A sound wave travels at 330 m/sec and has a wavelength of 2 meters. Calculate its frequency and period.
Answers
The frequency of the wave with a speed of 330 m/s and 2 meter wavelength is 165 Hz. The time period of the wave is then, 0.006 seconds.
What is frequency ?
Frequency of a wave is the number of wave cycles per second. Frequency of a wave is the inverse of its time period. It is inversely proportional to the wavelength and directly proportional to the speed.
Hence, ν = c/λ, where c is the speed.
The frequency of a sound wave is called its pitch.
Given that, c = 330 m/s
wavelength λ = 2 meters.
frequency = 330/2 = 165 s⁻¹ or 165 Hz.
The time period of a wave = 1/ frequency.
T = 1/165 = 0.006 s or 6 milliseconds.
Therefore, the frequency of the wave is 165 Hz and time period is 0.006 seconds.

Answer:
A.) gas is matter, and therefore has mass
Explanation:
The principle illustrated in this scenario is a. gas is matter, and therefore has mass.
When the air from one balloon is released, it creates a flow of gas in one direction. According to the principle of gas having mass, the released gas exerts a force on the hanger, causing it to tilt. This demonstrates that gas is matter and has mass.
It's important to note that gas does have volume, which can be measured. This is not the principle being illustrated in this scenario.
The principle of released gas having a higher temperature than inert gas is not applicable in this scenario, as no information is given about the temperatures of the gases involved.
The principle of matter may never be destroyed is a general principle in physics and does not specifically apply to this scenario.

#1). Define what 'the 'X is, and how it's related to the ball.
#2). Be clear on how 'the X' is related to the 'known velocity'.
#3). Identify how the 'known velocity' is related to the action of the ball when it's launched.
With this information in front of you, you'll have a much better chance

We can determine the speed of an object with only a tape measure and a stopwatch first by measuring the distance traveled by any given body and simultaneously measuring the time taken to cover this distance with the help of the stopwatch
What is speed?
The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.
The mathematical expression for speed is given by
speed = total distance /Total time
Suppose a body travels a total distance of 750 meters in a total time of 75 seconds, we can measure this distance with the help of a tape measure and the time with the help of a stopwatch its speed would be 4 meters/seconds
speed = distance measured by tape measure /stopwatch time
= 750/75
= 10 m/s
Thus, we can determine the speed of an object with only a tape measure and a stopwatch

B
THE EYE OF THE STORM IS CALM
Answer:
b. has warm, calm air and light winds
Explanation:
The eye of a hurricane is calm and "peaceful", it's the region with calm weather. But the eyewall is really dangerous, due to its pressure and speed difference. Actually, the eyewall has the most severe winds and weather. Another important characteristic is that the eye has the lower pressure.
So, among the options, b. is the right answer.
b. has warm, calm air and light winds
