Answer:
configuration of string:
Node - Antinode - Node or N-A-N
This is 1/2 wavelength since a full wavelength is N-A-N-A-N
f (fundamental) = V / wavelength
F0 = 300 m/s / 1 m = 100 / sec
F1 = 300 m/s / .5 m = 600 / sec
Each increase is a multiple of the fundamental since the wavelength
increases by 1/2 wavelength to keep nodes at both ends of the string
A special purpose nozzles that are often lowered through holes or other openings to the cellar of an occupancy are called cellar nozzles.
What is a nozzle:
A nozzle is a device in which steadily flowing fluid can be made to accelerate by a pressure drop along the duct in a cross-sectional area.
So when a fluid flows through a nozzle, its velocity increases continuously and pressure decreases continuously.
There are different types of tips like hollow cone, solid cone or flat fan.
The cellar nozzle (also called a Bresnan nozzle) is designed to be used under the surface the operator is standing on.
Hence,
The cellar nozzles are often lowered through holes or other opening to the cellar of an occupancy.

The answer would be: <span>b. interactions between the atmosphere and geosphere during a drought
The experiment is clearly demonstrating what happens in drought. The soil that is put into direct sunlight without getting any water. The heat from the sunlight will be absorbed by the soil, makes the water content of the soil evaporates into the air. Since you don't give any water, the soil will be dry and start to crack.
The soil should represent the geosphere. The air represents the atmosphere.

The answer is that "elements are a single atom and compounds are a mixture of two elements or more." Elements are atoms that have protons, neutrons, and electrons. Compounds are mixtures with two or more elements.
Hope this helps.
Answer:
6logs
Explanation:f
First finding the volume of the logs
V= π/4d²l
= 0.098m³
So number of logs will be
Weight of 2 boys + weight of log = buoyancy force.
So
2( 400)+ N ( Mlog x g) = density of water x volume displaced x g
2(400) = N x 0.098x 1000x 9.8 x 0.9- 0.75* 1000
N= 5.5 which is approx 6logs
