Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/a due south 4.00s later. find (a) the x and y components of the coyote’s average acceleration during the time and (b) the magnitude and direction of the coyote’s average acceleration during that time

momentum of soft ball three times less than baskey ball

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
