Applied force Newtons
Frictional Force Newtons
Normal Force Newtons
Tension Force
Net Force Newtons
The weight of the girl is 300 N. The applied force, frictional force, and normal force are all zero. The tension force in the bar is 300 N, and the net force is zero.
The weight of the girl can be calculated using the formula:
Weight = mass × gravity
where mass = 30 kg and gravity = 10 m/s2. Therefore, Weight = 30 kg × 10 m/s2 = 300 N.
Since the girl is motionless, the net force acting on her is zero. In this case, the tension force in the bar equals the weight of the girl, which is 300 N. The other forces (applied force, frictional force, and normal force) are also zero since the girl is not moving.
Therefore, the forces are:

Explanation:
Behaviorists are unlikely to perceive cognition as part of learning because they believed that learners respond to stimulus. It is the negative and the positive reinforcement that the learners receive that shape their behaviors or responses to certain stimuli and not cognition.
