Answer:
Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.
Explanation:
If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.
Answer:
Speed of light is measured in vacuum and is equal to 671 million miles per hour, 1080 million kilometers per hour, 173 astronomical meters per second.
The exact value of speed of light is considered to total 299,792,458 meters per second
Answer:
Aluminium is malleable. It means it can be hammered or changed into other shapes easily. In this case, the shape of a soft drink can.
Explanation:
This is my answer.
For calculating mean value, add up all of the values then divide by the number of them. 815/9 is about 90.6
<h3>What is mean value?</h3>
The mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations), the geometric mean, and the harmonic mean.
Moreover, the mean can be used to represent the typical value and therefore serves as a yardstick for all observations. For example, if we would like to know how many hours on average an employee spends at training in a year, we can find the mean training hours of a group of employees.
Hence, the mean can be calculated only for numeric variables, no matter if they are discrete or continuous. It's obtained by simply dividing the sum of all values in a data set by the number of values.
