I think it’s c but check cause I’m not sure
Astronomers use the color of stars to determine how hot they are and their brightness to estimate how far away they are. <em>(D)</em>
Answer:
Potential difference will be 151.9 volt
Explanation:
We have given capacitance of the capacitor
Voltage V = 49 Volt
Dielectric constant K = 3.1
We have to find the potential difference
We know that when a dielectric medium is introduced then p[otential difference is increases by k times
As the dielectric constant k = 3.1
So potential difference will be = 3.1×49 = 151.9 volt
The answer is B. P waves.
I took the test and it was correct. I hope this helps!
The closer the particles, the more will be the propogation of sound waves. Room contains air molecules which are far away from each other. So it takes much time for one molecule of air to disturb the other one. But in case of solids, as particles are much closer(compared to fluids), disturbance generated by one molecule is quickly transmitted to the next molecule
