The charge on each coin is equal to
Given the following data:
Force = 2.0 Newton
Radius = 1.5 meters
To determine the charge on each coin, we would apply the law of electrostatic forces:
Mathematically, the law of electrostatic forces is given by the formula:
Note: (since the coin carry identical electric charges).
Therefore, the formula becomes:
Making q the subject of formula, we have:
Substituting the given parameters into the formula, we have;
I'm gonna have to assume the girl is on the right side and boy on left.
The net force is the sum of all forces on an object (includes negatives).
Let's say the force of the boy is variable <em>b</em>. Use the formula F = ma.
<em>b </em>+ 3.5 = 0.2(2.5)
This is now simple algebra. Solve to get that <em />the boty is exerting a force of -3N to the left.
As we know that speed of sound is
frequency of sound is
now we know that frequency of sound and speed of sound is related to each other by the following formula
<em>so wavelength of sound is 25 cm or 0.25 m</em>
Answer:
order of my age is 8 in seconds.
Explanation:
Suppose my age is 20 years.
Now, as we know that:
1 year has 365 days
1 day has 24 hours
1 hour has 60 minutes
1 minute has 60 seconds.
So my age in seconds will be:
Therefore the order of my age is 8 in seconds.
