Explanation:
As ocean waves approach shore, their velocity decreases. The relation between the velocity, wavelength and the frequency of a wave is given by :
f = frequency
= wavelength
..............(1)
So, as the velocity of the wave increases, the wavelength and frequency also increases as per equation (1). When the velocity decreases, the frequency and the wavelength also decreases.
Answer:
polar molecules are molecules that have an unequal distribution of charges. nonpolar molecules, the type of covalent bond are equally shared between two atoms or elements producing no charged ends
Answer:
Explanation:
1 ) Average power supplied to an inductor is zero because the phase difference of potential and current is π / 2 .
So it is a wrong statement .
2 ) Step up transformer increases the voltage . At high voltage , lesser current is required to transport electrical energy . When current is reduced , the loss of energy due to heating effect is reduced .
3 ) voltage and current are in phase in resistance in ac .
3 ) RMS stands for Root Mean Square .
