Using Newton’s laws of motion, describe the motion of a roller coaster and analyze the forces acting on the roller coaster at di
Illusion [34]

We can apply Newton's third law of motion in roller coaster.

Explanation:

  • If we are planning to make a roller coaster with elevations and turn then we need to apply newton’s law of motions, kinetic energy and potential energy.
  • Newton’s third law of motion says that “ for every action, there is an equal and opposite reaction”. Newton’s third law of motion applies between the tract and ride vehicles.
  • If we neglect the air resistance and friction, Roller coaster car will always experience two types of forces which are gravitational force and normal force. The normal force is acting perpendicular to the track and gravitational for is also acting downwards.
  • Whenever the tracts get moving the gravitational force is attracting roller coaster to downward. So this will get accelerates. In the majority of the roller coasters, the hill will decrease with height as the train moves along the tract.

3. Humans discovered how to use fire and tools. How was this knowledge passed along to younger generations?
vlabodo [156]

Communication skills were developed so knowledge could be passed along to younger generations.

<h3>How knowledge will pass through generations?</h3>

Knowledge will pass from one generation to another with the help of education. The skill people give education to their youngers about fire and tools. In this way, skills of fire and tools pass from one generation to another.

So we can conclude that communication skills were developed so knowledge could be passed along to younger generations.

How do you write a balanced chemical equation for the reaction in which dinitrogen pentoxide gas reacts with water to produce ni
Dominik [7]

Answer: a)  N_2O_5(g)+H_2O(g)\rightarrow 2HNO_3(g)

b)  3.8608 moles

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced reaction for dinitrogen pentoxide gas with water to produce nitric acid is:

N_2O_5(g)+H_2O(g)\rightarrow 2HNO_3(g)

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

\text{Number of moles of dinitrogen pentoxide}=\frac{208.48g}{108g/mol}=1.9304moles

According to stoichiometry:-

As nitric acid is the limiting reagent as it limits the formation of product.

1 mole of N_2O_5 gives = 2 moles of HNO_3

Thus 1.9304 moles  of N_2O_5 give =\frac{2}{1}\times 1.9304=3.8608 moles of HNO_3

Thus 3.8608 moles of HNO_3 can be produced.
