Answer:

Basically, a variable is any factor that can be controlled, changed, or measured in an experiment. It's anything that can be changed in the experiment.

Explanation:

Scientific experiments have several types of variables. The independent and dependent variables are the ones usually plotted on a chart or graph, but there are other types of variables you may encounter. The presence/absence of the chemical is the independent variable. The health of the (ex:)rat (whether it lives and can reproduce) is the dependent variable.

when you started the activity, the can was open to the air outside tge can. how did the air pressure inside the can compare to t

aliya0001 [1]

The air pressure inside the can is lower compared to that of outside air pressure.

Explanation:

In general, the air pressure of an already opened can will be the same as the outside pressure.
Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
If the can opens, air inside the can push the top and escapes to the outside.
This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.

When the temperature of the air is 25°C, the velocity of a sound wave traveling through the air is approximately

Vitek1552 [10]

Answer ; The correct answer is : 346 m/s .

Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .

Speed of sounds depends on factors like medium , density , temperature etc .

Effect of Temperature on speed of sounds :

When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .

The speed of sounds at 0⁰C is 331 $\frac{m}{s}$
