Answer:The wavelength of a 1-kHz sound traveling in water would be 150 cm.
Explanation:This is because in the equation, v(velocity) = 1500 m/s, and f (frequency) = 1 kHz.
Answer:
It's constant everywhere in its trajectory.
Explanation:
the projectile was launched with an initial velocity, the only acceleration that is affecting the projectile's velocity is gravity.
The acceleration of gravity is practically equal everywhere on earth, so during its trajectory, we have to take into consideration only the acceleration because of gravity.
This is only correct because the projectile was launched with an initial velocity and it's not accelerating from rest and then falls.
Answer:
This is a chemical property. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal.
Answer: the radial distance between the 500-v equipotential surface and the 1000 v surface will be 8.91*106 times the charge Q.
Explanation: To find the answer, we have to know more about the equipotential surfaces.
<h3>What are equipotential surfaces?</h3>
- An equipotential surface is the locus of all points which have the same potential due to the charge distribution.
- Any surface in an electric field, at every point of which, the direction of electric field is normal to the surface can be regarded as equipotential.
- We have the equation for electric potential as,
, where k is equal to 1/(4π∈₀) = .
- equation for radial distance will be,
<h3>How to solve the problem?</h3>
- For the first surface, we can write the equation of potential as,
- For the second surface, we can write the equation of potential as,
- Thus, the radial distance will be,
Thus, we can conclude that, the radial distance between the equipotential surface of 500V and 1000V will be,8.91*106 times the charge Q.
