Assuming you're working in a 3D cartesian coordinate system, i.e. each point in space has an x, y, and z coordinate, you add up the forces' x/y/z components to find the resultant force.
B. it would become a liquid
hope this helps
Answer:
The correct answer is "4.26 m".
Explanation:
Given:
Wavelength,
or,
Distance,
or,
Distance between the 1st and 2nd dark fringes,
As we know,
⇒
or,
⇒
By substituting the values, we get
Answer:
0.7
Explanation:
Reasoning The distance between adjacent crests is the wavelength l. Since the speed of each wave is v = 3.00 × 108 m/s and the frequencies are known, the relation v = fl can be used to determine the wavelengths. The equation v = fl applies to any kind of periodic wave.
