I am not sure if these are right, but I hope I helped (:
Answer:
Shift it to the left toward the reactants.
Explanation:
Le Chatelier's principle states that if a chemical system is in equilibrium and one of the factors involved in the equilibrium is altered (e.g temperature,pressure or concentration) ,the equilibrium will shift, so as to neutralize the effect of the change.
If a chemical system is in equilibrium, in which the reaction is exothermic and the temperature is being increased, the equilibrium will shift to left, favoring the backward reaction (reactants) as the constant K decreases.
<span>This phenomenon is known as illusion of attention and sometimes can include inattentional blindness. Basically, as humans, we are not used to backgrounds and people suddenly changing so our brains are not thinking to look for it.</span>
To solve this problem we will apply the concepts related to the Doppler Effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other.
Mathematically it can be described as
Where,
v = Speed of sound
f' = Reflected frequency
f = Emitted Frequency
= Speed of the object
Assuming that the speed of the medium is the speed of sound of 343m / s, we will then have that:
Answer: Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. There for the answer is A
