<em>Power = (voltage) x (current)</em>
We don't actually know what power<em> rating</em> may be marked on the bulb or the package it comes in, but the power it actually consumes and dissipates, when connected to a 15V battery, is . . .
Power = (15 V) x (3.0 A) = <em>45 watts</em>
Answer:
Explanation:
Time to cover first 100 km = 1 hour.
time remaining = 3.15 - 1 = 2.15 hour .
Time to cover next 42 km = 1 hour .
Time remaining = 2.15-1 = 1.15 hour.
Distance to be covered = 310 - 142
= 168 km
least speed needed = distance remaining / time remaining
= 168 / 1.15
= 146.08 km / h .
Explanation:
K in chromatography is defined as a partition coefficient. It is an equilibrium constant that determines the measure to which the solutes partition between two phases.
K = Cm/Cs
where Cm is solute concentration in mobile phase
Cs is solute concentration in stationary phase
When K is more, then it implies that the solute concentration in the mobile phase is more in chromatography test.
One of the brightest nebulae in the night sky, the Orion Nebula may be seen with the unaided eye. The Trapezium is a young open cluster of four main stars in this magnitude 4 interstellar cloud of ionized atomic hydrogen.
<h3>What is the source of the Orion Nebula's crimson glow?</h3>
- The hydrogen gas in the Orion Nebula, which is powered by radiation from young stars, gives off a crimson tint. The nebula's blue-violet regions are reflecting radiation from bright, blue-white O-type stars while the red areas are emitting light.
- The Orion Nebula is one of many massive clouds of gas and dust in our Milky Way galaxy, say contemporary astronomers, and is one of the largest. It is approximately 1,300 light years away from Earth. This enormous hazy cocoon, which measures approximately 30 to 40 light-years in diameter, is generating potentially a thousand stars.
