Explanation:
From the options provided the best description of scissor is that scissors helps to scrap things down. This is the main purpose of scissors, to cut things, and by doing so you are breaking up a larger object into smaller and more manageable scraps.

Although a pair of scissors has two holes it is not necessarily the best description of it.
Answer:
In Milgram's experiment, compliance, or doing what the experimenter asked,
the teacher and the learner were in the same room. -C.
Answer:
Part a)
Part b)
Part c)
Explanation:
As we know that acceleration is rate of change in velocity of the object
So here we know that
Part a)
differentiate x and y two times with respect to time to find the acceleration
Now the acceleration of the object is given as
at t= 1.1 s we have
now the net force of the object is given as
now magnitude of the force will be
Part b)
Direction of the force is given as
Part c)
For velocity of the particle we have
now at t = 1.1 s
now the direction of the velocity is given as
