Answer:
0.73 N to 2 dp.
Step-by-step explanation:
F = k/d^2 where k is a constant , F = force and d = distance.
Substituting:
0.36 = k / (6)^2
k = 36*0.36 = 12.96 s the equation is F = 12.96 / d^2.
When d = 4.2 :
F = 12.96 / 4.2^2
F = 0.73 Newtons to 2 dp.
C. −6, is the best option
Answer:
Step-by-step explanation:

Product of a number and its multiplicative inverse should be equal to 1.
So,


As, 

=0.301029+0.845098+1.13943
=2.26007
=2.260(approximate)
This is an easy solution heres the answer 14-24= -10
Remember you can do 24 - 14= 10 but add a negative to the answer
