When the sound waves have same wavelength, frequency and amplitude we just need the phase difference between them at a particular location to determine whether the waves are in constructive interference or destructive interference.

Interference is a phenomenon in which there is superposition of two coherent waves at a particular location in the medium of propagation.

When the waves are in constructive interference then we get a resultant wave of maximum amplitude and vice-versa in case of destructive interference.

For constructive interference the waves must have either no phase difference or a phase difference of nλ, where n is any natural number.

For destructive interference the waves must have a phase difference of n×0.5λ, where n is any odd number.

An empty parallel plate capacitor is connected between the terminals of a 18.8-V battery and charges up. The capacitor is then d

Basile [38]

Answer:

$p.d' = 37.6 V$

Explanation:

From the question we are told that:

Potential difference $p.d=18.8V$

New Capacitor $C_1=C_2/2$

Generally the equation for Capacitor capacitance is mathematically given by

$C=\frac{eA}{d}$

Generally the equation for New p.d' is mathematically given by

$C_2V=C_1*p.d'$

$p.d' = 2V$

$p.d'= 2 * 18.8$

$p.d' = 37.6 V$

Compare the physical sciences to the life sciences.

Elden [556K]

1.Life science involves fields of discipline catering to living organisms such as we humans while physical science caters to non-living organisms.

2.Life science has more fields of discipline than physical science.

3.Physical science relies on laws and theories to explain concepts while life science relies on biological explanations and can also rely on theories.
