Sure. If some of the items on the list are positive and some are
negative, then their average can be positive, negative, or zero.
But if all of them are positive, then their average must be more
than zero. Remember that the average is always greater than the
least item on the list, and less than the greatest one.
size zero in the UK is an average of size 4
Yes it can be.
You don't need to. Average deviation (about the mean) is always zero!
Because the average deviation will always be zero.
On average, approximately zero.
in circular motion
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
why average product labour never gets to zero
You will include zero in finding an average if it is present in the problem. For example, you want to average quiz scores of 75, 100, 90, 0, 80. You would include zero. If zero isn't listed, don't use it.
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Yes, it is possible to have zero displacement and a non-zero average velocity. This can occur if an object moves back and forth over a certain distance so that the total displacement is zero, but the average velocity is non-zero due to the object covering distance in both directions.
No, it can't. Average VELOCITY can be zero, though.
The shed is of zero mass and zero weight
An example of average velocity of zero is when an object moves in a full circle and returns to its starting point within a given time interval. Since the displacement is zero (starting and ending at the same point), the average velocity is also zero.
Empty cells are ignored completely when calculating an average in Excel. If a cell contains a zero, then it is included in the calculation of the average because zero is a number and it is relevant to include it. If you want to exclude zero values in the calculation, then you could use the AVERAGEIF and set it to only include values that are above zero.
The average velocity becomes zero when an object returns to its initial position after moving in a straight line. This happens when the displacement is zero over a period of time.
The average is zero.
