Answer:
1. Their temperature and luminascity
2. The sun
3. Main sequence (im not sure of the answer tho)
4. Because of the color the white dwarfs are white and the sun in and orange/red color
5. Blue giants
<em>~I hope this helps! Peace :D</em>
1: surface temperature
2: red giant
3: The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
4: A white dwarf is very dense
5: red giant
plz mark me as brainliest :)
4m/s²
Explanation:
Initial velocity (u) = 0 m/s
Final velocity (v) = 8 m/s
Time taken (t) = 2 sec
Acceleration (a) = ?
We know
Hope it will help :)
drag
drag is the force that acts against any moving object.
if it takes him any amount of time to get from one speed to another, it is caused by drag.
More quiclky
In Earth, there is a gravitional force. So that forces pushed you down faster.
(a) V1 = 8990.00 V
V2 = 8960.13 V
Parameters given:
q =3 mC
k = 8.99 * 10⁹ Nm²/C²
x1 = 3 m
x2 = 3.01 m
Electric potential is given as:
V = kq/r
Where
k = Coulombs constant
q = charge
r = distance
Potential at x1 is:
V1 = (8.99 * 10⁹ * 0.000003)/(3)
V1 = 8990.00V
Potential at x2 is:
V2 = (8.99 * 10⁹ * 0.003)/(3.01)
