A mirror is used to see your own reflection. Earlier in the days, people would use a still water to see their reflection. It is basically used for grooming. Spherical mirrors have been used by earlier mathematicians and physicist to conduct experiments related to geometry. </span>
Answer:
The correct option 50.0 m (<u>the units of the answers are wrong, they should be in meters and not in millimeters</u>).
Explanation:
From the first second we can find the acceleration of the object:
Where:
: is the final position = 2.00 m
: is the initial position = 0
: is the initial speed = 0 (starts from rest)
t: is the time = 1 s
The acceleration is:
Now, we can find the distance after 5 seconds:
Therefore, the correct answer is 50.0 m. All the options have the units in millimeters and not in meters hence, the units of the options are wrong.
I hope it helps you!
Answer:
The valence electrons determine an atom's reactivity.
Explanation:
The valence electrons is the electrons on the most outer layer of an atom. The higher the number of valence electrons, the bigger the reactivity of the atom. This means that when that atom is put with another substance and it reacts, it would react in a much more violent way than another atom with lower valence electrons.
Answer:
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.
Explanation:
