Answer:
1 L = 1000 cm^3
1 m^3 = 1000 L = 10^6 cm^3
1 m^3 = 10^6 g = 10^3 kg density of water
M = Density * Volume
V = 2 * 4 * 5 = 40 m^3
M = 10^3 kg / m^3 * 40 m^3 = 4.0 * 10^4 kg
Answer:
First trial: Big ball dropped first, feather fell much later

happy to help ya:)
Answer:
B = 8.0487mT
Explanation:
To solve the exercise it is necessary to take into account the considerations of the Magnetic Force described by Faraday,
The magnetic force is given by the formula
Where,
B = Magnetic Field
I = Current
L = Length
Angle between the magnetic field and the velocity, for this case are perpendicular, then is 90 degrees
According to our data we have that
I = 16.4A
F = 0.132N/m
As we know our equation must be modificated to Force per length unit, that is
Replacing the values we have that
Solving for B,
Not sure what even is that
