A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity

Answers

Answer 1

Answer:

The final velocity of the motorcycle is 64.7 m/s

Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation

Explanation:

Using the equation of motion that contains all the given values in the question: v² = u² + 2as

where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance

v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m

v² = 0² + 2 * 4.55 * 460

v² = 4186

take square root of both sides

v = 64.7 m/s

Therefore, the final velocity of the motorcycle is 64.7 m/s

how many moles of Fe(OH)2 are required to produce 7.4 moles of Fe3(PO4)2

Answers

Answer:

22.2 mol

Explanation:

Considering the reaction stoichiometry, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

The balanced reaction is:

3 Fe(OH)₂ + 2 H₃PO₄ → Fe₃(PO₄)₂ + 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Fe(OH)₂: 3 moles H₃PO₄: 2 molesFe₃(PO₄)₂: 1 mole H₂O: 6 moles

Then you can apply the following rule of three:  if by reaction stoichiometry 1 mole of Fe₃(PO₄)₂ requires 3 moles of Fe(OH)₂, 7.4 moles of Fe₃(PO₄)₂ require how many moles of Fe(OH)₂?

[tex]amount of moles of Fe(OH)_{2} =\frac{7.4 moles of Fe_{3} (PO_{4} )_{2} x3moles of Fe(OH)_{2} }{1mole of Fe_{3} (PO_{4} )_{2} }[/tex]

amount of moles of Fe(OH)₂= 22.2 moles

Finally, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

A man walks 20 meters in 10 seconds. What is the speed? *

Answers

Answer: 2m/s.

Explanation: To find a speed/rate, you use the equation d = r*t. We switch around this equation to get r = d/t. Then, we plug in the numbers. r = 20 meters/10 seconds. Thus, the rate/speed is 2 meters/second (2m/s).

A man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).

What is the speed?

Speed is something to measure the intensity of anything like any object which is moving from one place to another place and can be calculated by dividing the traveled distance by the time taken by the object.

To calculate the speed of man the given values are distance and time  20 meters in 10 seconds respectively.

                      speed = distance / time

substituting the value in equation,

               speed = 20/10  

               speed = 2 meter per second (m/s)

Therefore, a man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).

An object has a mass of 441 g and a volume
of 10 cm3. What is the density of the object
in g/cm3?

Answers

The density is the ratio of the mass to the volume. The density of the object is 44.1 g/cm³.

What is density?

Density (ρ) is the quantitative measurement of the substance having grams of mass that are dissolved per cubic meter of the solution. The density is calculated as:

ρ = M ÷ V

Given,

Mass of the object = 441 gm

The volume of the object = 10 cubic meter

Density is calculated as:

ρ = 441 ÷ 10

= 44.1 g/cm³

Therefore, 44.1 g/cm³ is the density of the object.

If 175 grams of lead (ll) iodide is produced from the reaction, how many moles of potassium nitrate are produced?

Equation: 2KI + Pb(NO₃)₂ = 2KNO₃ + Pbl₂

Answers

Moles of potassium nitrate produced : 0.76

Further explanation

The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

2KI + Pb(NO₃)₂ ⇒ 2KNO₃ + Pbl₂

MW KNO₃ : 101.1032 g/mol

MW Pbl₂ = 461,01 g/mol

175 grams of Pbl₂ , mol :

[tex]\tt mol=\dfrac{175}{461.01}=0.38[/tex]

mol ratio KNO₃ : Pbl₂ = 2 : 1, so mol KNO₃ = 0.38 x 2 = 0.76

Mass of KNO₃ :

2. Platinum metal has a density of 21.4 g/mL. If the block measures 3 cm, by 0.03 m, by 40 mm
how much does it weigh in milligrams?

Answers

Answer:

80mg

Explanation:

Given parameters:

Density of Platinum metal = 21.4g/mL

Dimension of the metal  = 3cm by 0.03m by 40mm

Unknown:

Weight of the metal in milligrams?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

          Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the platinum metal  = l x w x h

 Let us convert the dimension of the metal to the same unit;

            3cm x 0.03m x 40mm

    convert to cm;

           100m = 1cm

           0.03m  = [tex]\frac{0.03}{100}[/tex]   = 0.0003cm

     -- 40mm;

            1mm = 0.1cm

           40mm  = 40 x 0.1  = 4cm

Volume of the metal  = 3 x 0.0003 x 4  = 0.0036cm³

1mL = 1cm³; so volume  = 0.0036mL

     Mass of the metal  = 21.4 x 0.0036  = 0.08g

       1g  = 1000mg

     0.08g  = 0.08 x 1000 = 80mg
