Benjamin Franklin, George Washington, and the brothers
Answer:
10 Joule
Explanation:
The solution and answer are well written in the Pic above.
To solve this problem we will apply the concepts related to the kinematic equations of motion. We will start calculating the maximum height with the given speed, and once the total height of fall is obtained, we will proceed to calculate with the same formula and the new height, the speed of fall.
The expression to find the change in velocity and the height is,
Replacing,
Thus the total height reached by the ball is
H = 22m+13.0612m
H = 35.0612m
Now calculate the velocity while dropping down from the maximum height as follows
Substituting the new height,
A geyser is actually a devise that coverts electrical energy
into heat energy for heating up water. The heating element that is inside the
geyser actually gets heated up and then in turn it heats the water in contact
with it within the geyser. There is also a thermostat device within the geyser
that cuts off the heating when the water temperature reaches the desired level.
This helps in stopping of electrical energy loss. One inlet brings in cold
water while another outlet gets rid of the hot water. When the temperature of
the water falls below the desired level the heating is again started by the
thermostat.
