<span>Use Charles' Law:
v1/T1 = v2/T2
88.2/(273+35) = v2/(273+155)
where v2 is the new volume.
I hope this helps!!!</span>
Answer:
D. The water on her skin evaporates quickly and cools her skin.
Explanation:
Answer:
they are both played by hoomans
Answer:
hmm let's see
Explanation:
ok, ill use the second equation of motion, u see its quite simple
recall that
average velocity= u+v/2
now think of that v like a box you can can call it velocity lol obviously its velocity
now remember the first equation of motion which is
v=u+at now this is inside the box, now you have to replace the v with it
then it becomes u+u+at/2
now u notice there are two initial velocity u know what to do with that
now it becomes
2u + at/2 now since the numerator applies to both then you can simplify it like this
2u/2+at/2
all the same the pont im trying to make is that you can use imaginative ways to mater derivation you can also reverse it if you don't unferstand you can drop your number
Answer: a) C decreases; b) Q stays the same; c) E is the same
d) ΔV increase
Explanation: In order to explain this problem we have to consider the following:
C=εoA/d where A and d are the area and the separation of the plates, respectively.
Increasing d, produces a decrease of C.
Q remain constant becasuse the plates are charges and the wire are isoloted each other.
We also know that ΔV=E*d where E is electric field between the plates.
And E= Q/εo*A ( a constant between the plates)
As we can see from above, ΔV depends directely of the d so if d increase ΔV also increase. To do that we have to do work on the system.
