A simple pendulum completes 40 oscillations in one minute. Find its (a) frequency, (b) time period. Ans. (a) 0-67 s (b) 1-5 s 1.

Answer»

on b:1.5sExplanation:Number of Oscillations, N=40  TIME t=1min FREQUENCY f=  t /N  =  60/ 40 =0.667Hz  Time period,T=  1/f   =1.5sec Hence, frequency is 0.667Hz and time period is 1.5sec

A body is travelling along a circular path of radius 7m. While it reach diametrically opposite end in its first rotation .Find distance and displacement​

Answer»

Explanation:A body is moving along a circular path of radius r What will be the distance COVERED and the displacement of the body after HALF a revolution According to your QUESTION, the body moves from point A to point B thereby completing half a revolution. Since distance is the length of path covered THEREFORE it will be equal to half the circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distance between initial and final point.hope this ANSWER helps uh plz mark my answer as brainlist answer

lection of LIGHT rays is one of the major aspects of geometric optics; the other is refraction, or the bending of light rays. Geometric optics is one of two broad classes of optics, the field that "deals with the propagation of light through TRANSPARENT media," according to Richard Fitzpatrick, a professor of physics at the University of Texas at Austin, in lecture NOTES for a course in Electromagnetism and Optics. (The other CLASS is physical optics.)

In the circuit diagram shown, the two resistance wires A and B are of same length and same material, but A is thicker than B. Which ammeter will indicate higher reading for current? Give reason.

Answer»

resistance is inversely proportional to Area So in this CASE A is thicker and has more area compared to B hence A less lesser RESISTANCEAND V= IR so at CONSTANT V I is inversely proportional to R Hence A having LEAST resistance it has more current and higher ammeter READING Explanation:

Answer»

Final ANSWER: Minimum series Resistance : 5ohmSteps and Understanding:1) Maximum POTENTIAL difference across lamp is 60V.Internal Resistance of Lamp, r = 20ohm.Maximum CURRENT across it that will flow through out the. circuit,By Ohm, 's Law,I(max) = V(max) / r = 60/ 20 = 3A.2) SINCE, 60 V is across Lamp so remaining15 V will. be across External Resistor.Current, I(max) = 3A.Minimum Resistance, R = 15V/ 3 = 5ohm.This is resistance required to sufficient use of lamp at Max Volt 60 across lamp.hope it helps
