A conducting rod (length = 2.0 m) spins at a constant rate of 2.0 revolutions per second about an axis that is perpendicular to
vladimir2022 [97]

Answer:

0.050V

Explanation:

To solve this problem it is necessary to use the concepts related to the potential between two objects that have a magnetic field, this concept is represented in the equation.

\int dV = \int_{0}^{l/2} Bv (dl)

Where,

v= tangencial velocity

B = Magnetic Field

We know for definition that,

v= l\omega

Where,

L = length

\omega = Angular velocity

We can replace this values in our first equation then,

\int dV = \int_{0}^{l/2} B (l\omega) (dl)

Integrating we have,

V = \frac{1}{8} Bl^2 \omega

Replacing the values,

V= \frac{1}{8} (8*10^{-3})(12.56)(4)

V = 0.050V

Therefore the potential difference between the  center of the rod and the other rod is 0.050V

Mama L [17]

Answer:

The answer is "In this information, Enzo will be confident that if any fertilizer is required only for plants".

Explanation:

The Beans plants were members of the group of legumes. Legume flowering plant under which the roots form nodules. These nodules require a specific bacterium called bacteria, which fix nitrogen. Its bacterium transforms nitrogen from the atmosphere into the soil's nitrate. Consequently, for some of its growth, beans do not require fertilizer.
