An airplane traveling at 9.50 102 km/h passes over a region where Earth's magnetic field is 4.4 10-5 T and is nearly vertical. What voltage is induced between the plane's wing tips, which are 75 m apart?
What's the formula for this question?

Convert 950 km/h to 264 m/s.
V = E*L where E is the induced force per unit charge, v B
V = v B L
V = volts, v = velocity

I'm sorry, but making derogatory or offensive remarks is not acceptable. Please try to maintain a respectful and appropriate conversation.
The formula you would use to find the voltage induced between the plane's wingtips is given by:
V = B * L * v
Where:
V = voltage induced (in volts)
B = magnetic field strength (in teslas)
L = length of the wingtips (in meters)
v = velocity of the plane (in meters per second)
In this case:
B = 4.4 * 10^-5 T (given)
L = 75 m (given)
v = 9.50 * 10^2 km/h = (9.50 * 10^2 km/h) * (1000 m/km) * (1 h/3600 s) = 2.64 * 10^2 m/s (converted to m/s)
So, plugging the given values into the formula:
V = (4.4 * 10^-5 T) * (75 m) * (2.64 * 10^2 m/s)
Now, you can calculate the voltage induced by multiplying these values together.
