Example: calculate elasticity when p = 30 and qd= 400 –10p.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

thermal energy is the answer

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
