The answer is: B. alloy.

The best choise in using low force (100 N, 200 N, 300 N) to move the ball is alloy, because it has the greatest distance (25 m, 30 m, 80 m).

One newton is the force needed to accelerate one kilogram of mass (in this example bat) at the rate of one metre per second squared in direction of the applied force.

Newton's second law of motion: F = m · a.

F -  force applied.

m - mass of the object receiving the force.

a - the acceleration of the object.

The correction answer is Alloy. If you look at the graph, and pay attention to the wording in the question, it says "using low force to move the ball." The best option for moving the ball with low force is Alloy. Hope this helps!

Dispersal of matter and energy can be directly related to spontaneity if the: Select the correct answer below
n200080 [17]

Answer:

d. there are no conditions for this correlation.

Explanation: Dispersal of matter is a term used to describe the various processes and activities involved in the transfer of materials from one location to another.

The spontaneity of a process tries to explain that a process will continue to occur when an initial force has been applied, it doesn't require the continous input of energy for it to continue to take place.

In the reaction MgCl2 + 2KOH Mg(OH)2+ 2KCI, if 3 moles MgCh are added to 4 moles KOH, what determines how much Mg(OH)2 is made?
gulaghasi [49]

Answer:-

KOH determines how much Mg(OH)2 is made.

2 mol of Mg(OH)2 formed

Explanation:-

The balanced equation is

MgCl2 + 2KOH --> Mg(OH)2+ 2KCI,

From seeing the coefficients we notice

2 mol of KOH reacts with 1 mol of MgCl2

4 mol of KOH reacts with 1 x 4 / 2 = 2 mol of MgCl2

3 moles of MgCl2 was added but only 2 mol react.

So we see there is excess MgCl2 .

Hence KOH is the limiting reactant.

So KOH determines how much Mg(OH)2 is made.

We see from the balanced chemical equation,

2 mol of KOH gives 1 mol of Mg(OH)2.

4 mol of KOH will give 1 x 4 /2 = 2 mol of Mg(OH)2.

To make a 0.500 M solution, one could take 0.500 moles of solute and add Group of answer choices enough solvent to make 1.00 kg
Fiesta28 [93]

<u>Answer:</u> The correct option is enough solvent to make 1.00 L of solution

<u>Explanation:</u>

A solution consists of solute and solvent. A solute is defined as the component present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

Molarity=\frac{Moles}{Volume} .......(1)

We are given:

Molarity of solution = 0.500 M

Moles of solute = 0.500 moles

Putting values in equation 1, we get:

0.500mol/L=\frac{0.500mol}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{0.500mol}{0.500mol/L}=1.00L

Hence, the correct option is enough solvent to make 1.00 L of solution
