Answer:

That something is called having a high viscosity.

Explanation:

The measure expressing a "resistance to flow" is called viscosity. Viscosity relates to internal friction forces in a fluid causing it to flow with more or less difficulty. Highly viscous stuff is perceived "thick" or "sticky."

The number of energy levels filled in an atom is determined by the number of

Lelu [443]

Answer:

The number of energy levels filled in an atom is determined by the number of orbitals.

Explanation:

The highest numbers of the electrons in a given energy level relies on the presence of number of orbitals. In one orbital it contains two electrons. Electron that are present in the outer energy level of atom are known as the valence electrons. Which remains as the determining factor of the reactivity of the element. Lights are being emitted when an electron comes from higher state to the lower state.

What happens to the waves as you increase or decrease the frequency?

Vadim26 [7]

Answer:

In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease.

Explanation:

$\lambda$ = Wavelength

f = Frequency

Velocity

$v=f\lambda$

$f=\frac{v}{\lambda}$

$\lambda=\frac{v}{f}$

In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease. This is true for any wave whether sound or electromagnetic.

A force of 25 N applied to a spring stretches it by 5 cm. What is the potential energy of the spring in the compressed position?

melamori03 [73]

Answer:

Explanation:

<u>Elastic Potential Energy </u>

We find objects like springs that hold potential energy when stretched and they have the capacity to release it when left return to its equilibrium position. The elastic potential energy of a spring of constant k when is stretched a distance x is

$\displaystyle PE=\frac{kx^2}{2}$

The spring constant can be obtained if we know the force N needed to stretch the spring a distance x, by using the Hook's Law

$F=kx$

The question provides the information that a force of F = 25 N stretches a spring x= 5 cm = 0.05 m. Using the formula F=kx we can compute the value of k.

$\displaystyle k=\frac{F}{x}$
