Answer:
a binary phase or binary compound is a chemical compound containing two different elements. Some binary phase compounds are molecular, e.g. carbon tetrachloride. More typically binary phase refers to extended solids.
Newton's first law says that an object at rest will stay at rest, while an object in motion will stay in motion unless acted upon by an outside force.
A great example of this is a ball sitting on the ground. The ball will not move until some force is used on it, rather that be you kicking it, the wind blowing it, etc. Once that force is used against it, the ball will continue to move until gravity, air resistance, a friction bring it to a stop.
Answer:
Explanation:
We shall apply law of refraction which is as follows
sin i / sinr = μ , where i is angle of incidence , r is angle of refraction and μ is refractive index
here i = θa = 22.5°
r = θb
μ = 1.77
sin22.5 / sinθb = 1.77
.3826 / sinθb = 1.77
sinθb = .216
θb = 12.5 °.
Answer:
the total travled is 2.75
Explanation:
because if you divide 110 by 40 you get 2.75
The first requirement is to
look at all the vital information’s given in the question. Based on those
information’s the answer to the question can be easily reached.
Distance that needs to be covered for the race = 38.4 kilometer
Time required to complete the race = 4.5 hours
Then
Average speed = Distance/Time
= 38.4/4.5 km/hour
= 8.53 km/hr
So the average speed would be 8.53 Km/hr.
I hope the answer to the
question is what you were looking for and the procedure is clear to you.
