What is the speed of a wave with a wavelength of 10 mm and a frequency of 5.0 Hz?

sleet_krkn [62]

Speed = wavelength × frequency
speed = 10/1000 × 5.0
speed = 0.001 × 5.0
speed = 0.005m/s

Suppose a straight wire with a length of 2.0 m runs perpendicular to a magnetic field with a magnitude of 38 T. What current wou

iragen [17]

Answer:

9.67 A

Explanation:

The weight of a student with a mass of m = 75 kg is:

$W=mg=(75 kg)(9.8 m/s^2)=735 N$

where g=9.8 m/s^2 is the acceleration due to gravity.

We want the magnetic force on the wire to be equal to this weight. The magnetic force on the wire is

$F=ILB sin \theta$

where

I is the current in the wire

L = 2.0 m is the length of the wire

B = 38 T is the magnetic field

$\theta=90^{\circ}$ is the angle between the direction of B and L

Since we want W=F, we can write

$ILB sin \theta=W$

And we can solve it to find the current I:

$I=\frac{W}{BLsin\theta}=\frac{735 N}{(38 T)(2.0 m)(sin 90^{\circ})}=9.67 A$
