Answer: the answer is corect of what everone else said
Explanation:
It goes in this order. Medium, density, viscosity
Answer:
27.5 m/s
Explanation:
applying motion equations we can find the answer,
v = u + a*t
Let assume ,
u = starting speed(velocity)
v = Final speed (velocity)
t = time taken for the motion
a = acceleration
by the time of reaching the highest point subjected to the gravity , the speed should be equal to zero (only a vertical speed component is there)
for the complete motion it takes 5.5 s. that means to reach the highest point it will take 5.5/2 =2.75 seconds
we consider the motion upwards , in this case the gravitational acceleration should be negative in upwards (assume g=10 m/s2)
that is,
v = 0 , a = -10
, t =2.75
v = u + at
0 = u -10*2.75
u = 27.5 
Answer:
the volume occupied by air is not constant because as we add ethanol in it it will keep decreasing.
vapor pressure calculated and clausius-Claperon plot are affected because volume and vapor pressure are directly proportional.
Explanation:
by charle's law volume and temperature are directly proportional and vapor pressure is directly proportional to temperature thus volume and vapor pressure are also directly proportional by this relation
Answer:
contains many young stars
Explanation:
Irregular galaxies have <em>no definite shape</em>, which means that the first option is incorrect. They are definitely not round.
However,<u> they contain many young stars because the degree of star formation is fast.</u> They also contain old stars. Thus, the second choice is correct.
The "spiral galaxy" is the type of galaxy that has arms that extend from the center. These arms look "spiral," which influenced its name. This makes the last choice incorrect.
They are actually <u>smaller than the other types of galaxies.</u> This makes them <em>prone to collisions</em>. This makes the last choice incorrect.
