Answer with Explanation:
We are given that


We have to find the direction and magnitude of the third force acting on the object.
Resultant force,F=

The object moves with constant velocity .Therefore, net force on object is equal to zero
So,Third force,
Direction,

Angle lies in second quadrant because the direction of third force is opposite to the direction of the resultant force of F1 and F2.
Therefore,
Answer: No.
Explanation:
A scientific theory is an explanation of some aspect of the natural world that can be tested several times, and follows the scientific method. And, when possible, theories are tested with experiments.
Now, a scientific theory must meet some criteria, and one of those is that it must be supported by several (and independent) strands of evidence.
In this case, we have only one, Meatball, and it is not enough, then it can not be a scientific theory.
If it is a headwind it means it's travelling against the motion of the plane. This means it's velocity is simply v=720-16=704 km/h due east.
Answer:
Option c. Inter-rater Reliability
Explanation:
Here, the rating is done by a group of data collectors under training for evaluation children's pain on Faces scale which is a scale ranging from 0 to 10 with different expressions or faces with a happy face at 0 to a crying face at 10.
Also in Inter-rater Reliability, the relative consistency of a study or test is assessed and the extent to which different group members rated the same behavior, the consistency of which is evaluated.
Thus it can also be helpful in interviews, etc.
