Whenever a conductor or a part of the conductor is moved in a magnetic field such that it is cutting the magnetic field lines or placed in a changing magnetic field the free electrons in the bulk of the metal start circulating in closed paths equivalent to current loops.
These loop currents resembles eddies in a fluid stream & hence called eddy currrent or foucault current.
Mass of any body is the quantity of matter contained in a given volume of the body. As we will go from one planet to another planet, the mass of a body i.e the content inside the body remains same. Hence the mass will remain constant. However as we have gone to the other planet ,so there…
Elastic collision : A collision in which both the momentum and kinetic energy of the body remains conserved. e.g. the collision between two metal balls. The basic characteristics of an elastic collision are ♦️Momentum is conserved.♦️Total energy is conserved.♦️Kinetic energy is conserved.♦️Forces involved in the interaction are of conservative nature.♦️Mechanical energy is not transformed into…
We can list the given data as, frequency n = 170Hz wavelength λ = 2m To find speed v = ? Solution – velocity , frequency and wavelength is connected by the formula v = n x λ v = 170 x 2 v = 340 m/s The speed of sound is 340m/s
Going through the sums, we can list the given quantities as, speed v= 1500 m/s time in which the signal is recieved back after hitting the shoal, i.e time for going+time for coming back i.e 2t = 0.45 s therefore t = 0.225s To find distance d = ? Solution – velocity, distance and time can be…
The given that can be listed is frequency n = 500Hz speed v = 350m/s we can find wavelength λ λ = v/n = 350/500 = 0.7m and time period T as T = 1/n = 1/500 = 0.002s = 2ms a) for a time difference of 1.0ms, phase difference ∆Φ = ? for a phase…
After going through the question, we can list the data as velocity v= 340m/s wavelength λ = 1.7m To find a) frequency n = ? b) period T = ? Solution – velocity can be written as v = n x λ n = v / λ n = 340…
