Answer: Addition of
salt bridge
To generate a standard
electromotive force, an addition of salt bridge is essential to help maintain
electrical neutrality within the internal circuit and prevent the cell from
rapidly running its reaction to equilibrium.
In addition, salt bridge contains potassium
sulfate, an inert electrolyte where its ions will diffuse into the separate half-cells
to stabilize the building charges at the electrodes and produce electricity.
According to the internet over 2% of earths fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil.
This question is incomplete, the complete question is;
A particle is directed along the axis of the instrument in the figure below. A parallel plate capacitor sets up an electric field E, which is oriented perpendicular to a uniform magnetic field B. If the plates are separated by d = 2.0 mm and the value of the magnetic field is B = 0.60T.
Calculate the potential difference, between the capacitor plates, required to allow a particle with speed v = 5.0 × 10⁵ m/s to pass straight through without deflection.
<em>Hint </em>: ΔV = Ed <em>
</em>
Answer:
the required potential difference, between the capacitor plates is 600 V
Explanation:
Given the data in the question;
B = 0.60 T
d = 2.0 mm = 0.002 m
v = 5.0 × 10⁵ m/s.
since particle pass straight through without deflection.
F = 0
so, F = F
qE = qvB
divide both sides by q
E = vB
we substitute
E = (5.0 × 10⁵) × 0.6
E = 300000 N/C
given that; potential difference ΔV = Ed
we substitute
ΔV = 300000 × 0.002
ΔV = 600 V
Therefore, the required potential difference, between the capacitor plates is 600 V
<u>Electromagnetic powers versus Molecules: </u>
Electrons are kept in the circle around the core by the electromagnetic power, in light of the fact that the core in the focal point of the particle is decidedly charged and pulls in the contrarily charged electrons.

<u>Solid Nuclear power versus Molecules: </u>
The solid atomic power holds most standard issue together on the grounds that it limits quarks into hadron particles, for example, the proton and neutron.
<u>Feeble power versus Molecules: </u>
In atomic material science and molecule physical science, the frail cooperation, which is additionally frequently called the powerless power or feeble atomic power, is the instrument of communication between subatomic particles that is liable for the radioactive rot of iotas.

<u>Gravity Vs. Particles: </u>
Gravity influences molecules a similar way it influences all other issue. Each iota makes its own gravitational field which draws in all other issue known to man.
Answer:
Solution of each part is given below .
Explanation:
Given :
Wavelength of laser in air is , .
We know its velocity in air is , .
So , its frequency is ,
We know , frequency is source dependent only and since the source is same so frequency will be same and equal to .
Therefore , its velocity in Lucite is :
New wavelength is :
Hence , this is the required solution .
