The largest possible displacement on a circular track is the straight-line distance between the starting point and the point directly opposite it, half-way around the circle. That's the diameter of the track ... 204 meters.
Applying the ideal gas equation:
PV = nRT
PV = (mass/Mr)RT
mass = PVMr/RT
mass = (101325 x 4672.2 x 4) / (8.314 x 297)
= 766887.3 kg
= 7.7 x 10⁵ kg
Answer:
steam will have the lowest density.
Hope it will help :)
Answer:
.25 Hz
Explanation:
Period = 4 sec
freq = 1/p = 1/4 hz = .25 Hz
<h2>
Answer: 2 lights (in parallel)</h2>
Explanation:
When light bulbs are connected in series the total voltage
will be:
(1)
This means the <u>total voltage will be distributed among each of the bulbs</u> in series, therefore the luminosity will be also divided among the bulbs.
When lights are connected in parallel the total voltage
will be:
(2)
This means the <u>total voltage will be the same for each bulbs</u> in parallel, therefore the luminosity will be the same.
Now, if we combine this two types of connections, as in this problem with 11 lights in series, which are also in series with 2 lights in parallel; the 2 lights in parallel will be brighter than the 11 lights in series.
