Answer:
about 4 km
Explanation:
15 minutes is a quarter of an hour, so you divide 16km by 4 to get your answer
Answer:
discrete lines are observed by the spectroscope, the emission of the lamp is of the ATOMIC source
Explanation:
Bulbs can emit light in several ways:
* When the emission is carried out by the heating of its filament, the bulb is called incandescent, in general its spectrum is similar to that of a black body, this is a continuous spectrum with a maximum dependent on the fourth power of the temperature of the filament.
* The emission can be by atomic transitions, in this case there is a discrete spectrum formed by the spectral lines of the material that forms the gas of the lamp, in general for the yellow emission the most used materials are mercury and sodium or a mixture of they.
Consequently, as discrete lines are observed by the spectroscope, the emission of the lamp is of the ATOMIC type
Answer:
The value of resistance when power is 1100 watts =
= 50 ohms
Explanation:
Power
= 2200 Watts
Resistance
= 25 ohms
Power
= 1100 Watts
Resistance
= we have to calculate
Given that the power in an electric circuit varies inversely with the resistance
⇒ P ∝ ![\frac{1}{R}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR%7D)
⇒
= ![\frac{R_{1} }{R_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BR_%7B1%7D%20%7D%7BR_%7B2%7D%20%7D)
⇒
= ![\frac{25}{R_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7BR_%7B2%7D%20%7D)
⇒
= 50 ohms
This is the value of resistance when power is 1100 watts.
Answer:
i really thought that said hater
The major difference is: Mercury has no orbiting satellites, while Jupiter has many satellites that surround it, so the correct answer is C
