Answer: A convex lens is used to converge ligtht.

Explanation:

A concave lens is a lens that is thicker on the ends than in the middle. As consequence of this, a concave lens diverges (separate) the rays of light. A concave lens is also called diverging lens.

A convex lens is is thicker in the middle than on the ends. As consequence of this, a convex lense converge the parallel rays that pass through it. A convex lens is also called converging lens.

The answer would be :
A convex lens is used to converge ligtht.

A convex lens is is thicker in the middle than on the ends. As consequence of this it wl reflect light but as the object go near to the mirror, it would be inverted and virtual. So you eill expect an inverted image of you.

Question 4

nata0808 [166]

Answer:

A. She can run the same distance in a shorter amount of time.

Explanation:

Speed can be computed with the formula:

$v = \dfrac{d}{t}$

Where:

v = speed

d = distance

t = time

So if you look at the formula, distance there tells you how far an object has traveled, and the time tells us how long it took to cover that distance. As you can see, speed and time are inversely proportional. This means that as one goes up, the other goes down. So if we reduce time travelling a certain distance, the speed increases.

Explain what happens in the reaction between sodium hydroxide and hydrochloric acid.Explain how protons are donated and accepted

Artyom0805 [142]

Answer:

Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release of heat. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water – compounds that are ultimately harmless, even beneficial, to human beings.

2) An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids. A reaction between an acid and base is called a neutralization reaction.
