A moving charged particle creates a magnetic field around it. Charge through a wire creates a magnetic field around it, the properties of which can be determined using a right hand rule.
All magnetic fields are created by moving charged particles. Stationary charged particles do not generate magnetic fields. An electromagnet is a magnet that relies on an electric current to produce the magnetic field.
i hope this really helps..
Omg. Ummm. I am pretty sure it is Shift toward the red end of the spectrum
<h2>The temperature of the air is 66.8° C</h2>
Explanation:
From the Newton's velocity of sound relationship , the velocity of sound is directly proportional to the square root of temperature .
In this case The velocity of sound = frequency x wavelength
= 798 x 0.48 = 383 m/sec
Suppose the temperature at this time = T K
Thus 383 ∝
I
The velocity of sound is 329 m/s at 273 K ( given )
Thus 329 ∝
II
Dividing I by II , we have
= 
or
= 1.25
and T = 339.8 K = 66.8° C
Answer:
The answer is definitely Water
This sounds like thermal expansion.
