Answer:
B/4
Explanation:
The magnetic field strength is inversely proportional to the square of the distance from the current. At double the distance, the strength will be 1/2^2 = 1/4 of that at the original distance:
The field at twice the distance is B/4.
Answer:
57.1 km/hr
Explanation:
To find the average speed you take the total distance divided by the total elapsed time.
So, the total distance is 140 + 60 = 200
the total elapsed time is found by taking 140/70=2 and 60/40=1.5
2+1.5=3.5
The plug the numbers into the equation,
200/3.5=57.1
Good offer but I dont know any of this sorry
Answer:
0.9N/C
Explanation:
-The force of a charged particle in an electric field is given by the equation;
#we substitute the values of the charge and field strength:
Hence, the electric force acting on the charge is 0.9N/C
