  1. The total mechanical energy of a satellite in a circular orbit is determined by its mass and the radius of its orbit. For satellites A and B, the ratio of their masses is 3:1, and the radii of their orbits are r and 4r , respectively. The mechanical energy of a satellite in orbit is directly proportRead more

    The total mechanical energy of a satellite in a circular orbit is determined by its mass and the radius of its orbit. For satellites A and B, the ratio of their masses is 3:1, and the radii of their orbits are r and 4r , respectively. The mechanical energy of a satellite in orbit is directly proportional to its mass and inversely proportional to the radius of the orbit.

    Satellite A, having three times the mass of satellite B, has a greater gravitational interaction, leading to higher energy. However, its energy is also inversely related to the smaller orbital radius \( r \). Satellite B, with one-third the mass of A, moves in a larger orbit with a radius 4r . which further reduces its total mechanical energy.

    Taking both the mass and orbital radius into account, the total mechanical energy of A is significantly larger than that of B. Specifically, the energy of A is 12 times that of B. This ratio arises because the increased mass of A amplifies its energy, while B’s larger orbital radius reduces its energy proportionally. Thus, the ratio of their total mechanical energies is 12:1, reflecting these combined effects.

    In Kho-Kho, the chain formation is a defensive strategy where chasers form a connected line, moving together to block defenders’ escape routes. Each chaser has a specific role, ensuring the team covers the entire field efficiently. This synchronized movement prevents defenders from crossing the central lane, making it easier to tag them. Proper chain execution requires coordination, anticipation, and awareness of defenders’ moves.
    Answer: (B) Chasers forming a connected barrier

  5. In Kho-Kho, two poles are positioned at opposite ends of the central lane. These poles play a crucial role in gameplay, allowing chasers to perform quick turns while maintaining speed and balance. Proper use of poles through pole turns and dives enhances game tactics, enabling chasers to cover moreRead more

    In Kho-Kho, two poles are positioned at opposite ends of the central lane. These poles play a crucial role in gameplay, allowing chasers to perform quick turns while maintaining speed and balance. Proper use of poles through pole turns and dives enhances game tactics, enabling chasers to cover more ground while chasing defenders efficiently.
