Answer:
Magnetic field, B = 0.05 T
Explanation:
It is given that,
In magnetic force on a current carrying wire" experiment using the data for force (y-axis, in Newton) versus length in meters, someone obtained a linear curve fit count
y = 0.1 x + 2
Where,
x is in meters
and y is in newtons
Slope of the equation,
Magnetic force is given by,
So, the strength of the magnetic field is 0.05 T. Hence, this is the required solution.
Elaine can use a resistor in her circuit to reduce the rate of flow of charge(current), as a resistor resists the flow of charges, so it's amount would be reduced.
In short, Your Answer would be Option C) "A Resistor"
Hope this helps!
Answer:
0.0786
Explanation:
zero after the decimal place is not a significant figure since it comes before the real integer "7".
"5 " in ten thousandth place is rounded off to "6" because the next digit is also another "5",
so we get the three sfg 0.0786
