They will attract each other when brought close but when they touch the glass rod will become a negative charge and will repel each other
Answer:
C. number of particles
Explanation:
Entropy is the measure of disorderliness of a system. Remember that when you dissolve salt in water, you increase the number of particles in the solution. The greater the number of particles in solution, the greater the entropy of the solution system.
Hence dissolution of a salt in water increases the entropy by increasing the number of particles in solution leading to the inequality; Ssolution > Swater + Ssalt.
Since they both have the same momentum, the object with the larger mass has a small velocity. (Remember that mass and velocity are inversely proportional with
p=mv.) Therefore, the smaller object will have the larger KE. (KE = 1/2 ^2)
Answer:
No.
Explanation:
The average distance to the center is over 6300km.
Use a sieve to separate the water from the iron fillings and sand.
Use a magnet to separate the iron from the sand.
