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.

The answer is A.
When a substance is a gas, it fills its container no matter how many particles it's made of, however the number of particles present will directly affect the pressure and temperature of the system.
Answer:
70 mph
Explanation:
We can write the position of the car at time t as
where is the speed of the car, while the position of the truck is
where
is the initial distance between the car and the truck (at 3:00 pm)
is the speed of the truck
The car overcomes the truck when they have same position, so
This occurs at 4:30 pm, so 1:30 h (1.5 h) after the initial instant. So, by using
t = 1.5 h
And solving the equation for , we find the speed of the car:
Answer:
D. Alpha
This is because it's unlikely for it to reach living cells inside the body
