1) ________ is a force that you can fell with your feet

Physics
1 answer:
Kay [80]3 years ago
3 0

Answer:

1. Weight

2. potassium chlorate

3. pushing forward

Explanation:

1. Our full body stands in our feet, so feet takes all the weight of the body. In Newtonian mechanics, weight is a force. Weight is happened with the interaction between the mass and gravitational field. As the gravitational field is a vector, it has directions that are downward. So the interaction between mass and gravitational field works downward. So all the weight is felt by our feet.

2. In a fire stick, potassium chlorate is used. Potassium is known as a flammable chemical. Potassium chlorate is used in the upper part of the fire stick. When potassium chlorate faces frictions, a chemical reaction is happened, which creates great heat. The heat makes extra oxygen and heat, which makes the stick burn and create fire.

3. It is easy to rolling than push forward. If we consider a heavy lawn roller, the weight of the roller works downward. If we push the lawn roller, the force divided into two sub forces. One works downward which increases the weight of the roller and other works forward. But if we roll the lawn roller, the forces divided into two forces: upward and forward. Upward force makes the weight decrease and forward force makes it move forward. As the weight decrease, it becomes easy to roll than push

Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to
N76 [4]

The  energy of photon in kJ/mol is 329kJ/mol.

Wavelength of radiation is 370nm. The frequency of given wavelength is

            ν = c / λ

            ν = 3×10^8 / 370×10^-9

            ν = 8.11 × 10^14 s^-1

      Now the energy of photon is:

             E = hν

             E = 6.63×10^-34  J.s/photon × 8.11×10^14s^-1

             E = 5.41× 10^-19  J/photon

         To find in mole

              E = 5.41× 10^-19 × 6.022×10^23

               E = 3.29 ×10^ 5 J/mol

   So, the energy of mole of photon is equal to 329 kJ/mol.
