Answer:
D. Decrease the radius of the swing in the circle
Explanation:
Decreasing the friction on the chain and increasing the radius of the swing in the circle will both increase the speed.
Cause the deeper you go ( for an example the ocean) the water pressure increases rapidly.
Answer:
The excess charge is
Explanation:
From the question we are told that
The diameter is 
The potential of the surface is 
The radius of the sphere is

substituting values


The potential on the surface is mathematically represented as

Where k is coulomb's constant with value 
given from the question that there is no other charge the Q is the excess charge
Thus

substituting values


Answer:
space , small amount of gravity is found in the space ,infact we can say that there is no gravity in the space
Explanation:
The balanced chemical equation is given as:
2H₂O₂ → O₂ + 2H₂O
А There are two peroxide molecules on the reactant side.
The statement is correct because the left hand side is the reactant side. We can read the reaction as;
2 molecules of hydrogen peroxide decomposed to given 1 molecule of oxygen gas and 2 molecules of water .
D Mass must be conserved so there are an equal number of molecules in the reactants and products.
E Mass must be conserved so there are an equal number of atoms in the reactants and products.
Since the chemical equation is balanced, choices D and E are correct. The reaction will have equal number of molecules and atoms on both sides of the expression.
