Answer and Explanation:
DE BROGLIE 'S HYPOTHESIS :
- According to De broglie the matter have dual nature it can behave as particle as well as wave
- According to this hypothesis all matter have wave like property and having wavelength.
- The de broglie wavelength is given by
here h is plank's constant and P is momentum - This hypothesis determines the probability of finding the object at a give point
Answer:
Explanation:
angular acceleration α = 5 rad /s ²
θ = 1/2 α t² , θ is angle of rotation , t is time .
= .5 x 5 x 4²
= 40 rad .
θ = l / r , θ is angle formed , l is length unwound , r is radius o wheel .
l = θ x r
= 40 x .1
= 4 m .
In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.
Answer:
Explanation:
The <u>initial</u> vertical velocity is 540sin55° = 442.342103... 442 m/s
The <u>initial</u> horizontal velocity is 540cos55° = 309.731275... 310 m/s
In the real world, both initial velocities would be reduced by air resistance and vertical velocity will be altered by gravity.
