Since the speed of the bag is constant, it’s kinetic energy remains constant. Since it’s height above the ground is constant, it’s gravitational potential energy is also constant. Since it’s total energy is constant, net work = 0.
Hello!
The chemical equation for this reaction is the following:
2HCl (aq) + Ca(OH)₂(aq) → CaCl₂(aq) + H₂O(l)
To determine the grams of Calcium Chloride formed, we will need to determine the moles of each reactant and divide by the reaction coefficient to know which is the limiting reactant (the one that is in the lowest amount):
So, the limiting reactant is HCl, so we'll use the following conversion factor to determine the mass of CaCl₂ produced:
So,
173,41 grams of CaCl₂ are produced.
Have a nice day!
Answer:
The order of the energy of the photons of given wave will be
= Ultraviolet waves > infrared waves > microwaves
Explanation:
where,
E = energy of photon
= frequency of the radiation
h = Planck's constant =
c = speed of light =
= wavelength of the radiation
We have :
(a) Frequency of infrared waves =
(b) Frequency of microwaves=
(c) Frequency of ultraviolet waves =
So, the decreasing order of the frequencies of the waves will be :
As we can see from the formula that energy is directly proportional to the frequency of the wave.
So, the order of the energy of the photons of given wave will be same as their order of frequencies:
= Ultraviolet waves > infrared waves > microwaves
