Answer:

0.037 volts

Explanation:

The formula for calculating the Electromagnetic field induction in a moving wire is:

Emf=B*l*v*sin(\theta )

Where:

B is the strength of the magnetic field in Webers or \frac{N*m}{A}

l is the longitude of the wire in meters

v is the speed of the wire crossing the magnetic field in meters per second (m/s)

and \theta is the angle between the magnetic field and the wire

So, substituting the values into the formula:

Emf = 3.96 * 10^{-3} W * 1.5 m * 6.2 \frac{m}{s} * sin(90)

sin(90)=1 so:

Emf = 3.96 * 10^{-3} W * 1.5 m * 6.2 \frac{m}{s} = 0.0368 volts ≅ 0.037 volts

A man is standing on the shore of a beach, up to his knees in water. Every second two waves hit him. What is the frequency of th
laila [671]

Answer:

f = 2 Hz

Explanation:

The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:

f = \frac{n}{t}

where,

f = frequency of the wave = ?

t = time passed = 1 s

n = no. of waves passing in time t = 2

Therefore,

f = \frac{2}{1\ s}

<u>f = 2 Hz</u>

A kite is 100m above the ground. if there are 200m of string out what is the angle between the string and the horizontal? (assum
jeka57 [31]

Answer :  The angle between the string and the horizontal is 30 degrees

Explanation:  Imagine this a a triangle where the length of the string (200m) is the hypotenuse and the height of the kite is the opposite side (100m) .

Let the angle between the string and the horizontal be theta.

Now  sin (Theta) = opposite side/hypotenuse

                             =  100/200 = 1/2

Therefore Theta = Sin ⁻¹ ( 1/2 )

Theta = 30 degrees

A small compass is placed near a very large piece of ferromagnetic material. Before the compass is placed near the material, it
NeTakaya

Answer:

it will move towards the object's magnetic south

Explanation:

The compass pints towards the earth geographic north because the magnetic south of the earth's magnetic field is located in there, if you placed such compass neaar the piece of ferromagnetic material, the magnetic field produced by the magnet will make the compass needle point towards its south magnetic pole, in the same fashion as it points to the earth's magnetic south. It will point to the object's south pole because the magnetic field will be stronger than the earth's (which is weak) that is because of the way magnetism works, opposite poles are attracted and similar poles will tend to separate from each other
