Answer: fluorine
Explanation:
They are both halogens (group XVIII).
The maximum speed of the face is determined as 6.75 x 10⁻⁵ m/s.
<h3>
Maximum speed of the face</h3>
v = fλ
where;
- f is frequency of the wave
- λ is the wavelength
<h3>Angular speed of the wave</h3>
ω = 2πf
v(max) = ωA
v(max) = 2πfA
where;
- A is amplitude of the wave
v(max) = 2π(215)(50 x 10⁻⁹ m)
v(max) = 6.75 x 10⁻⁵ m/s
Thus, the maximum speed of the face is determined as 6.75 x 10⁻⁵ m/s.

Answer:
Explanation:
Shoveling gravel into the water will increase the buoyancy of the barge, which will make it float higher. Without data it is hard to tell if it will raise the barge enough to be counterproductive, but in any case throwing away the payload is not a good idea. Adding some weights would make the barge float lower, and then maybe the plie can make it under the bridge.
The water pressure is greatest at point B which has a larger diameter in this scenario.
<h3>What is Pressure?</h3>
This is defined as the force per unit area of a substance with its unit being Pascal.
The larger diameter will have more force acting on the sides which translates to a greater pressure.
