Answer:
c)The gases have the same average kinetic energy.
Explanation:
As we know that the kinetic energy of gas is given as
here we know that
so we have
now we have
now mean kinetic energy per molecule is given as
so this is independent of the mass of the gas
so average kinetic energy will remain same for both the gas molecules
The diesel engine has no ignition system. (C)
It depends on the compression of the fuel/air mixture to ignite the mixture.
This may be a big part of the reason that Diesel engines always
sound to me as if they are falling apart.
Answer: • Visible Light, Radio Waves
• Radio - 305-m , at Arecibo, Puerto Rico
Visible Light - 10.4m Mirror, Canary Island
Explanation:
The spectral window is simply the range of frequencies that are correctly measured. It should be noted that the signals that are outside the spectral window are folded when they show up in spectrum.
The two spectral windows through which electromagnetic radiation easily reaches the surface of earth are the visible light and the radio waves.
Answer:
North
Explanation:
In an electromagnetic wave, the direction of the wave, the direction of the electric field and the direction of the magnetic field are all perpendicular to each other.
Therefore, we can find the direction of the magnetic field by using the right hand rule. We have:
- Index finger: direction of motion of the wave --> toward the center of Earth
- middle finger: direction of the electric field --> west
- thumb: direction of the magnetic field --> north
So, the magnetic field points north.
Answer:
<h3>The mass of an object is the same on Earth, in orbit, or on the surface of the Moon. ... 1N=1kg ⋅m/s2. 1 N = 1 kg · m/s 2 . ... The gravitational force on a mass is its weight. ... </h3>
