Given the sets A = {-4, -1, 3, 5, 9} and B = {-2, -1, 0, 1, 2, 3}, the set AUB (u is upside down) is given by:
ki77a [65]
The upside down U is the symbol for the intersection of sets. The intersection of two sets is the set that contains the elements that are common to both sets. Which elements are both in set A and in set B?
Answer: {-1, 3}
Hey I would try to use Socratic or photomath they are apps
The charge Q is 512 c.
Step-by-step explanation:
Step 1:
The equation is 
, where q and Q are the charges, R is the distance between the charges, and F is the force between the charges.
From the question, we have;
F = 40 Newton, R = 16 m and q = 20 C.
We need to calculate Q.
Step 2:
By substituting the values of F, R, and q in the equation, we get
.
We cross multiply to solve Q.
So Q = 512 C.
