Answer:
the maximum speed of the ball is 12.65 m/s
Explanation:
Given;
mass of the ball, m = 40 g = 0.04 kg
spring constant, k = 25 N/m
Apply the principle of conservation of energy;
The Elastic potential energy of the spring will be converted into Kinetic of the ball;

Therefore, the maximum speed of the ball is 12.65 m/s
Answer:
The 'pleasure centers' are located in the brain structure known as the: amygdala. See the explanation below, please.
Explanation:
The amygdala is part of the limbic system and deals with the control of emotions and feelings, through responses of satisfaction or fear. It has a close bond with the frontal lobe which can inhibit some behaviors.
Kinetic energy equation is KE= 1/2mv^2. So plug in the numbers and you get a Kinetic Energy of 203.904 J
Adjust the height of the wooden rod so that it just touches the surface of the water. Switch on the lamp and motor and adjust the speed of the motor until low frequency waves can be clearly observed... Count the number of waves passing a point in ten seconds then Divide by ten to record frequency.
