Answer:
A new technology is invented that allows for new experimentation.
Explanation:
This should be the best situation because new technology helps scientists make more accurate and precise experiments, usually giving changes to the old experiments, and the discovery of newer parameters that could not have been found in the old experiment.
So new technology, more accurate and precise experiments, more parameters and conditions have been found, giving scientists a deeper understanding of what is happening, therefore giving a theory a high probability to change.
Answer:
amongst the properties that makes aluminium a metal is that it is malleable and ductile...and it has high melting and boiling points
I hope that helps
Explanation:
properties of metals include
1. high melting and boiling points
2 high densities
3 malleability and ductility
Explanation :
There are many types of simple machines i.e. lever, wedge, pulley, wheel and axle etc.
Fulcrum is the pivot point about which the lever turns. When the position of the fulcrum is shifted, the position of effort changes.
There are three classes of the lever as class 1, class 2 and class 3.
Class 1 includes seesaws and scissors.
class 2 includes wheelbarrow
class 3 includes tongs and tweezers.
