Answer:

B. Point D and E

Explanation:

Kinetic energy is the energy of motion and is proportional to velocity of the object and its mass. Mathematically,

K.E=\frac{1}{2} mv^2

where m is mass of object and v is the velocity of the object.The object while moving upwards, starts with a high initial velocity ,thus high kinetic energy. The kinetic energy starts to reduce at point B and its minimum at point C.Potential energy is the energy of an object related to its position. Mathematically,

P.E=mgh

where m is mass of object , h is the height of the object and g is acceleration due to gravity. At point C the potential energy is maximum due to the height attained by the object.As the object falls, the potential energy starts to reduce at point D and reaches its minimum value at point E where all potential energy is converted back to Kinetic energy.

wel
Stoich questions...

1) convert the grams of Au to moles
(33.5g)/(196.7g/mol)=___x___

2)find how many atoms are in that many moles by multiplying it by avogadro's number.

x(moles of Au)*(6.02*10^23)=?

3)now that you have found the number of atoms of gold, convert it to grams of aluminum by multiplying it by Avogadro's number and multiplying it by the atomic mass of aluminum.

What is the overall reaction order for this rate law: rate = k[A]2[B][C]?
dybincka [34]

Zero order are reactions in which concentration of reactant has NO effect on RATE OF REACTION.


2. First order are reactions in which concentration of one reactant is proportionate to the RATE OF REACTION.

Exp: That means when you increase the concentration of the one reactant, then the rate of reaction will increase by the same degree of extent.


3. Second order are reactions in which concentration of two reactant has an effect on the RATE OF REACTION.


Formula:

1. Zero order Rate = k

2. First order Rate = k(A)^m

3. Second order Rate = k(A)^m(B)^n


where () represents concentration

and equation is mA + nB -> Product.

What will happen to the final pressure of a cylinder when the volume is doubled.
OLEGan [10]

If temperature were to double the pressure would likewise double. Increased temperature would increase the energy of the molecules and the number of collisions would also increase causing the increase in pressure.

Calculate the MASS if the density is 2.34 g/mL and the volume is 12.50 mL.
AlexFokin [52]

Answer:

<h2>mass = 29.25 g</h2>

Explanation:

The denisty of a substance can be found by using the formula

Density =  \frac{mass}{volume}

Making mass the subject we have

<h3>mass = Density × volume</h3>

From the question

Density = 2.34 g/mL

volume = 12.50 mL

Substitute the values into the above formula and solve for the mass

That's

mass = 2.34 × 12.50

We have the final answer as

<h3>mass = 29.25 g</h3>

Hope this helps you
