As we know the property of charge that charge is always conserved
so we can say

here we know that total charge is

and we also know that

from above equation we can say


so the other charge will be -6 C
Answer:
The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.

I hope thats what u needed.
Answer:
F = 2985.125 N
Explanation:
Given that,
The radius of curvature of the roller coaster, r = 8 m
Speed of Micheal, v = 17 m/s
Mass of body, m = 65 kg We need to find the net force acting on Micheal. Net force act the bottom of the circle is given by :

So, the net force is 2985.125 N.
Answer:
Look at this picture this is the answer
Explanation:
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
as we know that angular acceleration of the wheel is given as

now the radius of the wheel is given as
R = 3.21 cm
so the tangential acceleration is given as



Part b)
frequency of the wheel at maximum speed is given as


now we know that

now radial acceleration is given as


Part c)
total angular displacement of the point on rim is given as

here we know that



now angular displacement will be


now the distance moved by the point on the rim is given as
