An unfortunate bug splatters against the windshield of a moving car. Compared to the deceleration of the car, the deceleration of the bug is .

Larger

Explanation:

We experience most blug spat during the night, even flies and this is because they usually flow with light of the headlight of the car, they use to fly up with some feet so making them to fall on windscreen.

So ,Comparing the deceleration of the car, the deceleration of the bug is larger as the car is moving.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

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.
