What experimental term is it when a ruler is dropped to the floor?

Free fall experiment

Explanation:

When a ruler or lets say any object is dropped from height on to the floor, it is called free fall. A drop object to fall on the floor to study the effects of gravity.The free fall is called movement due solely to the influence of gravity. All bodies with this type of movement have a downward acceleration whose value depends on where they are. The value of acceleration due to gravity on Earth has been found out to be 9.81 m/sec^2.

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
