The difference between atoms and molecules is that atoms has a nucleus that is surrounded by electrons and Molecules are atoms bonded together by single, double or triple the bond.
the motion of the star
the temperature of the atmosphere of the star
all of the above
Answer:
all of the above
Explanation:
The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.
b. potential energy
c. radiant energy
d. thermal energy
B) a small rock sitting on top of a big rock
C) a stretched rubber band
D) a stone lying on the ground
a ball rolling on the ground
Answer:
b. Decreases
Explanation:
The total resistance of a series circuit is equal to the sum of the individual resistances:
(1)
Therefore, as we add more lamps, the total resistance increases (because we add more positive tems in the sum in eq.(1).
The current in a circuit is given by Ohm's law:
where V is the voltage provided by the power source and is the total resistance. We notice that the current, I, is inversely proportional to the total resistance: therefore, when more lamps are added to the series circuit, the total resistance increases, and therefore the current in the circuit decreases.
Answer: 43 minutes and 14 seconds.
Explanation:
The speed of light in a vacuum is approximately 186,282 miles per second (299,792 kilometers per second). To find the time it takes for light to travel from the Sun to Jupiter, divide the distance by the speed of light:
Time = (Distance from Sun to Jupiter) / (Speed of Light)
Time = (5.2 AU * 93 million miles/AU) / (186,282 miles/second)
Now, you can calculate the time in seconds and convert it to minutes:
Time = [(5.2 * 93 million miles) / (186,282 miles/second)] * (1 minute / 60 seconds)
Time ≈ [(483.6 million miles) / (186,282 miles/second)] * (1 minute / 60 seconds)
Time ≈ (2594.16 seconds) * (1 minute / 60 seconds)
Time ≈ 43.236 minutes
So, it takes approximately 43.236 minutes for light from the Sun to reach Jupiter, which is about 43 minutes and 14 seconds.
