Answer:

\boxed{\bold { \large { \boxed {KE=\frac{1}{2} mv^2 \ , \ PE=mgh}}}}

Explanation:

Kinetic energy formula

\displaystyle KE=\frac{1}{2} mv^2

Potential energy formula

\displaystyle PE=mgh

\displaystyle KE \Rightarrow \sf kinetic \ energy \ (J)

\displaystyle PE \Rightarrow \sf potential \ energy \ (J)

\displaystyle m \Rightarrow \sf mass \ (kg)

\displaystyle v \Rightarrow \sf velocity \ (m/s)

\displaystyle g \Rightarrow \sf acceleration \ of \ gravity\ (m/s^2)

\displaystyle h \Rightarrow \sf height \ (m)

What is newton's second law of motion?
lord [1]

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

The amount of oxygen in the reactants is 4 atoms. In the products, the oxygen is distributed to water (H2O) and O2 gas. Which co
Reil [10]

Answer:

2 in front of water and 1 in front of oxygen

Explanation:

This question is describing balancing a chemical reaction. A balanced chemical reaction has the same number of atoms of each elements on both the reactant and product side. According to the question, the reactants contains 4 atoms of oxygen. The reactants give rise to water (H20) and O2 in the products side.

This reaction is most likely the decomposition of hydrogen peroxide (H2O2) as follows:

H2O2 (l) ----> H2O (l) + O2(g)

Based on the description, H2O2 will be 2H2O2 as it is said to contain four atoms of oxygen. This means that, in order to have a balanced equation, we must place coefficient 2 in front of water and coefficient 1 in front of oxygen. That is;

2H2O2 (l) ----> 2H2O (l) + O2(g)
