    A car moves in a circle at the constant speed of 50m/s and completes one revolution in 40s. Determine the magnitude of the acceleration of the car

    ByManoj Jaiswar October 3, 2025

    As per the given situation, v= 50m/s , T=40s , a= ? a = v x (2π / T )  a = 50 x (2 x 3.142 / 40 ) a = 50 x 0.1571 = 7.855 m/s²

    Assumptions Of An Ideal Gas

    ByManoj Jaiswar April 24, 2024June 14, 2025

    The following are the assumptions on which the kinetic theory of a gas is based on, 1. Gases are made up of large number of molecules. 2. The intermolecular distances are very large as compared to size of the molecules. 3. The gas molecules are constantly under random motion. 4. The collision between the two…

    As we go from one planet to another planet, how will the mass and weight of a body change?

    ByManoj Jaiswar November 23, 2023November 23, 2023

    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…

    A wave of frequency 500 Hz is travelling with a speed of 350 m/s. (a) What is the phase difference between two displacements at a certain point at times 1.0 ms apart? (b) what will be the smallest distance between two points which are 45º out of phase at an instant of time?

    ByManoj Jaiswar November 9, 2023November 9, 2023

    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…

    Elastic and inelastic collision and their characteristics

    ByManoj Jaiswar September 25, 2023November 9, 2023

    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…

    Distinguish between elasticity and plasticity

    ByManoj Jaiswar September 10, 2023November 9, 2023

    Elasticity If any body regains is original shape and size after removal of deforming force that property is called as elasticity The restoring forces that gets developed in the body are very strong and it is capable to bring the displaced molecules to their original positions, and hence helps the object in regaining the original…

    Stationary Wave On String

    ByManoj Jaiswar September 9, 2023November 9, 2023

    A string tied to both ends can form stationary wave on it. The current setup is of Melde’s Experiment in parallel position. Here on loop is shown with two node(N) and one antinode(A) at the middle. Also the distance between two node is shown in the picture

    What are Keplers Law for planetory motion

    ByManoj Jaiswar August 15, 2023November 9, 2023

    Kepler’s laws of planetary motion are three laws formulated by the German astronomer Johannes Kepler in the early 17th century. These laws describe the motion of planets around the Sun and have since played a crucial role in understanding the mechanics of the solar system. The three laws are: 1. The Law of Ellipses: Kepler’s…

    Side effects of excessive use of mobile phones

    ByManoj Jaiswar August 15, 2023November 9, 2023

    Excessive use of mobile phones can have several side effects on both physical and mental health. Some of the common side effects include: 1. Eye strain and vision problems: Staring at the screen for long periods can lead to eye strain, dry eyes, blurred vision, and even nearsightedness. 2. Sleeping problems: The blue light emitted…
