Answer:
Each part so obtained will represent the fraction 1/8 and the number line obtained will be of the form: To mark 3/8; move three parts on the right-side of zero. To mark 5/8; move five parts on the right-side of zero. To mark -1 3/8 i.e. -11/8; move eleven parts on the left-side of zero.
Explanation:
Given that,
Output power = 87 W
Decibel reading = 120 dB
We need to calculate the intensity of sound
Using formula of intensity of sound
Put the value into the formula
We need to calculate the distance
Using relation of power out[ut and intensity
Put the value into the formula
Hence, The distance is 2.63 m

The phase angle ф for the source voltage relative to the current the and Frequency is 192.14 H.
Phase angle b/w VL and inductor is 90°
Angular frequency, w = 2 pi f
VL = I XL
Frequency, f = VL/2 pi L I = 49/(2 pi x 4.25 x 0.00955) = 192.14 Hz.
The formula = 2/T yields the angular frequency. In radians per second, the angular frequency is expressed. The frequency, f = 1/T. the reciprocal period. The number of full oscillations per unit of time is given by the motion's frequency, f = 1/T = /2. Angular frequency and velocity are related to displacement and revolution velocity, respectively. full response Angular frequency is a scalar measure of rotation rate, also known as angular speed, radial frequency, circular frequency, and orbital frequency.
