Answer: 15.29
Explanation: there you go have a nice day (*^p^*)
The momentul of the system preserves:
Ok, we found the speed after the collision.
Now, because the impact is plastic, it produces heat, sound energy and who knows what other forms of energy. We denote all this wasted energy with
.
Now, we write the energy conservation law:
From the above equation, you find
, and then conclude that the sound energy can certainly not be greater than this.
Answer:
Explanation:
The velocity of the vehicle would increase because the the tanks (when filled with water) must have exerted a force which would reduce the velocity of the vehicle at a certain pressure on the gas pedal. Note that force equals mass multiplied by acceleration; as the mass decreases, so the force decreases. Thus, when the mass exerted by this tanks (on the vehicle) decrease as a result of the hole punctured in them, the force exerted by the tanks would also decrease causing an increase in velocity of the pick up truck when the same pressure is applied on the gas pedal throughout (before and after the puncture).
The conservation law that applied here is the law of conservation of energy which states that energy can neither be created nor destroyed but can be transformed from one form to another. This is because the energy the vehicle used in carrying the load (the tanks) was transformed to the energy that resulted in increasing it's velocity (no new energy was formed as the pressure on the gas pedal remained the same).
Answer:
patron
Explanation:
The patron is something or someone who defends some cause or point of view. In the art field, for example, the patron may be considered a sponsor, that is, someone who is known for defending a particular group of people or specific situation.
The patron is one who advocates, advises and directs. In the military, patrons are heroic figures who are chosen to defend a military unit, for example.

Answer:
4 : 1
Explanation:
<h3><u>Pulse rate</u></h3>
Also referred as heart rate can be affected due to vigorous exercise, age, health. Normally the pulse rate of an adult is between 60 to 100 beats per minute. pulse rate: 80 bpm.
<h3><u>Breathing rate</u></h3>
The amount of oxygen taken in inside of our body from the air. Breathing rate is usually affected due to age. Normal breathing rate of an adult is between 15 to 24 breaths per minute. breathing rate: 20 bpm.
<h3><u>Ratio of breathing to pulse rate</u></h3>
pulse rate : breathing rate
80 : 20
4 : 1
