Explain how potential energy and kinetic energy are transformed in a roller coaster.

Chemistry
1 answer:
spayn [35]3 years ago
4 0

Answer:

In the beginning, a roller coaster is still which means the forces acting upon the roller coaster are equal. But then as the rollar coaster starts to move upwards, the potential energy changes into kinetic energy since it is in motion. When the roller coaster reaches the top and stops, its kinetic energy immeadiately transforms into potential energy because it has potential to move and go fast. As the roller coaster descends, the potential energy transforms into kinetic energy. Hope this helps!

One type of electromagnetic radiation has a frequency of 107.1MHz,another type has wavelength of of 2.12x10^-10 m,and another ty
Andreas93 [3]

Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency

  • FM Radio waves < Visible light < X - rays
  • Order of increasing frequency.
  • FM Radio waves < Visible light < X - rays

This is further explained below.

<h3>What is electromagnetic radiation?</h3>

Parameters

Frequency =107 100 000 hertz

Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m

Energy = 3.97 * 10 -19 J/ photon.

Generally, the equation for Wavelength is  mathematically given as

λ = h c / E

Therefore

λ =6.626 * 10-34  * 3 * 108  / (3.97* 10 -19 J)

λ =5 * 10-7 m

In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.

  • FM Radio waves < Visible light < X - rays
  • Order of increasing frequency.
  • FM Radio waves < Visible light < X - rays

S + 6 HNO3 H2SO4 + 6 NO2 + 2 H2O
exis [7]

Answer:

              101.50 g H₂O

Explanation:

The mole ratio of HNO₃ and H₂O is 6 : 2

Hence, 16.9 moles of HNO₃ will produce = 2/6×16.9 = 5.63 moles of H₂O

Also,

Mass = Moles × M.Mass

Mass = 5.63 mol × 18.02 g/mol

Mass = 101.50 g H₂O

Name any <br>three kinds of mixtures with example​
sleet_krkn [62]

Answer:

Here are a few more examples:

Smoke and fog (Smog)

Dirt and water (Mud)

Sand, water and gravel (Cement)

Water and salt (Sea water)

Potassium nitrate, sulfur, and carbon (Gunpowder)

Oxygen and water (Sea foam)

Petroleum, hydrocarbons, and fuel additives (Gasoline)

Heterogeneous mixtures possess different properties and compositions in various parts i.e. the properties are not uniform throughout the mixture.

Examples of Heterogeneous mixtures – air, oil, and water, etc.

Examples of Homogeneous mixtures – alloys, salt, and water, alcohol in water, etc.
