The relation between volume and temperature is direct, this is the higher the temperature the higher larger the volume.
Therefore, if you want that your gas occupies a larger volumen, you should increase the temperature, assuming other conditions (pressure and number of moles) remain unchanged.
The new temperature may be calculated using the proportion:
V1 / T1 = V2 / T2
=> T2 = V2 * T1 / V1
T1 and T2 are in absolute degrees, so T1 = - 73 + 273.15 = 200.15 K
=> T2 = 360 ml * 200.15 K / 210 ml = 343
Answer: the temperature should be increased to 343 K
Answer:
a) -1.14 rev/min²
b) 9900 rev
c) -9.92×10⁻⁴ m/s²
d) 30.8 m/s²
Explanation:
First, convert hours to minutes:
2.2 h × 60 min/h = 132 min
a) Angular acceleration is change in angular velocity over change in time.
α = (ω − ω₀) / t
α = (0 rev/min − 150 rev/min) / 132 min
α = -1.14 rev/min²
b) θ = θ₀ + ω₀ t + ½ αt²
θ = 0 rev + (150 rev/min) (132 min) + ½ (-1.14 rev/min²) (132 min)²
θ = 9900 rev
c) The tangential component of linear acceleration is:
a_t = αr
First, convert α from rev/min² to rad/s²:
-1.14 rev/min² × (2π rad/rev) × (1 min / 60 s)² = -1.98×10⁻³ rad/s²
Therefore:
a_t = (-1.98×10⁻³ rad/s²) (0.50 m)
a_t = -9.92×10⁻⁴ m/s²
d) The magnitude of the net linear acceleration can be found from the tangential component and the radial component:
a² = (a_t)² + (a_r)²
The radial component is the centripetal acceleration:
a_r = v² / r
a_r = ω² r
First, convert 75 rev/min to rad/s:
75 rev/min × (2π rad/rev) × (1 min / 60 s) = 7.85 rad/s
Find the radial component:
a_r = (7.85 rad/s)² (0.50 m)
a_r = 30.8 m/s²
Now find the net linear acceleration:
a² = (-9.92×10⁻⁴ m/s²² + (30.8 m/s²)²
a = 30.8 m/s²
Answer:
B
Explanation:
the amplitude is the distance from the resting point to the crest/trough.
The answer is a matter of opinion, and you're going to get different answers
from different people. Here's <u>my</u> take on it:
The writers, producers and advertising sponsors of these shows certainly
don't think they're boring. And <em><u>definitely</u></em> neither do the TV networks that
decide which ones to broadcast.
I'm not trying to say "The experts don't think they're boring, so you must
be wrong". I'm trying to say that different people have different opinions
about the same shows, and in <em>your</em> case,<em> you</em> find them boring.
My conclusion is this:
I think you're finding TV shows boring nowadays because you're growing
as a person. You've grown, developed, and matured to the point where
you're above the level of audience that the shows are pitched for. That's
a very good thing !
You're sad because you used to get pleasure and entertainment from TV,
and now it doesn't give you those things. That's like losing an old friend,
that you used to have such fun playing with, but he just doesn't do it for
you any more.
Now that you've grown up, you've made new friends. With them, you do
things that you wouldn't even understand with your younger friends. And
you develop new interests, like ... I don't know ... books, movies, hobbies,
your church, your profession, learning new things, developing new skills,
exercising your brain, writing, volunteer work, ham radio, building fine
furniture, singing, learning to write music, raising tropical plants, sculpture,
politics ... whatever turns you on. Some people never grow past the stage
where staring at the tube is all they need in life, because they don't have
what it takes to be interested in anything else. Those are the people that
TV is aimed at. But you have more, and that's why TV isn't enough for you.
There are other possible reasons why TV bores you. But until I know more
about you, I think it's a very, very good sign.
