<span>The notation of the isotopes using the atomic number and the mass number consists of the symbol of the atom, preceded by the mass number as a superscript and the atomic number as a superscript.

All the isotopes of the same element have the same atomic number. They only vary the mass number.

So, all the isotopes of oxygen have atomic number 8.

The isotope oxygen-16 has mass number 16, so it is written with the symbol O preceded by the number 16 as a superscript and the number 8 as a subscript (the two numbers to the right of the chemical symbol).

The isotope oxygen-17 has mass number 17, so it is written with the symbol O preceded by the number 17 as a superscript and the number 8 as a subscript.

The isotope oxygen-18 has mass number 18, so it is written with the symbol O preceded by the number 18 as a superscript and the number 8 as a subscript.</span>

A home remodeling company charges $10 per square yard for installing new carpets. What is the cost for installing a carpet for a
balu736 [363]

Answer:

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

Explanation:

Length of the room = l = 15.0 ft = \frac{15.0}{3} yard=5.0 yard

Width of the room = w = 12.0 ft = \frac{12.0}{3} yard=4.0 yard

(1 yard = 3 feet)

Area of the room = l × w = 4.0 yard\times 5.0 yard = 20.0 yard^2

Cost for installing a carpet for a room = $10 per square yard

Cost for installing a carpet for a room wit area 20.0 square yard :

20.0 yard^2\times $10/ yard^2=$200.0

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

If there is a 2 kg ball with the same kinetic energy which one will be moving faster
Andrew [12]

Answer:

If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word "kinetic" comes from the Greek word "kinesis" which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
