The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)
Answer:
136
Step-by-step explanation: 34 multiplied by 4
Answer: rational number
Step-by-step explanation:
The expression m over 5 would represent the number of miles the bicyclist had traveled for a time of 5 minutes. This value is a value of speed. It is the magnitude of a velocity. It represents the total distance that is traveled for given certain period of time. It is a scalar quantity since it does not have any direction. It would have dimensions of distance per time with SI units of meter per second. Other units used are kilometer per hour and miles per hour. The vector quantity counterpart of this is called the velocity where it contains the magnitude of the speed and a direction. The direction of velocity is indicated by a positive and a negative sign.
Answer:
100 degrees
Step-by-step explanation:
55+45=100
180-100=80
180-80=100
Each Triangle is a total of 180 degrees since a triangle is half a square.
Every straight line is 180 degrees
