To find or discover by investigation?
<span>The last main subatomic particle to be discovered was the
antihelium-4. It was discovered on 2011
and it is measured and produces through the STAR detector. The Antihelium-4 was discovered accidentally
when an experiment was conducted. It is
also the first particle that was discovered by the means of experiment.</span>
Answer:
Explanation:
Given that,
The current in the loop, I = 2 A
The radius of the loop, r = 0.4 m
We need to find the magnetic field at a distance 0.09 m along the axis and above the center of the loop. The formula for the magnetic field at some distance is given as follows :
Put all the values,
So, the required magnetic field is equal to .
Answer is 1500 m/s
Wave speed = Frequency x wavelength
500.0 x 3.00 = 1500 m/s
Answer:
p = mv (mass x velocity)
p = 15kg x 10 m/s = 150 kg-m/s
so your answer is C.
