Answer:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.
Explanation:
Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
Well one of the factors is that the species is poorly adapted to the their environment and die off
3^3 is the way you write 3³ when you don't have any way to write the ³ .
Whichever way you write it, it means " 3 · 3 · 3 " . That's 27 .
I don't know what would be considered "simplifying" it. Maybe " 3³ "is a little simpler, but you can't always write that if your computer or your word processor doesn't give you a way to write exponents.
" 3 · 3 · 3 " certainly is not any simpler than " 3^3 ", so that's not it.
" 27 " may be simpler.
Answer:
Attraction.
Explanation:
Charging by friction involves rubbing of objects against one another so that one loses electron(s), while the other gains the electron(s). Thus, the objects would have opposite charges after the process.
The glass test tube rubbed with silk loses electron, thus becomes positively charged. While the acrylic rob rubbed with paper towel becomes negatively charged. Since the two rods have opposite charges, then the interaction between them would be attraction. A force of attraction between the rods would be experienced while the rods are brought to a required close range.
