Answer:
0.82A
Explanation:
first we resolve the resistors in parallel
i.e 1/R=1/R1+1/R2
=1/R=1/6+1/3
1/R=1/2
R=2/1=2ohms
now we resolve all resistors in series
R=R1+R2+R3
R=6+3+2(the two parallel resistors we resolved are now in series with the others)
R=11ohms
From ohm's law V=IR
I=V/R=9/11= 0.82A.
Answer:
We see objects in a dark room due to the emission of light photons which are sensitive to our eyes. Darkness is simply a terminology used to describe the absence of light. Visible light to human is a component of the electromagnetic spectrum. Our eyes have receptors that picks the photons which light releases
Explanation:
Answer:
Fusion rates and star evolution increase rapidly because of the conversion of hydrogen molecules to helium.
Explanation:
At the early stage of a star mass, hydrogen atoms are produced. After a few billion years, these hydrogen atoms formed at the core of the star mass begin to fuse on the external side of the core. Hydrogen atoms get rapidly fused, resulting to a contraction of the star core, and as more hydrogen atoms get fused, helium atoms are formed.
This action results into rapid into a rapid and violent burning action of hydrogen atoms around the core.

See below
Explanation:
Set up your pendulum
measure its length and time the period ( you could time 100 of them and divide the time result by 100 to get the period, T)
then use
T = 2 pi sqrt (L/g) T = period L = length g = gravity
From the point of view of an observer located on the Earth - no.
Australia has the OPTUS satellites on the geostationary orbits.
