A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to.
Answer: SBb
On 1930 the astronomer Edwin Hubble classified the galaxies based on their visual appearance into elliptical, spiral and irregular, being the first two classes the most frequent.
So, according to this classification, the Milky Way is a barred spiral galaxy (SBb in Hubble's notation system) because it has a central bar-shaped structure of bright stars that spans from one side of the galaxy to the other. In addition, its spiral arms seem to emerge from the end of this "bar".
Scientifics considered this, after measuring the the disk and central bulge region of the galaxy, and the conclusion is the Milky Way fulfills these conditions, because is a galaxy that orbits on its same axis and with this rotation its arms are twisted in opposite directions around the mentioned axis.
P = VI
Power = Voltage x Current
Isolate for current
P/V = I
16/7 = I
I = 2.28 A
Answer:
a)
b)
c)
Explanation:
From the question we are told that:
Intensity I= 1.36 kW/m2=>1360W/m
b)Average mass per square meter m = 0.170 kg
c)
a)
Generally the equation for force per square meter is mathematically given by
b)
Generally the equation for force is mathematically given by
F=ma
Therefore
c)
Generally the Newton's equation for Motion is mathematically given by
change in velocity=final velocity-initial velocity=9-3=6m/s
acceleration=change in velocity/time
=6/3=2m/s²
