A Cadillac Escalade has a mass of 2 569.6 kg, if it accelerates at 4.65m/s2 what is the net force on the car?

How does a balanced equation show the conversation of mass

What is the specific heat capacity of a metal if it requires 177.5 J to change the temperatures of 15.0g of the metal from 25.00 degree celcius to 34 degree celcius

A laboratory experiment requires 250 millimeters of water for boiling. It also requires 100 millimeters of water for a cooling process.

1. A food sample is burned in a calorimeter that contains 2000. g of water. The temperature increases from 22.0°C to 44.3 °C. How many Calories does the food sample contain, assuming all of the energy from the food was transferred into the water?

Why doesn't water light on fire? It has all the ingredients except heat! Hydrogen for the flammability factor, oxygen so it can keep burning, and all you need to do is add heat and BOOM you have a flame! 15 pts
