Answer:

A simple machine consisting of an axle to which a wheel is fastened so that torque applied to the wheel winds a rope or chain onto the axle, yielding a mechanical advantage equal to the ratio of the diameter of the wheel to that of the axle.

A 0.210-kg metal rod carrying a current of 11.0 A glides on two horizontal rails 0.490 m apart. If the coefficient of kinetic fr

Answer:

The magnetic field is $B = 0.0764 \ T$

Explanation:

From the question we are told that

The mass of the metal is $m = 0.210 \ kg$

The current is $I = 11.0 \ A$

The distance between the rail(length of the rod ) is $d = 0.490 \ m$

The coefficient of kinetic friction is $\mu_k = 0.200$

Generally the magnetic force is mathematically represented as

$F_b = B * I * d$

Given that the rod is moving at a constant velocity, it

=> $F_b = F_k$

Where $F_k$ is the kinetic frictional force which is mathematically represented as

$F_k = \mu_k * m * g$

$B * I * d = \mu_k * m * g$

=> $B = \frac{\mu_k * m * g}{I * d }$

substituting values

=> $B = \frac{0.200 * 0.210 * 9.8 }{ 11 * 0.490 }$

=> $B = 0.0764 \ T$

melisa1 [442]

Answer:

True

Explanation:

The statement is true because According to Schrödinger it's not possible to get the exact position of where an electron is located. However, he showed from an equation that we can at determine the most likely area where an electron will be and he said they are most likely to be in the most dense area of the clouds.
