A balance was tested against a standard calibration mass with a certified value of 200.002 g and produced the following readings

in grams: 195.587, 195.586, 195.588, 195.587, 195.589. The performance of this balance is best described as:

Answer:

Precise but not accurate.

Explanation:

We can tell the performance of the balance is precise, because the repeated measurements give values close to one another.

However, the performance of the balance is not accurate, as the mean value of the repeated measurements (195.587) is not close to the value considered as true (in this case the standard calibration mass with a certified value of 200.002 g).

Report the number 315.05 to 3 significant figures.
emmainna [20.7K]

Answer:

315.

Explanation:

Hello.

In this case, since the given number has five significant figures as the zero is to the right of the first nonzero digit (3), if it is required to report it with three significant figures, it is necessary to "cut" it at the first five without any rounding since the subsequent zero is less than five.

Thus the number turns out:

315

Best regards.

Which statement best describes what happens when thermal energy of the
vitfil [10]

When the thermal energy of the air around a fire is transferred to the surrounding air  A. The thermal energy is spread out by the surrounding air.

Thermal energy transfers occur in 3 approaches conduction, convection, and radiation. whilst thermal power is transferred among neighboring molecules that are in touch with each other, which is referred to as conduction.

Thermal strength refers to the power contained inside a system that is liable for its temperature. heat is the go with the flow of thermal electricity. an entire department of physics, thermodynamics, offers how heat is transferred among exceptional systems and how work is accomplished in the manner.

Thermal strength also referred to as heat strength is produced when a rise in temperature reasons atoms and molecules to transport quicker and collide with each other. The energy that comes from the temperature of the heated substance is referred to as thermal strength.

Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.
