Answer: f = 392 hz
v = 343 m/s
wavelength = 343/392 = 0.875 m
hope this helped!
Answer:
For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped. So, a sound wave 's amplitude decreases as it moves through a medium.
Explanation:
The answer is 8.
The innermost shell can only hold 2 electrons, but the second shell (and other shells afterward) can hold 8 or more (depending on the level).
Sorry, I most likely did this wrong; but hopefully I didn't!
HgO2
Na+H2CI
K2CI2
C2H6O2--> H2CO2
C5H12O2--> H2CO3
A. It is the strongest force possible.
Explanation:
The force exerted on a charged particle moving in a region with a magnetic field is given by the following equation:
where
q is the magnitude of the charge
v is the velocity of the particle
B is the strength of the magnetic field
is the angle between the direction of the velocity and of the field
From the equation, we notice that:
- The force is maximum when the particle is moving perpendicular to the magnetic field, therefore when and
- The force is zero when the particle is moving parallel (or anti-parallel) to the magnetic field, therefore when and
Based on these observation, we can immediately conclude that the only correct option among the given choices is
A. It is the strongest force possible.
