Answer
given,
x = (3.9 cm)sin[(9.3 rad/s)πt]
general equation of displacement
x = A sin ω t
A is amplitude
now on comparing
c) Amplitude =3.9 cm
a) frequency =
f = 4.65 Hz
b) period of motion
T = 0.215 s
d) time when displacement is equal to x= 2.6 cm
x = (3.9 cm)sin[(9.3 rad/s)πt]
2.6 = (3.9 cm)sin[(9.3 rad/s)πt]
sin[(9.3 rad/s)πt] = 0.667
9.3 π t = 0.73
t = 0.025 s
Answer: False, I think
Explanation:
Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.
Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction
Answer:
Ice cube, molecules, melting, zero degrees, liquid, faster, temperature, 100 degrees, steam
<u>Answer:</u> The correct answer is Option 3.
<u>Explanation:</u>
Amplitude of as sound wave is defined as the extent to which the air particles are getting displaced.
Speed of the sound wave is defined as the distance traveled by the sound wave per unit time and is not related to the amplitude of a sound wave.
Wavelength of the sound wave is defined as the difference between two crests or troughs.
Loudness of a sound wave is defined as the size of the vibration which are produced by it. This is closely related to the amplitude of the sound wave.
Pitch is defined as the sensation of the frequency. Higher the frequency, the pitch is also high and vice-versa.
From the above information, the amplitude of a sound wave is most closely related to the sound’s loudness.
Hence, the correct answer is Option 3.
The conversion factor needed to change from kilometers to meters is
D) 1000
Explanation:
The meter (m) is the SI units to measure distance.
The kilometer (km) is a sub-unit, where the prefix 'kilo' stands for 
, or 1000. This means that:
Therefore, if we have a length expressed in kilometers, we just need to multiply by 1000 to get the corresponding length in meters.
For instance, if we have a length of
L = 3.47 km
To convert in meters, we do:
