Answer:

The energy of the electron in a helium ion is -5.44\times10^{-19}\ J

Explanation:

Given that,

Charge = +1

Value of n = 4

Suppose k=2.179\times10^{-18}\ J

We need to calculate the energy of the electron in a helium ion

Using formula of energy

E_{n}=-k\dfrac{z^2}{n^2}

Put the value into the formula

E_{n}=-2.179\times10^{-18}\times\dfrac{2^2}{4^2}

E_{n}=-5.44\times10^{-19}\ J

Hence, The energy of the electron in a helium ion is -5.44\times10^{-19}\ J

If KE becomes less than IF, what phase change occurs?
netineya [11]

Answer: liquid to solid

Explanation: Kinetic energy is the energy possessed by an object by virtue of its motion.

Solid is the phase of matter where particles have strongest inter molecular forces and thus molecules posses no kinetic energy.

Liquid is the phase of matter where kinetic energy of the molecules is almost equal to the inter molecular forces.

Gas is the phase of matter where kinetic energy of the molecules is more than the inter molecular forces present among molecules and hence the molecules move randomly.

Thus the phase change is from liquid to solid.

With light microscopy, if the objective lens (lens closest to the specimen) magnifies 40-fold, and the eyepiece lens magnifies 1
Fed [463]

The final magnification will be 400-fold or 400 times the original size of the object.

For magnifying smaller objects, a compound microscope is used.

A compound microscope consists of an objective and an eyepiece, whose diagram is shown in the adjoining image.

The lens  near  the object is called an objective and the other one is the eyepiece.

Let the magnification of the objective be m1

Let the magnification of the eyepiece be m2

The final magnification by the microscope, M, will be

M = m1 x m2

Putting the values in the above equation

M = 40 x 10

M= 400

Thus, the final magnification will be 400-fold or 400 times the original size of the object.

Please match the words to the definitions!!

Explanation:

1. The Centauri star system consists of 3 stars and is about 4.37 light-years away from Earth. (A light-year is the distance that light travels in a year.)

2. We see the visible spectrum which consists of colors red, orange, yellow, green, blue, indigo, and violet. (The visible spectrum is the range of light that our eyes can detect.)

3. Because air has a lower index of refraction than water, the light beams making up the image of the fish I see bends as it leaves the water and enters the air. (Index of refraction determines how light bends when moving from one medium into another.)

4. When I look at my reflection in the mirror, the light reflects off the mirror at an equal but opposite angle as it hits the mirror.

5. When looking into a concave mirror the center is further away from you than the outside edges.  (Concave mirrors cave in.)

6. Forklift drivers are careful to look in the convex mirrors placed at blind intersections in the warehouse.

7. is transparent and the light goes through without distortion.

8. The electromagnetic spectrum refers to any or all of the possible wavelengths of "light", both the visible light and invisible light.

9. The transmission of light through a medium means it goes through it.

10. The absorption of light by a medium means it is absorbed by it.
