As the ball is moving in air as well as we have to neglect the friction force on it
So we can say that ball is having only one force on it that is gravitational force
So the force on the ball must have to be represented by gravitational force and that must be vertically downwards
So the correct FBD will contain only one force and that force must be vertically downwards
So here correct answer must be
<em>Diagram A shows a box with a downward arrow. </em>
Answer:
Migration
Explanation:
Migration is the movement of organisms from one region or place of habitat to another region. Organisms migrate from one region to another to increase their rates of survival. Migration of organisms from one habitat to another may be due to unavailability of insufficiency of resources that are required for their survival.
Answer:
V = 1.41 m /s
Explanation:
Movement in both wood board and boy is created by internal forces . No horizontal external force acts on them . So conservation of momentum will apply on both of them for movement in horizontal direction.
Mass of wood board x velocity = mass of boy x velocity
58.1 x V = 48.3 x 1.69
V = 1.41 m /s
I mean i guess its the metric system?
