What happens to light when it enters a lens? A. It speeds up.

B. It is reflected.

C. It is refracted.

D. It becomes brighter.

Answers

Good Morning! When the light passes through a lens - whether of increase or withdrawal - it tends to be refracted, that is, to suffer a deviation in its trajectory. Depending on the type of lens, it may be that some of the light is reflected too, but this is not the common parameter. Correct letter is therefore c). Hugs!Hope this helps.

Y = -2x + 5 and 2x + y = -7​

Answers

Answer:

not true

Ions are atoms of the same element that have a different number of _____________.Question 13 options:

A. nuclei


B. nucleons


C. electrons


D. protons


E. neutrons

Answers

The correct option is C.

How do an atom and an ion of the same element differ?

Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

What makes different ions of the same element different?

An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
