Answer:
88 centimeters is the diameter of the cilinder
Step-by-step explanation:
The pressure on both ends of the lift must be the same. Assuming the piston is cilindrical, its area will be A=π*r² where r is half the diameter
Since pressure P=F/A And P1=P2
F1=2000kg.g
A1=π*r²
F2=25kg.g
A2=π*0.05²
2000/(π*r²)=25/(π*0.05²)
and we solve for A1
r²=2000*0.05²/25

r=
20*0.05/5=0.44m or 44cm
This is the radius, meaning that the diameter will be twice this number
Answer: Undefined
Step-by-step explanation:
(slope = m)

(3 divided by 0 is undefined, so the slope is undefined)
Answer:
The answer is C, zero
Step-by-step explanation:
Additive inverses are numbers that equal zero when added together.
Answer:
<u>The average speed of the frightened dot was 13 units per minute.</u>
Step-by-step explanation:
Let's find out the distance covered by the frightened dot, as follows:
Distance = (Distance from - 5 to 0) + (Distance from 0 to 34)
Distance = 5 + 34
Distance = 39
Now, let's find out the average speed of the dot, this way:
Average speed = Distance/Time
Average speed = 39/3
<u>Average speed = 13 units per minute</u>
