Give an example of a scientific hypothesis. Explain how you would test it, and how it could be falsified (proved untrue).
kaheart [24]

my hypothesis is that If you drop a piece of buttered toast, it will land butter side down.


I tested it by dropping 10 pieces of buttered toast off the table and noted on which side it landed


It could be falsified cause I just made all of this up. In essence, it's like flipping a coin, 50/50 chance so I could say that 5 landed butter up and 5 landed butter down.

The compressor on an air conditioner draws 66.1 a when it starts up. the start-up time is about 0.388 s. how much charge passes
Ierofanga [76]
The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:
I= \frac{Q}{\Delta t}
where Q is the charge and \Delta t is the time. Re-arranging the formula, we have
Q=I \Delta t

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is \Delta t= 0.388 s, so the amount of charge that crosses a certain point of the circuit during this time is
Q=I \Delta t=(66.1 A)(0.388 s)=25.65 C
