Constructive interference means that the waves combine instead of negate. if they are both amplitude x, adding them together would result in 2x, or doubling the amplitude of one of the waves
A frequency spectrum shows a tone that is composed of a frequency of 440 h z, 880 h z, and 1320 h z. the 880 h z and 1320 h z frequencies are called. sine wave.
Frequency, in physics, the wide variety of waves that skip a hard and fast point in unit time; also, the variety of cycles or vibrations gone through for the duration of one unit of time via a body in periodic movement.
The variety of durations or often happening occasions of any given type in unit of time, typically in one 2nd. the variety of cycles or finished alternations in keeping with unit time of a wave or oscillation. symbol: F; Abbreviation: freq.
Frequency is an crucial parameter used in technological know-how and engineering to specify the temporal charge of change located in oscillatory and periodic phenomena, along with mechanical vibrations, audio indicators, radio waves, and mild.

Answer:
Explanation:
Let x be the horizontal distance of airplane . angle of elevation of airplane from observer = θ , altitude of airplane = 2000 ft ,
from the construction θ = 45 degree. , x = 2000 ft .
Tanθ = 2000 / x
sec²θ dθ / dt = (2000 / x²) dx / dt
dθ / dt = 2000 /(sec²θ x²) x dx / dt
dx / dt = 150 ft /s
dθ / dt = 2000x 150 /(sec²θ x²)
= 300000 / sec²45 x 2000²
= .15 degree/ s
Answer:
all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
Explanation:
Electrostatic interactions, have many rare manifestations in nature, which causes many reasons to study them.
- Lightning is a very striking form of electricity
- The biological processes are governed by currents of inanes and potential differences
- The transfer of nutrients and fertilizers to plants is with ion exchange, electrostatic forces
- all modern electronics is based on electricity
- the electric charge in very dry places, creates high currents that can create fires or kill people
In summary all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
Explanation:
It is given that,
Velocity of the particle is given by:
We need to find the magnitude of its acceleration at t = 3 seconds. We know that, acceleration a is given by :
At t = 3 seconds
So, the magnitude of a is given by :
So, the magnitude of acceleration is 13.7 m/s². Hence, this is the required solution.
