Yes. All scales must be zeroed out. It's hard to tell how it affects the results.
Absolute zero ,-273 degrees centigrade approximately
The idea is to start at absolute zero - the lowest possible temperature. This happens to be -273.16 on the Centigrade (Celsius) scale. The Kelvin scale has no negative temperatures; zero degrees Kelvin is the lowest possible temperature.
It is due to the charging and discharging of capacitor in the circuit....
Yes it is. It has to do with static vs. kinetic friction. You can test this with a fish-scale and some type of object to pull across the floor/table. The initial "weight" reading on the scale will be higher when you start trying to move the object than the reading during movement. I'm sure you could find a youtube video to demonstrate this for you.
If you hold a thermometer close to you it will start to heat up. Your body temperature will start affecting it and the heat reading on it should start to rise. Once you pull it away from you (depending on the temperate of where you are) it should start to cool off again.
a mistake (aka faliure start again)
Most people would say to start over again.
It is impossible to tell how long from the start of the experiment it was before all of the substance turned into a liquid without more information about the experiment. Perform the experiment again and use a timer to determine the length of time required to turn the substance into a liquid through heating.
It is simply the scientific method in action. Make a mistake, correct it and go on or start again.
They need to keep a record of each step, then start the experiment over and try not to make the mistake again or make changes in what they did to see what outcome they get.
forgot
You can start a large scale industry if you have adequate financial outlay.
You can go to the manger of the store and explain to them that you have forgotten and see if there is any way that you could start paying again without opening a new account
Any experiment should start with a hypothesis.
Worst of all, I forgot my homework in my locker.
An experiment is the thing that you perform, and a hypothesis is the guess you make at the start (before the experiment) to determin what's going to happen.
It is the temperature at the start of the experiment.
