A long string carries the wave; a segment of the string measuring 6.00 meters in length and weighing 180 grams contains four full wavelengths. The string vibrates sinusoidally at a 50.0 Hz frequency with a 15.0 cm peak-to-valley displacement. The vertical distance between the farthest positive and negative positions is known as the "peak-to-valley" distance. The function that describes this wave traveling in the positive x direction is
.

If phase constant is
then
equation is ![$y=7.5 \times 10^{-2} \sin \left[100 \pi t-\frac{4 \pi}{3} x+\phi\right]$](https://tex.z-dn.net/?f=%24y%3D7.5%20%5Ctimes%2010%5E%7B-2%7D%20%5Csin%20%5Cleft%5B100%20%5Cpi%20t-%5Cfrac%7B4%20%5Cpi%7D%7B3%7D%20x%2B%5Cphi%5Cright%5D%24)
∴ equation is 
- A wave is a disturbance that moves from one location to another, carrying energy but not always matter.
- The square of the equation provides a probability density map of the locations where an electron has a specific statistical likelihood to be at any given moment in time. Wave functions have no direct physical meaning.

38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
Answer:
8 (maybe 18)
Explanation:
Depends on whether you have the d orbitals. If not, it's 8, and it's 18 including the d orbitals
Answer:
a) No, Two vectors with different magnitudes can never add up to zero.
b) Yes, Three or more vectors with different magnitudes can add up to zero.
Explanation:
a) No, Two vectors with different magnitudes can never add up to zero.
Given vector A and B
A = (x1,y1,z1) and B = (x2,y2,z2)
For A + B = 0
This conditions must be satisfied.
x1 + x2 = 0
y1 + y2 = 0
z1 + z2 = 0
Therefore, for those conditions to be meet the magnitude of A must be equal to that of B.
b) Yes, Three or more vectors with different magnitudes can add up to zero.
For example, three forces acting at equilibrium like supporting the weight of a person with two different ropes.
W = T1 + T2
Where;
W = Weight
T1 = tension of wire 1
T2 = tension of wire 2
