Answer:
They both are part of electromagnetic radiation.
Radio waves have longer wavelength than visible waves.
Radio waves have lower frequency than visible waves.
Explanation:
I think the correct answer would be the child quietly sits until the timer goes off. It is ineffective because the child would be used to this process and would come to a time where he will not get something from it.Also, it would make a child feel isolated and alone which would affect hi self-esteem in a long run.
Answer:
Explanation:
Let assume the first connect have resistor R1 and R2
Then, this are connected in parallel
But, parallel connection of resistor have the same voltage.
So the power dissipated in each resistor is given as
P1=V²/R1
P2= V²/R2
If another resistor is added in parallel nothing change by the way each resistor dissipate power
Then, power dissipated in R3 is
P=V²/R3
Why we use parallel circuit at home
Parallel circuits are used in homes because the loads can be operated independently of each other.
Each load gets the full voltage of the circuit.
