Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
Answer:
The correct option is D
Junction diodes are preferred over point-contact diodes for most purposes.
Explanation:
Point contact diode:
This type of diode is constructed by touching a metallic wire with an N-type semiconductor to form a small area of contact, hence the name point contact diode. The switching speed of these diodes is better than a conventional diodes.
These diodes are not usually preferred due to their low current ratings and poor reliability.
P-N junction diode:
This type of diode is constructed by joining two regions of opposite conductivity N-type and P-type material, a PN-junction is formed which allows the current to flow in one direction only. The conversion of AC current to DC is done by this process called rectification.
Answer:
Image result for Solvation in water is called
Solvation describes the interaction of solvent with dissolved molecules. ... Solvation involves bond formation, hydrogen bonding, and van der Waals forces. Solvation of a solute by water is called hydration.
Explanation:
Answer:
D. The net electrical charge of the Earth.
Explanation:
All the other three choices affect the gravitational force. I remember from middle school.
Answer:
the current flowing through the filament would be 5 amperes.
Explanation:
we know that according to OHMS law
V=I×R
where i is the current and R is the resistance and V is the voltage
applying the values in the formula
We get I = 5 A.
