Question

a. State the type of motion exhibited by the bullet fired from a gun.
b. Define periodic motion.
c. The length of a table is measured to be 1745mm. How much is this length in meters?​

Answer 1

Answer:

(a) spin motion . A rapid lateral spinning motion, as it moves forward. This is due to the spiral grooves (Rifling) inside the gun barrel, which gives the bullet the spin. The spin ensures the bullet moves forward pointedly and sharply to its target, because otherwise it can tumble forwards!

(b) Any motion of a system that is continuously and identically repeated. The time T that it takes to complete one cycle of an oscillation or wave motion is called the period, which is the reciprocal of the frequency.

(c) 1.745 metres.

So,length (in metres)=(1745/1000)

=1.745.

Answer 2

Answer:

2  Any motion of a system that is continuously and identically repeated. The time T that it takes to complete one cycle of an oscillation or wave motion is called the period, which is the reciprocal of the frequency. See pendulum; simple harmonic motion. From: periodic motion in A Dictionary of Physics »

Explanation: 3 :1.745 metres. So,length (in metres)=(1745/1000)=1.745.
