The answer to your question is OPTION B
        
             
        
        
        
An example of conductors of heat would be iron pans. a example of electric insulators would be copper, gold and silver. to contrast conductors and insulators, insulators let electricity pass through them while conductors restricts electricity. both conductors and insulators can work with lithium and sodium.
        
             
        
        
        
The word "static" would be known to be friction as air rushing against an airplane
        
             
        
        
        
In question 1, both of your answers are correct, but I don't understand the process you went through in the 'a' part.
R = v/I . That's a correct formula.
But it doesn't help you in this form, because you need to find I 
So turn it into a helpful form ... Solve it for I, so it says I=something.
R= v/I
Multiply each side by I : R I = V.
Now divide each side by R: I= V/R .
THERE'S the equation you want.
I = V / R
I = 1.5 / 10 = 0.15 Amp.
That's slightly cleaner, although I don't really understand what you were actually thinking in that part.
But again ... You answered both parts correctly, and your process in b is fine.
        
             
        
        
        
Answer:
v =25 m/s
time= 50 s
Velocity =Displacement/Time
Displacement = Velocity × Time
S = 25×50
s=1250m
Explanation:
v =25 m/s
time= 50 s
Velocity =Displacement/Time
Displacement = Velocity × Time
