The component of waves must have same frequency and phase.
when the component of waves vibrate at the same rate and attain maximum point at the same time, reinforcement of the waves amplitude occur to cause a constructive interference.However, when the two waves are out of phase where one is at minimum when the other is at maximum a destructive interference happens.
Answer:
The bicycle slows down because of the frictional force acting on the tyres of the bicycle. When this frictional force overcomes the force applied by paddling, the bicycle stops.
Answer:
Explanation:
<em>Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.
</em>

<em>
</em>
<em>(C) of comparable size, and also they emit far fewer carbon dioxide and other gasses that have
</em>
<em>
</em>
<em>(D) that have a comparable size, and also they emit far fewer of the other gasses having
</em>
<em>
</em>
<em>(E) that have a comparable size, as well as emitting far fewer of the other gasses having</em>
<em>A is the most appropriate statement above. Diesel engine consume less energy and release fewer gases than the gasoline engines .</em>
<em>Both engine(Diesel and gasoline) converts chemical energy to electrical energy.</em>
Answer:
9.8 secs
Explanation:
the ball is in the air so it takes 9.8 secs to get to the ground
Hi!
The answer would be ~ 3.58
<h3>Explanation</h3>
You will need to use the simple formula of finding the number of moles, given the mass of the compound, which is:
number of moles of compound = mass of compound / Mr of compound
The mass in this equation is the mass of the compound you have/ are considering.
The Mr is the sum of the atomic masses of each element in the compound.
<u><em>To proceed with this, you need to have two of the following values:</em></u>
Mass : 340g
Mr of MgCl2 : 95
Number of moles : ?
<u><em>Substituting the respective values in the equation:</em></u>
number of moles = mass / Mr
number of moles = 340 / 95
number of moles = 3.58
Hope this helps!
