Answer: 26 beats in 2 seconds
Explanation:
The number of beats per second = frequency of tuning fork 1 - frequency of tuning fork 2.
Given :
- frequency of tuning fork 1 = 500Hz
- frequency of tuning fork 2 = 487Hz
Thus,
Beats per second = 500 - 487
= 13 beats per second
Therefore in two(2) seconds, you will have 2 x 13 = 26 seconds.
Answer:

Answer:

Explanation:
The charge of a single electron is:

If a droplet contains N electrons, then its charge would be:

In this case, the droplet has
N = 6
electrons, so its total charge is

The velocity of the car after it accelerates for 25 seconds would be 820.2 ft/s or 250 m/s
