The flux of 
is given by the surface integral
where 
is the given square region, which we can parameterize by
with 
and 
. The area element is
where 
is the normal vector to . Depending on the orientation of , this vector could be
or 
; either way, the integral reduces to
Answer:
Explanation:
V1 = 31 V
V2 = 168 V
charge on proton, q = e
(a)
The change in potential energy is given by
ΔU = q ( V2 - V1)
ΔU = e (v2 - V1)
(b)
ΔU = e (168 - 31)
ΔU = 137 eV
(c)
Work done = change in potential energy
W = 137 eV
W = 137 x 1.6 x 10^-19
W = 2.19 x 10^-17 J
Answer:
D.Hydrogen is a compound made of two or more kinds of atoms.
If it happens to be cruising along at 5 meters per second (about
11 miles per hour), then it covers 10 meters in 2 seconds without
any acceleration at all.
Voltage is given by the formula
V = IR (Ohms law)
where V is the Voltage
I is the current
and R is the Resistance
Here it is given that the current is I=11
Resistance is R =12
so plugging this in the formula
V = IR
V= 11 * 12
V= 132 Volts
So the Voltage for the given dryer is 132 Volts
