From Columb's Law which describe the electrostatic interaction.
The formula is given and looks as follows
where:
F is force acting between charges,
q1 - charge one given in columbs,
q2 - charge two given in columbs,
r - distance between charge in meters
k - constant
First, we have to convert out formula to get r.
Now we multiplaty by
both sides of equation
Now we devide both sides by F
Next step is take square root
We have all date, we can subsitute it to our formula
Answer:
The body reading on the scale will increase.
Explanation:
The scale reading will definitely increase due to buoyancy of the ball. According to Archimedes' law which states that the magnitude of buoyancy force on the body is the same as the weight of the liquid which is pushed out when submerging the body. Therefore, the body reading on the scale will increase.
The asnwer to your question is A
Answer:
Fred's annual payment = $ 2880
Explanation:
Given that,
The total insurance premium of Fred annually, P = $ 7,200
This premium amount is divided among Fred and his employer.
His employer pays 60 % of the premium and the remaining 40% is paid by Fred annually.
So, the amount paid by Fred is
( 7200/100) x 40 %
= 2880
So, Fred's share of the premium to be paid annually is $2,880
