There is large increase in temperature of the coffee due to the large amount of kinetic energy imputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system
Thermal energy is converted to chemical energy.
Explanation:
The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.
Water H₂O Hydrogen peroxide H₂O₂
Contrast
Water is a compound made up of 2 moles of hydrogen and 1 mole of oxygen
Hydrogen peroxide is made up of two moles of hydrogen and and 2 moles of oxygen.
Comparison:

Answer:
We apply an electric field in the negative y direction
Explanation:
Since A uniform magnetic field is in the positive z direction and A positively charged particle is moving in the positive x direction through the field, the magnetic force acting on the positively charged particle is in the positive y direction according to Fleming's right-hand rule.
For the net force on the particle to be zero, we apply an electric field in the negative y direction to create an electric force on the positively charged particle, so as to cancel out the magnetic force.
Answer: A wavelength is how long ONE wave is. First divide the distance of the whole diagram by the number of waves. you will get 2m. This is the answer.
