A big dumb-bell is prepared by using a uniform rod of mass 60 g and length 20 cm. Two identical solid thermocol spheres of mass 25 g and radius 10 cm each are at the two ends of the rod. Calculate moment of inertia of the dumb bell when rotated about an axis passing through its centre and perpendicular to the length.
As per the given condition we can list out the data as mass of rod = M= 60g length of…
How much work is required to form a bubble of 2 cm radius from the soap solution having surface tension 0.07 N/m.
After going through the question, we observe some data as , initial radius = 0cm fina…

Two cars A and B, are moving along a straight road in the same direction with velocities of 25 km/hr and 40km/hr respectively. What is the velocity of car B relative to car A?
Given data in this problem can be listed as, velocity of car A = 25km/hr v…
The fastest server in the women’s game is Venus Williams of the United States of America, who recorded a serve of 205 km/hr during a match in Switzerland in 1998. Calculate the ball’s momentum if it has a mass of 58 g.
Given data here are, velocity , v= 205 km/ hr = 205 x 1000/ 3600 m/s v =…
