Answer:
9,940 K
Image result for What is the surface temperature of Sirius B and A, in kelvins?
The bright component of the binary is a blue-white star 25.4 times as luminous as the Sun. It has a radius 1.71 times that of the Sun and a surface temperature of 9,940 kelvins (K), which is more than 4,000 K higher than that of the Sun

The ship's average speed during the 12 seconds is
(1/2) (58 + 153)
= (1/2) (211 m/s)
= 105.5 m/s .
Traveling for 12 seconds at an average speed of 105.5 m/s ,
the ship covers
(12 sec) x (105.5 m/s)
= 1,266 meters during the acceleration
Answer:True
Explanation:
We know that frequency in a tight string is given by
where
and velocity is given by
As increases v also increase but wavelength remain same because ends of string are fixed.
Answer: 60m/s
Explanation:
From the diagram:
Θ = 30°
Vertical resolution (y-axis) :
Voy = VoSinΘ
g in the upward direction = negative (-) = - g
Vfinal = 0
Distance (H) traveled along y =
Time taken to reach maximum height :
From v = u + at
0 = usinΘ - gt
gt = usinΘ
t = usinΘ / g
Horizontal resolution:
S = ut + 1/2at^2
Substituting t = usinΘ / g ; Voy = usinΘ
S = (usinΘ × usinΘ / g) - 1/2 g × (usinΘ /g)^2
S = (u^2sin^2Θ / g) - (u^2sin^2Θ / 2g)
S = (u^2sin^2Θ) / 2g
Now if S = maximum height = 45m
Then,
45 = [Vo^2sin^2(30°)] / 2(10)
45 =[ Vo^2 * (0.5)^2] / 20
45 =( Vo^2 * 0.25) / 20
20 * 45 = Vo^2 * 0.25
900 / 0.25 = Vo^2
3600 = Vo^2
Vo = sqrt(3600)
Vo = 60m/s
Answer:231.16 N/C
Explanation:
Given
Electric Flux
Area(A)
Given Field point above
Therefore angle between Area vector Electric Field =90-31.6=
We know that Flux is given by
E=231.16 N/C
