Answer:
makes a transition from a high to a lower energy state
Explanation:
The emission spectrum is the spectrum of electromagnetic radiation emitted due to the transition from a state of high energy to a state of lower energy made by an electron in the atoms of the chemical element or compound. The emitted photons have an energy equal to the difference in energy between the two states.
You measure the distance between crest and crest or trough and trough
We are given the mass of an <span>aluminum sculpture which is 145 kg and a horizontal force equal to 668 Newtons. The coefficient of friction can be determined by dividing the horizontal force by the weight of the object. In this case, 668 N / 145 * 9.8 equal to coeff of friction of 0.47</span>
Answer:
B) Inertia is the resistance of any physical object
When Living things die,it takes them millions of years to form fossil fuels and as we are using more fossil fuels,the dead and decaying organisms cannot replenish the amount of fossil fuels humans are using as it takes a long time.Hence fossil fuels are not a renewable source of energy.
