A straight wire of length 0.74 m carries a conventional current of 0.6 amperes. What is the magnitude of the magnetic field made by the current at a location 3.3 cm from the wire?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
