A small toy car travels 2.0 meters in 120 seconds. what is the speed of the car?
mamaluj [8]

Answer:\dfrac{1}{60} ms^{-1}

Explanation:

Speed of an object is defined as the ratio of the distance covered by the object to the time taken to cover that distance.

Let s be the speed of the object.

Let D be the distance travelled by the object.

Let t be the time taken by the object.

So,s=\frac{D}{t}

s=\frac{2}{120}=\frac{1}{60}ms^{-1}

So,the speed of the car is \frac{1}{60}ms^{-1}

Give examples of the one element from the alkaline earth metal group and one from the noble gases group. Include each element at
zhuklara [117]
Alkali metals: left column of your periodic table (not hydrogen, but anything below it). They have one valence electron, which they are happy to share in a reaction.

Halogens: second column from the right of your periodic table. They are one electron short of a full shell, so they are reactive in the opposite way that alkalis are--they want electrons.

Atomic number (number of protons) is the big number on the periodic table square. Hydrogen's is 1.

Atomic mass is a little number down below. For example, Hydrogen's is 1.008.

Neutrons are a tricky subject, because different isotopes of the same element can have different numbers of neutrons. You can't generally get this from the atomic mass, because the atomic mass is a weighted average of naturally occurring isotopes. Hydrogen can have 0,1, or 2 neutrons. To answer this, you'd have to choose a particular isotope from the table of isotopes (a completely different chart from the periodic table) which has a certain number of neutrons: n = weight - Z.

Valence electrons are the electrons in the outermost shell. (The column of the table).
