Alog splitter uses a pump with hydraulic oil to push a piston, attached to which is a chisel. the pump can generate a pressure of 2.3x107 pa in the hydraulic oil, and the piston has a radius of 0.041 m. in a stroke lasting 29 s, the piston moves 0.57 m. what is the power needed to operate the log splitter's pump?

we are given

The pump can generate a pressure of 2.3x107 pa

so,

a radius of 0.041 m

so,

a stroke lasting 29 s, the piston moves 0.57 m

so,

Firstly, we will find area

now, we can use power formula

F=pA

W=Fh

so, W=pAh

we can plug it

now, we can plug values

now, we can simplify it

Power=2386.92414 watt.........Answer

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
