The frequency of a sound wave or any wave for that matter is the reciprocal of the period. That is,
f = 1/T
Substituting the known value of period,
f = 1/(0.05 s)
f = 20 Hz
Thus, the frequency of the wave is equal to 20 Hz.
Answer:
(A) Series and Parallel
Explanation:
Circuit Component: These are electrical devices that makes up the circuit. They include, resistors, capacitors, inductors, voltmeters, ammeters, cell/batteries, earth connection, bulb, switch, connecting wire etc.
These component can either be connected in series or in parallel.
(1) Series Connection: This can be refered as end to end connection of electric component.
(2) Paralel Connection: This can be refered as the side to side connection of electric component.
From the question above,
A electric component in a circuit can be combined in series and in parallel.
The right option is (A) Series and Parallel
Some sort of magnetic metal
Metals are heavier per cubic unit than other materials such as air or water, and also are much more magnetic than other materials
Answer:
Friction
Explanation:
friction is the force that tries to slow things down when two things are rubbed together.
