A student used a calorimeter to measure the amounts of energy released by equal samples of brown rice and carrots. The data from the experiment are shown below. Type of Temperature of Water Food Before Burning (°C) Temperature of Water Change in after Burning (°C) Temperature (°C) 25 43 18 Brown Rice Carrots 25 32 7 What conclusion can you draw from this experiment? O A. The two foods have the same amount of energy.
B. Brown rice has more energy than carrots.
C. Brown rice has less energy than carrots. D. The carrots released more heat when they burned.​

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
