturization and looks like 
HA + BOH → BA + H2O + heat

A chemical reaction by definition forms new chemicals (called the products) from the initial chemicals (called the reactants). It should make sense that the identity of the products formed depends on what reactants we start with. Adding an acid to a base is an example of a chemical reaction, so we should expect to see new products. Although there is a pattern to this type of reaction, ultimately the products formed depend on what acid and what base are used.

Sediments are almost always deposited in flat layers. Does it appear that forces in the Earth affected the rock layers in this region? What clues do you have?

Answers

Answer:

Explanation: Sediments or sedimentary rocks are formed from pre-existing rocks broken through the agents of denudation such as air, ice, water flow which carries the particles and deposits it, the accumulation of one layer on the others is called DEPOSITION. As the deposits keeps building, LITHIFICATION occurs which involves overburden pressure acting on the sediments in layers.

Note that during deposition oldest layers are below, while the younger layers are above

A condor has a wing span of 3.05 m. What is the wing span in feet

Answers

Answer:

The condor has a wing span of 10 feet

Explanation:

This can be solved by a simple rule of three

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

In this problem, our measures are the wing span of the condon in meters and the wing span of the condor is feet. As the value of one of these measures increases, the other is going to increase too.

We know that 1m has 3.281 feet,

So we have the following rule of three:

1m - 3.281 feet

3.05m - x feet

x = 3.821*3.05

x = 10 feet
