Through what angle in degrees does a 33 rpm vinyl record turn in 0.23 s : a) 46° b) 26° c) 53° d) 33°

(a) angle record will be 46°

We have given speed = 33 rpm

Time t = 0.23 sec

We know that 1 revolution = 360°

So 33 revolution/minute

So angle record by vinyl , which is nearly equal to 46

So angle record by vinyl is 46°

So option (a) will be the correct answer
