I would say the plastic grip because glass, wood, and plastic are all good conductors of electricity
Answer:
5.10 m/s
Explanation:
The volumetric flow rate for an incompressible fluid through a pipe is constant, so we can write:
(1)
where
is the cross-sectional area of the first part of the pipe
is the cross-sectional area of the second part of the pipe
is the speed of the fluid in the first part of the pipe
is the speed of the fluid in the second part of the pipe
Here we have:
is the radius in the first part of the pipe, so the area is
is the radius in the first part of the pipe, so the area is
Using eq.(1), we find the fluid speed at the second location:
Answer:
Option D, is closest to the answer = 950.
The temperature of the resistor varies based on the variation in the temperature. The equation that describes the relation between the two of them is:
<span>R = R0[1+ alpha(T-T0)] where:
</span>R is the new resistance we are looking for
alpha is the temperature coefficient of resistance. For nichrome, alpha = <span>4x10^-4/C
T0 is the standard temperature =11.5
R0 is the resistance at T0 = 200 ohms
T is the temperature at which we want to get R = 0
Substitute in the equation to get R as follows:
R = 200 [1+4*10^-4 (0-11.5)] = 199.08 ohm</span>
