29. A boy lifts a book with the weight of 30.0 N from the floor to the top of a table, a vertical distance of 2.0. meters. Compute the increase in the potential energy of the weight. Remember to include your data, equation, and work when solving this problem.

60J

Explanation:

Since the book's weight is 30N and weight = mass * gravity (around 10m/s²):

30 = X * 10 ===>   X = 3.

Using the potential energy formula we have Gravity * Height * Mass:

10 * 2 * 3 = 60J

i don't know, you need to give me some answers.

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
