Answer:
Frequency of sound wave = 198.83 hertz (Approx.)
Explanation:
Given:
Velocity of sound wave in air = 340 m/s
Wavelength = 1.71 meter
Find:
Frequency of sound wave
Computation:
Frequency = Velocity / Wavelength
Frequency of sound wave = Velocity of sound wave in air / Wavelength
Frequency of sound wave = 340 / 1.71
Frequency of sound wave = 198.8304
Frequency of sound wave = 198.83 hertz (Approx.)
Explanation:
The given data is as follows.
Electric field (E) = 
Charge (e) = 
C
Formula to calculate the magnitude of force is as follows.
F = qE
= 
= 
Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is .
When temperature decreases the atoms(or molecules) within the substance begin to slow down.
Answer:
1.8L
Explanation:
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.
So x is the volume at pressure 235
235x = 101(4.2)
x = 424.2/235 = 1.8
Answer:
23
Explanation:
The line starts at 31, it then drops down to about 23. It then drops even more to about 14. It then raises to 20 and then raises to 23.
Hope this helps!
