Read the book and figure it out yourself! Suspense people!
No, i dont think you lose 21 grams of weight when you die. a scientist made an experiment, attempting to figure it out. the very first time he tested it out, the weight of the persons was 21 grams diffrent. in later attempts, with other persons, it was not.
what you do is an experiment. get a bowl with 3 cups of normal water. then get another bowl with 3 cups of salt water. then get some items to test it with. after you tried an item clean it and dry it. do the test more than once
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
The number of significant figure is 5
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.
neither, an independent variable is a variable not being changed in the process of a science experiment. A variable in math cannot be described, only purpose of a variable is to take place of a number that you are trying to figure out in some equations. Others are equations with no solution.
false
The dependent variable is the variable in the experiment that changes. For example if you were trying to figure out which of the three fertilizers works the best on flowers your dependent variable would be the fertilizer and the independent variable would be the flowers.

You could say, "Today in our science experiment we had to figure out what the dependent variable was"

The variable that you change is the independent variable(which you change). This could be the amount of light, fertilizer or salt that you give to a plant to observe how it affects its growth. What you measure is the dependent variable(the variables that change due to the change in independent variable) eg mass of the plant each day or week, number of leaves or height. All other variables are called the control variables(variables that are constant throughout the experiment). These make the experiment a "fair test". In the above experiment if you were to vary the amount of salt in the soil then each plant must be given the same amount of light, fertilizer, water etc.
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
Dependent variable is the one that is the same and independent is the one that is being changed to see how it affects the dependent variable. Example: You want to discover what makes your dog hate his/her dog food. The food is Kibble and Bits so theres a mixture of vegetable, meat, and chicken. Dependent= your dog because you are trying to figure out why he/she isn't eating. The dog is what stays constant in this experiement (not changing) Independent= the dog food because in order to find out what your dog doesn't like you have to test if she/he hates the vegetable, meat or chicken pieces. So you separate them and this is what changes.
The dependent variable in Milgram's experiment was the level of obedience shown by the participants, measured by the maximum voltage of electric shocks they were willing to administer to another person when instructed by an authority figure.
An independent variable is a variable that is intentionally manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. The dependent variable, on the other hand, is the variable that is measured or observed to see how it responds to the changes made to the independent variable.
Well a manipulated variable is know to be something that changes throughout the experiment. However if you are trying to determine what happened or changed than YOU just simply figure out if it changed of color, texture, etc.
