Options
a. The worker carried the lunch up to the 53rd floor in the elevator.
b. The worker got a ride in a helicopter to the top of the 68-floor building and then carried the lunch down in the elevator to the 53rd floor?
c. The Worker carried it up the stairs to the 53rd floor.
d. Gravitational potential energy does not depend on the path taken.
Answer:
The gravitational Energy would remain the same in all cases.
Explanation:
Gravitational Energy is a conservative energy and its potential energy comes from gravitational actions.
An instance is when someone lifts a weight from the floor to a certain height and then dropped the weight back to the floor; the work done by the field will not be altered at all; it'll be the same throughout.
If otherwise, it'll be against thermodynamics 2nd law of physics because the object would have remaining energy after returning to the starting point,
For this reason, the gravitational potential energy only depends from the height, and is independent from the path taken to reach there.
Answer:
Kinetic energy can be solved by using the following formula: Kinetic energy = (1/2)*m*v^2
Explanation:
Answer:
The answer is 1.63 x 10 -7 N
Explanation:
Using sound waves, sonar signals allow oceanographers to determine ocean depth.
Answer:
An independent variable is the variable in an experiment that is changed. A dependent variable is the resulting variable that "depends" on the changes made to the independent variable. Controlled variables are all of the other variables that are kept the same between all changes made to the experiment. You would graph the independent variable and dependent variable. The independent variable will be found on the x-axis while the dependent variable can be found on the y-axis.
