The speed is constant since there is no opposite force facing the car
That’s my best guest hope it helps !! :)
Well first of all, I think the students may have been correct.
If they didn't use distilled water, and if it wasn't exactly at
standard temperature, then the mass of 25.0 mL could
very well be 25.4 grams. We don't know that there was
any 'error' in their measurement at all.
But the question says there was, so we'll do the math:
The 'error' was (25.4 - 25.0) = +0.4 gram
As a fraction of the 'real' value, the error was
+0.4 / 25.0 = +0.016 .
To change a decimal to a percent, move the
decimal point two places that way ===> .
+ 0.016 = +1.6 % .
Their measurement was 1.6% too high.
Let's not call it an 'error'. Let's just call it a 'discrepancy'
between the measured value and the 'accepted' value. OK ?
I think it's Barium sulfate, the soild and percipitate
Mass is measured in kg
Velocity is measured in ms^-1

Answer:
this the way that hydraulic pump works:
The system of hydraulic jack lifts the heavy objects by transferring the oil from one chamber to another.
Through the suction valves into the two cylinders which creates pressure distributing the fluid equally to the points causing the objects to lift up.
hope these points helped u
any confusion then comment it
