7) Se calcula dividiendo distancia entre tiempo

sveta [45]

Answer:

A) Rapidez

Explanation:

Speed is a scalar quantity and it is found by dividing the distance traveled by the time taken.

Speed = $\frac{distance}{time}$

Distance is the length of path covered whereas time is the duration of the travel.

Unlike velocity which is a vector, speed is a scalar quantity with only magnitude but no direction.

. A 2.0-m wire carries a current of 15 A directed along the positive x axis in a region where the magnetic field is uniform and

Lady bird [3.3K]

Answer:

The resulting magnetic force on the wire is -1.2kN

Explanation:

The magnetic force on a current carrying wire of length 'L' with current 'I' in a magnetic field B is

F = I (L*B)

Finding (L * B) , where L = (2, 0, 0)m , B = (30, -40, 0)

L x B = $\left[\begin{array}{ccc}i&j&k\\2&0&0\\30&-40&0\end{array}\right]$ = (0, 0, -80)

we can now solve

F = I (L x B) = I (-80)

F = -1200 kmN

F = -1200 kN * 10⁻³

F = -1.2kN
