Answer:
Explanation:
Bulk modulus is defined as the relative change in the volume of a body produced by a unit of compressive acting uniformly over its surface:
Hence the density of the seawater at a depth of 680atm is calculated as:-
What solid-state components in a mobile phone maintain proper voltage levels in the circuits?
1 answer:
Answer:
Diodes helps in maintaining proper voltage levels
Explanation:
Electronic components such as diodes allow current to flow in forward biasing.
Under reverse biasing diode does not allow current to flow but a negligible amount of current does flow.
Forward biasing allow current to flow after crossing potential barrier .
When crossing this potential barrier we can observe an increase in current but the voltage does not go higher than . Even with the high input voltage.
Hence, diode maintains proper voltage in circuits.

The electrostatic force between the two ions is
Explanation:
The electrostatic force between two charged particle is given by Coulomb's law:
where
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, the ion of sodium has a charge of
while the ion of chlorine has a charge of
And the distance between the two ions is
Substituting, we find the electrostatic force between the two ions:
where the negative sign simply means that the force is attractive, since the two ions have opposite charge.
