True; scientist define work as the spending of energy. This is because energy is required to move an object. For work to be done an object has to be moved from one point to another. Work is measured in joules similar to energy which is also measured in joules. Mathematically, work done is given by the product of force and distance moved by an object or a body.

Mean: the average. you have to add the values of the numbers and then divide by the amount of numbers there are. a common mistake to avoid is forgetting to divide the numbers at the end or subtracting them instead of adding.
mean: the middle number. you would first need to order the numbers from least to greatest. a common mistake to avoid is finding the middle number before ordering it from least to greatest
these two can also be commonly mistaken for one another because of the similar spelling.
Answer:
160m/s
Explanation:
To find V Use the following formula V= F*W
V= Velocity F= Frequency W= Wavelength
V=20*8
=160m/s
