Which energy depends the arbitrarily assigned zero level
Answers
Potential energy does.
A book on the floor has negative potential energy relative to the seat
of your chair, zero potential energy relative to the floor, and a whole
bunch of positive potential energy relative to the ground if the floor
is the floor of the passenger jet in which you are cruising and dropped
your book on the floor.

Answer:
c. 0.71 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 0 (because when the ball reaches the top, there is no movement)
Vo = initial velocity = 7 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time [s]
Note: The negative sign of the equation means that the movement is againts the direction of the gravity acceleration.

I'm pretty sure that the "block" of which you speak is one in a pattern
of them that covers the drawing you have of the rectangle, and now
I need to explain something to you:
The REASON for printing that drawing next to the question that you
partially copied is that the drawing has information that's needed to
answer the question with, and rather than repeat all that information
in the question, it just says "LOOK AT THE DRAWING !"
In fact, the whole point of the question may not be just to remind you of
what "perimeter" means. It's more likely that the purpose of this problem
is to make you pick the information you need off of a drawing.
Either way, if you'll kind of "read between the lines" of the part of the
question that you DID copy, it should be pretty obvious to you that nobody's
going nowhere in the direction of a solution without SEEing the drawing.
So my bottom-line conclusion regarding a solution for this problem is:
Not possible with the given information.

A tuna fish is streamlined to reduce friction which describes the type of of friction the fish must overcome drag force. Drag force affects the fall of a tuna fish because the area of a body has an increase in surface area and hinders the flow of the molecules around it thus increasing the drag force.

Explanation:
1. Location.
Hurricanes are defined as severe tropical storms that form over warm ocean waters starting as storms in the Caribbean(North American continent) or off the west coast of Africa. As the storms drift slowly westward, they gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power.
Warm, moist air moves toward the center of the storm and spirals upward. Hurricanes rotate in a counter-clockwise direction around an “eye.”
2.
It is low lying. Majority of their lands are just a few feet above sea level.
3. Most of the infrastructures are built on rocks that are permeable to water. Hence, water bubble or seep out in unexpected places. Building of sea walls and other barriers to prevent rising seas, storms etc.

Answer;
B. the number of protons and neutrons
Explanation;
- Nuclear reactions involve a change in the nucleus of an atom, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
- Therefore the parts of an atom that can change during a nuclear reaction but can not change during a chemical reaction is the number of protons and neutrons that are found in the nucleus.

Answers
Answer:
b. only within the moon’s umbra.
Explanation:
Solar eclipse occurs when Moon comes between the Sun and the Earth in straight line and blocks the sunlight. A shadow of moon castes on the surface of the Earth. The region passing through the moon's umbra would view a total solar eclipse. The moon completely hides the surface of the sun. It would be visible to the people residing in the bright side of the Earth within the Umbra of the moon.
