3 is 3, 4 is 3, 5 is 3, 6 is false, 7 is true, 8 is false, 9 is false, 10 is 3
Answer:
-
Both exceed the matter-energy equivalent of luminous matter
- Dark matter has only an attractive gravitational effect, while the dark energy is repulsive in nature
Explanation:
Dark matter is defined as the matter which consists of about 85% of the total matter of the universe and is no-baryonic in nature.
It is attractive in nature and exerts gravitational pulling effect. Even individual galaxies are under the influence of dark matter. It is way more powerful than the visible matter.
Dark energy is that form of energy which is said to be responsible for the universe's expansion and is repulsive in nature
<span>77.2 k is -195.95 C
To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. So the expression becomes
c = 77.2 - 273.15 = -195.95</span>
Carbon is found in the solid form in geosphere of our earth. Coal and oil are some of the examples of materials containing carbon in the geosphere. when the coal or oil is burnt, carbon dioxide is formed and released in atmosphere. This carbon dioxide is absorbed by the water of the hydrosphere with the help of algae and plankton. The water turns acidic in nature. This way carbon is transferred from geosphere to hydrosphere.
a. The disk starts at rest, so its angular displacement at time 
is
It rotates 44.5 rad in this time, so we have
b. Since acceleration is constant, the average angular velocity is
where 
is the angular velocity achieved after 6.00 s. The velocity of the disk at time is
so we have
making the average velocity
Another way to find the average velocity is to compute it directly via
c. We already found this using the first method in part (b),
d. We already know
so this is just a matter of plugging in 
. We get
Or to make things slightly more interesting, we could have taken the end of the first 6.00 s interval to be the start of the next 6.00 s interval, so that
Then for 
we would get the same 
.
