Apendulum is made of a small sphere of mass 0.250 kg attached to a lightweight string 1.20 m in length. as the pendulum swings back and forth, the maximum angle that the string makes with the vertical is 34.0∘. friction can be ignored. at the low point of the sphere's trajectory, what is the kinetic energy of the sphere

v=2 m/s

Explanation:

Given

Length of string L=1.2 m

mass of pendulum m=0.25 kg

maximum inclination with vertical \theta =34

vertical Rise of Pendulum from its mean position  is given by

Conserving Energy at top and bottom point

Potential Energy of sphere is converted into kinetic energy of sphere

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

snell's law

refractve index = sin incidence / sin refraction
