Answer:
1100mL
Explanation:
V of a rectangular prism = l*w*h
= 12cm*20cm*5cm
=1100cm^3
1 cm^3 = 1mL
so 1100cm^3 = 1100mL
Answer:
3. Judgement may be affected by what we already think is true (prior knowledge).
Explanation:
This statement is the correct answer because someone could be bias. Due to biases, prior knowledge may be incorrect and our conclusion may be wrong if you don't focus on the data given.
Answer:- 0.134 seconds
Solution:- The speed is given as 
and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.
We need to do unit conversion from miles to meter as the speed is given in meter per second.
1 mile = 1609.34 meter
So, 
= 40072566 meters
Know that, 
It's rearranged to time as, 
Let's plug in the values in it:
= 0.134 seconds
So, the light would take 0.134 seconds to travel the mentioned speed. The answer without the unit is 0.134.
When you are doing a experiment, you are testing if your hypothesis is correct or false. If your hypothesis is false, you have to disgard it. If it is correct, you have to do many more parallels, and if they also confirm your hypothesis, your hypothesis can become a theory.
