Answer:
I don’t want to download a pdf that I don’t know what it is…
Also, brainly strictly says that we can’t post questions about a test or quiz that is found in school…
Explanation:
Answer:
Its the temperature at which the molecules of a matter especially a liquid attain higher kinetic energy and the rate of collision becomes increased
Explanation:
Answer: The correct statements are ; A and B.
Explanation:
The strength of the magnetic field(B) in an electromagnet can be calculated using formula:

= Relative permeability
N = number of turns
I = Current in the wire of the solenoid
L = length of the solenoid or electromagnetic
As we can see from the formula:


So, by increasing the turns and increasing current flowing through wire one can increase the strength of an electromagnet.
Hence, the correct statements are ; A and B.
b) law of conservation of energy
Answer:
is an example of precipitation from a solution.
