To develop this problem we will apply the concepts related to energy conservation, in this way the change in kinetic energy must be equivalent to the change in potential energy. Finally we will obtain a speed dependent expression to find the maximum height that can be reached for the two given angles, given that the first cannon ball is fired with a speed of 1050m/s at angle of 35°.
Therefore the vertical velocity will be,
Use the law of conservation of energy to find the height
Replacing with our values,
Therefore the maximum height reached by the first ball is
The second cannon ball is fired at an angle of 90°. Hence, the maximum height reached by the second ball is,
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.
<h3>What is the Avogadro’s number?</h3>
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.
The scientist Josef Loschmidt strengthened the Avogadro’s number by obtaining the number of particles in one cubic centimeter of gas under standard conditions.

Answer: 0.081 kilogram/cubic meter
Explanation: p=m/v so 104/1278 is 0.081377151799687 or 0.081.
I'll put what is happening and I'll let you put it into your own words.
Point A is emitting a sound wave that travels down into the water and finds the ship (point B). The sound wave then bounces off the the ship and travels to a receiver that is located on the back of the ship (Point C). The ship then calculates the time from the emission of the wave to the reception of the wave and from there calculates the depth of the object.<span />
