Homework Statement
Two capacitors, C1 and C2, are separately charged to 166 C and 348 C, respectively. They are then attached in parallel so that the + plate of one goes to the - plate of the other, and vice versa, as shown on the diagram below (notice how C2 was rotated 180 degrees before...
I do not know what I am doing wrong. Here is my work:
q/(кε) = EA, A = 2*pi*rx
E = q/(кεA) = q/(2кε*pi*rx)
V = -integral of Edr from a to b = -(q*ln(b/a))/(2кε*pi*x) = 1000 V
1000(2кε*pi)/ln(b/a) = q/x
(q/x)*10*1000 does not give me the answer. Where did I go wrong?
Homework Statement
The inner radius of a spherical insulating shell is c=14.6 cm, and the outer radius is d=15.7 cm. The shell carries a charge of q=1451 E−8 C, distributed uniformly through its volume. The goal of this problem is to determine the potential at the center of the shell (r=0)...

Liquid water, initially at 25.00 °C & 1.000 bar is heated at constant
pressure to 95.00 °C, then is compressed at constant temperature to a final
pressure at which the volume is the same as the original volume (25.00 °C,
1.000 bar). Calculate the final pressure.

I'm not too familiar with centripetal acceleration at all. But I'm assuming that the centripetal acceleration remains constant.
Does this count as 1D motion? If so, how?
Thanks for the reply.
So it's true only because centripetal acceleration does not affect tangential velocity?
Is it true for objects in 1D? Because this statement is apparently true in all cases.
The acceleration of an object can be non-zero when the speed of the object is constant.
This is true. Why? If the velocity is constant, doesn't its derivative have a slope of 0?
