Orchids are a family of thousands of types of flowers that all share the same shape. Many gardening clubs are devoted to collect
ing, studying, and growing orchids, because it is difficult to grow them outside of their natural habitats.
Which are scientific questions that can be asked about a collection of different orchid types? Check all that apply.
Which type needs the highest temperatures to grow in?
Which type has the most beautiful colors?
Do all of the types make food the same way?
Do all of the types deserve the same amount of admiration?
How can someone decide which type makes the best gift?
How long does it take for a specific type to make its seeds?

1) Average speed
2) Displacement
Explanation:
1)
Speed is a scalar quantity which gives a measure of how fast a body is moving. It is equal to the ratio between the distance travelled by an object and the time taken to cover that distance:
where
d is the distance covered
is the time taken
It is important to note that being a scalar, speed does not have any direction. Moreover, distance is also a scalar quantity, which corresponds to the total length of the path covered by the object, regardless on the direction taken.
So, the equation "travelled distance/elapsed time" corresponds to the average speed. (where the term average refers to the fact we are not measuring the speed at a specific instant in time, but on a certain time interval .
2)
Velocity is a vector quantity, so it has both a magnitude and a direction.
The magnitude of the velocity is given by:
where
is the change in position (or displacement) of the object
is the time taken
And the direction of the velocity corresponds to the direction of the displacement.
We must note that while distance does not depend on the direction, displacement does. In fact, displacement measures the difference between the initial and final position of the object.
Therefore, the equation "change in position / elapsed time" is equal to the average velocity.
