Answer:
We would not be able to make our way around the earth's surface, to read, to sculpt or to create technology because we cannot see!
Explanation:
The minimum angular separation that can be distinguished by an eye gives the angular resolution of the eye.
Given that the Angular resolution with infrared radiation is =
equal to 
This resolution is very much greater than that of the eye 
The angular resolution that our eyes can see is about
at arms length
Angular resolution of infrared =
at arms length
We therefore cannot read, sculpt or create technology because we cannot see.
To solve this problem we will use the concepts related to the resulting Vector Force product of two components, that is,

If we take the Force of 50 N as the force in the X direction and the Force of 40 N in the Y direction we will have to:



Finally, since Newton's second law, acceleration can be determined as




Therefore the resultant magnitude of the acceleration of the object is 
Answer:
A is the answer
Explanation:
That's why it ranges from big to small.
