Homework Statement
It's a simple problem, you kick a ball with an initial velocity of 5.4 m/s, the angle is 30 degrees. So the question is when does it land on the ground?
So I thought that I could find final velocity so that I can use V = V(initial) + acceleration * time. My question is, can...
I understood it now. I mistook some information given by the book. I wasn't able to see the difference on p and greek letter ro. I understand now that there is pressure or force affecting the whole glass cylinder, both from the water on the glass cylinder and the ethanol on the glass cylinder.
It says nothing about what kinds of forces that are in play. The only thing we get to know is that: the plate of glass is pushed at the end of the cylinder of glass which is then put under water.
Homework Statement
The hydraulic system is this: It has two stamps (Unsure of how I am to translate that word). Basically it is the plate on which we apply pressure. You apply pressure on one of them, the other goes up. The question is:
How high will the big stamp move upwards when the small...
Homework Statement
A thin glass plate is pressed at the end of a glass cylinder. The glass cylinder with the glass plate at the bottom is dipped in water so that the plate is 25 cm under the water surface (The glass cylinder i open, meaning only the bottom part is closed, due to the glass...
