You are riding your bicycle directly away from a stationary source of sound and hear a frequency that is 1.0% lower than the emitted frequency. The speed of sound is 343 m/s. What is your speed

Explanation:

Given

apparent frequency is 1 % lower than the original frequency

Speed of sound

suppose f is the original frequency  

apparent frequency

using Doppler's formula

where  

=apparent frequency  

=velocity of sound in the given media

=velocity of source

=velocity of observer

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

the answer is neither ball has a charge.
