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
For the steady flow process, the first law is written like
DH + Du2/2 + gDz = Q + Ws
since there is no shaft work, Ws = 0
and flow is horizontal, Dz = 0
Therefore,
DH + Du2/2 = Q
substituting for the quantities,
(2726.5 - 334.9) x 1000 + (200^2 - 3^2)/2 = Q (in terms of J/kg)
Q = 2411.1 kJ/kg
Heat transferred through the coil per unit mass of water = 2411.1 kJ
Answer:
the skill level of players
Explanation:
Answer:
Explanation:
Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.
