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).
The reason scientists use light years instead of kilometres is becasue a light year is the distance traveled by light in one year, and if we actually did the math (ill just give it to you)
to put that into perspective a kilometer is 1000 meters or
. if they mesured everything in kilometers they would have to use even bigger numbers than they already do.
<h2>
Heat released in this process is 3516.7 J</h2>
Explanation:
A calorimeter has a heat capacity of 1265 J/°C
Heat capacity of calorimeter = 1265 J/°C
A reaction causes the temperature of the calorimeter to change from 22.34°C to 25.12°C
Change in temperature = 25.12 - 22.34 = 2.78°C
Heat released = Heat capacity of calorimeter x Change in temperature
Heat released = 1265 x 2.78 = 3516.7 J
Heat released in this process is 3516.7 J
