Intensity is proportional to the width of the slit. So, amplitude is proportional to the square root of the width of the slit. Here represent the widths of the two slits. ..

Introduction - The goal of physics is to provide an understanding of nature. The science of physics was developed to explain our physical environment. Great Physicists like Galileo, Newton, and Einstein etc. framed laws to explain the various phenomena in nature. These..

Let m be the mass of a body on Earth. Its weight on Earth is given by the equation The weight of the same body on moon (W m ) is given by, Dividing eq(2) by eq(1) we get, But we know that M e =100 M m and R e = 4 R m..

From equations (1) and (2) The first equation of motion is v = u + at. Substituting the value of v in equation (3) we get ..

01. A body of mass 2kg is raised to a height of 25m. Calculate the potential energy possessed by the body. Solution: Mass of the body (m) = 2kg Height (h) = 25 m Potential energy of the body = mgh 02. A bag of rice weighs 75kg. To what height is it raised if the work done in lifting it is 4900 J. S..

Let AB represent an object placed at right angles to the principal axis at a distance greater than the focal length f of the convex lens. The image A 1 B 1 is formed between O and F 1 on the same side as the object is kept and the image is erect and virtual. OF 1 = Focal length = f OA = Object dist..

Let a body of mass m be at a distance r from a body of mass M. The gravitational potential energy of the mass m is defined as the work done in bringing it from infinity to that point. The work done in moving the mass m through a small distance dr in the gravitational field of M is, dw = F dr The to..

Let m be the mass of a body in an orbit of radius r, velocity v and angular velocity ' w '. the centripetal force If T is the time period then, According to Kepler's third law, ..

It is the time taken by a satellite to complete one revolution around the Earth. Circumference of a circle of radius R + h is 2 p (R+h). Let T be the time period, v the velocity and h the height of the satellite above the Earth's surface. Substituting in the equation, we get ..
