Answer:
Gravity (perhaps)
Explanation:
Without a further description or a diagram, I would guess the downward force would be gravity.
Running because kinetic energey is the engery created by motion
Answer:
4.26*10^37kg
2.14*10^7 solar mass
Explanation:
To solve this question, let us assume that the ring shaped accretion disk around the galaxy center's black hole is circular. This would permit us to use the circular orbit equation.
To find the mass of the disk, we use the formula
V = √(Gm/r)
2*10^5 = √[6.67*10^-11 * m / (7.5 * 9.461*10^15)]
(2*10^5)² = 6.67*10^-11 * m / 7.096*10^16
4*10^10 * 7.096*10^16 = 6.67*10^-11 * m
m = 2.838*10^27/6.67*10^-11
m = 4.26*10^37kg
To get the mass in solar mass, we divide by mass of the sun(as instructed)
m = 4.26*10^37/1.99*10^30
m = 2.14 * 10^7 solar mass
Answer:
the angle, in radians, between the central maximum = 2.87degree or 0.05radians
Explanation:
The detailed steps and appropriate formula is as shown in the attachment.
Using λm = dsin teta
where d =20λ, m = 1
from the formula, sin teta = λ/20λ
= sin teta = 0.05
teta = arc sin(0.05) = 2.87 degree
Using the information given in the question, we have no way to tell.
Is it an air current ? Is it a water current ? Is it an electric current ?
Are the springy iron strip and the current related somehow ?
Are they even on the same planet ? ?
