A distance-time graph indicates that an object travels 2 m in 2 s and then travels another 80 m during the next 40 s. What is th

e average speed of the object?

GaryK [48]4 years ago

To find the average speed, we must calculate the total distance covered by the object and then divide it by the total time of the motion.

The total distance covered by the object is
S=2m+80m=82 m
while the total time of the motion is
t=2s+40 s=42 s

Therefore, the average speed of the object is
v= \frac{S}{t}= \frac{82 m}{42 s}=1.95 m/s

Which of these items are made of cells? Check all that apply.
Katen [24]

Answer:

The correct answers are: Bacteria, Horses, Humans and Mushrooms.

Explanation:

All living organisms are made up of cells. A cell is a microscopic atomic unit and is made up of cytoplasm, one or more nuclei, and a membrane.

They are divided into eukaryotic cells (with nucleus) and prokaryotic cells (they do not have a nucleus).

Depending on the number of cells that living organisms have, they can be classified as single-celled organisms, which are made up of one cell. For example bacteria.

Or they can be multicellular organisms, formed by two or more cells, for example horses.

PLEASE HELP :)

1) in the opposite direction always
2) drag force is the force that acts in the opposite direction of the applied force (air resistance if a drag force for example)
3) frictions forces between the sole and the ground as the owner walks
4) chalk would glide very easily, so a creaking sound could never be produced, but also one could not write anything on the board!
5) I apologize for my lack of familiarity with the kind of sport but the probable answer is to raise the friction of their hands in order to decrease slipping and get a tighter, more firm grip
