Answer:
Δ S = -50 J
Explanation:
given,
Temperature, T = 500 K
Heat dissipates, Q = 25.0 kJ
Q = 25000 J
change in entropy, ΔS = ?
using equation of entropy
Δ S = -50 J
negative sign is used because heat is lost in the surrounding.
Hence, Change in entropy is equal to -50 J

Given :
Potential ,
Uniform magnetic field , B = 0.02 T .
Mass of proton , .
Charge on proton , .
Also , velocity of proton is perpendicular to magnetic field .
To Find :
The radius of the proton's resulting orbit .
Solution :
Now , when velocity is perpendicular to magnetic field radius of orbit is given by :
Putting all given values above :
Therefore , radius of orbit is 183.33 m .
Hence , this is the required solution .
Answer:If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.

Answer:
What is a Pure Substance?
Explanation:
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically).
