Negative x ( -x) is the opposite of x
When x = 71, then -x would be -71
Answer:
d) F2 = -F1.
Step-by-step explanation:
According to Coulomb's law of forces on electrostatic charges, the force of attraction is proportional to the product of their charges, and inversely proportional to the square of their distance apart.
What this law means is that both particles will experience an equal amount of force on them, due to the presence of the other particle. This force is not just as a result of their individual charges, but as a result of the product of their charges. Also, the force is a vector quantity that must have a direction alongside its magnitude, and the force on the two particles will always act in opposite direction, be it repulsive or attractive.
The answer is 45 because I just had this question
Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2
7x-8=5x-2
+8 +8
-----------------
7x=5x+6
-5x -5x
----------------
2x=6
/2 /2
-----------
x=3
y=7x-8
y=21-8
y=13
Part B) The lines will intersect at point (3, 13), because idk it just makes sense
