The magnetic field is strong near the ____ of a magnet.
shtirl [24]

The magnetic fields of magnets are most powerful at the <u>poles of a magnet</u>. Without any difference in the magnitude, both the poles have equal amount of Magnetic field intensity at their poles.

If you see the field lines we can see the field lines start from the North Pole run parallel and end at the South Pole.  The field lines are concentrated more at the poles hence the magnetic field intensity or the magnetic field itself is more at the poles than any other part.

A stationary horn emits a sound with a frequency of 228 Hz. A car is moving toward the horn on a straight road with constant spe
stiks02 [169]

Answer: 26.84 m/s

Explanation:

Given

Original frequency of the horn f_o=228\ Hz

Apparent frequency f'=246\ Hz

Speed of sound is V=340\ m/s

Doppler frequency is

\Rightarrow f'=f_o\left(\dfrac{v+v_o}{v-v_s}\right)

Where,

v_o=\text{Velocity of the observer}\\v_s=\text{Velocity of the source}

Insert values

\Rightarrow 246=228\left[\dfrac{340+v_o}{340-0}\right]\\\\\Rightarrow 366.84=340+v_o\\\Rightarrow v_o=26.8\ m/s

Thus, the speed of the car is 26.84\ m/s
