Answer:
Explanation:Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink. There are radioactive gases in the air we breathe. Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements.
(2.0 x 10² N/Coul) x (-1.6 x 10⁻¹⁹ Coul) = -3.2 x 10⁻¹⁷ N
The magnitude is 3.2 x 10⁻¹⁷ Newton.
I think the answer would be letter B.
Answer:
Explanation:
It is said to be in equilibrium about the fulcrum . It is the principle of moments.
Answer:
A balanced equation
Explanation:
when atoms of various elements or compounds react, they do this in mole ratio. It is a law to always balance the number of elements of each element on the reactant side to the corresponding elements on the product side of the equation. This is done by the introduction of coefficients.
