Answer:
kinetic
Explanation:
A vehicle takes good chemical energy stored in the bonds of hydrocarbons (gasoline) and converts it into movement (kinetic energy), air vibration (noise), and heat (wasted energy in the summer), some electricty for the radio, spark plugs, fans, and cell phone charger. But the aswer here is kinetic, since the word "moving" is specified.
True.
Density = mass / volume, Unit = g / cm³.
This is a common unit because of its affiliation with the SI unit and because that also our popular liquid which is water = 1 g/cm³
Hi Babylilith32,
Your Question:
An experiment was devised to investigate the effects on the temperature of a cup of coffee when cream is added at different time intervals. Hot and cold water were used instead of coffee and cream. First, a container of water heated to 80°C was allowed to sit for 15 minutes. Its temperature was measured at regular intervals. Next, similar temperature measurements were taken for 15 minutes on a new container of heated water, but this time some cold water was added after the 2-minute reading. Finally, the procedure was repeated except that for this last test, the cold water was added after the 12-minute reading. The resulting recorded temperatures were plotted on the graph shown here.
Answers:
1. If you have cool water then you have to add it to the hot water after a few minutes.
2. The independant variable is the cold water
3. The dependant variable is the temperature
4. The control is the hot water without the cold water.
5. The 2 min cold water drops way to much.
In 1920, after returning from Army service, he produced a successful model and in 1923 turned it over to the Northeast Electric Company of Rochester for development.
The size of the forces between you and the planet you're on is
your weight on that planet.
Don't forget that you pull the planet with a force equal to the force
that the planet pulls on you. Your weight on Earth is the same as
the Earth's weight on you !
