Answer:
I think it is the last one.
Explanation:
I am not sure because i am stuck on this one, too.
now you justhave to solve the last numbers because...Iam sooo Lazy right now
The temperature rises until the water reaches the next change of state — boiling. As the particles move faster and faster, they begin to break the attractive forces between each otherand move freely as steam — a gas. The process by which a substance moves from the liquid state to the gaseousstate is called boiling.
Here mass is floating on the piston at equilibrium
So it will have constant pressure always remains constant
So final pressure is same as initial pressure = 900 kPa
now we can say
so final pressure is 900 kPa and final volume is 1.14 m^3
Answer:Wrap more turns of wire around the nail.
Explanation:The power of an electromagnet is directly proportional to the amount of electricity passing through that electromagnet.
Now,if they increase the number of rounds of the copper coil,the electricity conducting surface amount will also increase.
And that's why the electricity passing through that electromagnet will increase along with the electromagnetic power of that electromagnet.
• Increasing the battery voltage :
If they increase the battery voltage,the electricity which is passing through that electromagnet will also increase in amount .
And as discussed previously,the increasing amount of electricity will also increase the electromagnetic abilities of the electromagnet.
