Answer: 43 degrees
Explanation:
The force of the crutch can be broken into components. The horizontal component of F is the static friction force keeping the crutch from sliding. The vertical component is opposing the weight and is the Normal force. Using the orientation of the angle q, we have the following
fs = Fx = F sin (angle (tita))
N = Fy = F cos (angle(tita))
Maximum angle implies maximum static friction
Therefore,
fsmax = UsN = Us x F cos(angle tita)
Where U = miyu
F sin(angle tita) = Us x Fcos (angle tita)
Sin (angle tita) / cos (angle tita) = Us
Therefore, tan (angle tita) = Us
Angle tita = tan^-1(Us) = tan^-1 (0.931) = 42.95 degrees = 43 degrees
There for Angle tita Max = 43 degrees
Answer:
C the particle must be somewhere.
Explanation:
This is because normalization of wave function means the maximum probability of finding a particle in a region is 1. And a Wave function describes the probability of finding a particle in region. Also Since it is a probability distribution, its integral over all space must be 1, explaining that the probability that the particle is somewhere and thus it must integrate to 1, meaning it must be it must be normalizable
