A = a is an example of Commutative Property.
I hope this helps you out Aydria01!
The formula is E= kQ/ d^2
k is 9x10^9
i changed 15 cm to 0.15 m
=> 9x10^9 x 12 OVER (0.15)^2
the answer is 4.8x10^12 N/C
but this is the electric field.
to find electric field STRENGTH, it’s E= F/q and you did not give a value for the force
None of them are like terms you have 5a 5b and 4
Steps:
Question 1:
Step 1: Multiply both sides by h+0.5.
Step 2: Factor out variable f.
Step 3: Divide both sides by h^2+0.5h.
Question 2
Let's solve for g.
Step 1: Divide both sides by h.
Answers:
1: f=45h+42.5/h²+0.5h
2: g=16.5h+53.25/h
