Can someone do this fun experiment for me!? Materials:
-Hot Water
-Cold Water
-Foam Cups
-Thermometer
-Measuring Cup
kk, then:
-Gather materials.
-Measure 50 ml of hot water and 50 ml of cold water into separate foam cups.
-Use a thermometer to measure the temperature of hot water and the cold water.
-Pour the hot and cold water into a third foam cup.
-Allow some time for the thermometer to reach a final temperature, then measure the temperature of the water.

kk, after your done please record your temperatures, and that's all! enjoy your 43 points!!

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

(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
