Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
An object is thrown at 25 m/s at 39 degrees above the horizontal from a 40m tall cliff. How long is it in the air?
INSTANTANEOUS VELOCITY: The velocity of a body at a certain instant of time is known as instantaneous velocity.
In a Newton's ring set up, the gap between the glass plate and the lens is filled with a transparent liquid. If the liquid is replaced by a second liquid, the rings shrink. Which o
Tesla; T (after N. Tesla, 1870-1943): The derived SI unit of magnetic flux density, described the magnetic flux density of magnetic flux of 1 Wb by an area of 1 m 2 ; thus it
Explain about the number of modes in the optical fibres. Mode in the optical fibres: A mode is a path occupied by a ray of light through an optical fibre. This is a mathemat
A universal column of 6m carries a Point Load of (180+n2) kN centrally at its axis. The column also carries one end of a simply supported beam of 5m with a uniformly distributed lo
A satellite of mass "M" is in orbit around the earth. If a second satellite of mass "2M" is to be placed in the same orbit, the second satellite must have a velocity which is:
FORCE ON THE PARTICLE: For a mass m to have acceleration, a force given by F = ma is always required. In uniform circular motion, acceleration is of value v2/t and is directed tend
what are advantages and disadvantages for the six''s thermometer
At what angle should a body be projected with a given velocity 24m/s just to pass over the obstacle 14m high at a given distance of 24m. Solution: 14=24xtan(θ)-(g*)(24 2
