The corect answer would be C.
Explanation:
The flow rate set at a differentt time would be the correct measurement beecause wats and speed add up to your main answer.
Answer:
The law of floatation is applied in all vessels which travel by waterways that include ships, submarines and ferry boats. It is also applied in some vessels which travel by air ways such as hot air balloon and air ship. Balloons of different colors and shapes are filled with lighter gas so that will float in air.

Answer: The structure for the boron nitride molecule will be linear.
Explanation: When boron and nitrogen combine together to form a compound, the boron element will loose 3 electrons which will be easily accepted by the nitrogen element.
Boron : Atomic number is 5
Electronic configuration:
To attain stable configuration, boron will loose 3 electrons easily.
Nitrogen : Atomic number is 7
Electronic configuration:
To attain stable configuration. nitrogen will gain 3 electrons easily.
Hence, to form a molecule with these two elements, there will be 3 bonds present in between them and 1 pair of lone pair will be left on the nitrogen atom.
Structure of boron nitride ( which is linear) is attached in the image below.
Answer:
As balloons rise, air pressure around them diminishes. When the ballon is made of elastic material, it expands because of the excess pressure inside. Its volume increases and its internal pressure decreases
Explanation:
