Answer:
a) Resistivity=R.A/L
Here, R=500000ohm, L=1.6m, A=2pi* (0.14/2)*0.002 m2=0.00088.........we have converted quantities into SI units
Resistivity=R.A/L
=500000*0.00088/1.6 = 440/1.6= 275 ohm.meter
b) pskin/pinterior =275/4.8=57.3
For second part, correct option is (A), because cross section area is smaller.
Answer:
V=14
Explanation:
PE=KE
mgh=1/2mv^2
2(9.8)10=1/2(2)v^2
(radical) 196= (radical)v
V=14
D. an outside or unbalanced force acts upon the object.
There’s nothing to see so there for I can’t help you
The other lights wouldn't be affected?
