Answer:
the compass direction of the resultant displacement is
south of west
Explanation:
Generally using cosine we can obtain the resultant R as follows

=> 
=> 
We can obtain the direction of the resultant by first using sine rule to obtain angle C as follows

=> ![C= sin ^{-1} [\frac{A * (sin 70)}{R} ]](https://tex.z-dn.net/?f=C%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7BA%20%2A%20%20%28sin%2070%29%7D%7BR%7D%20%5D)
=> ![C = sin ^{-1} [\frac{20 * (sin 70)}{19.48} ]](https://tex.z-dn.net/?f=C%20%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7B20%20%2A%20%20%28sin%2070%29%7D%7B19.48%7D%20%5D)
=> 
Then the direction is obtained as

=> 
=> 
Hence the compass direction of the resultant displacement is
south of west
Answer:
1.241/s
Explanation:
From this question, we have the following information:
Mass of oscillator = 310
The time Period, t = 0.180
Decrease = 20 %
Amplitude of oscillation has the formula
A = Aoe^yt
1-20% = 80%
= 0.80
Y x 0.18 = -ln(0.8)
= 0.18Y = 0.2234
Y = 0.2233/0.18
Y = 1.241/s
The damping constant y is Therefore equal to 1.241s
Answer:


Explanation:
= Mass of first object
= Mass of second object
v = Speed of both objects
= Combined velocity
The ratio of final kinetic energy to initial kinetic energy will be

The ratio is 
As the linear momentum is conserved

Divide by
on both sides

The ratio of mass is 
I'm pretty sure the answer to this question is B. If the behavior is common in certain cultures
Their behavior wouldn't be wrong or considered a psychological problem if it's part of their culture.
