Example #2: Preservatives, like salt, help keep food fresh. Katie made 12 loaves of bread using the same recipe and baking method. In 6 of them she used salt, in 6 of
them she used no salt. After the loaves were baked, she placed each of the loaves in a
plastic bad and left them close together on the counter in the kitchen. Each day she
looked at them to see if any mold had started to grow.
What is the control group?
What is the experimental group?
What is the independent variable?
What is the dependent variable?

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

what is the question here. i think you messed up.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
