The interaction which will occur when the non sticky tape pieces are turned towards each other is attraction.
<h3>What is Attraction?</h3>
This involves the coming together of objects as a result of a force. When non-sticky sides of the tape are brought towards each other attraction takes place due to the sticky content.
This however wears off after some time thereby making it the most appropriate choice.

Answer:
666,480 Joules or 669.48 kJ
Explanation:
We are given;
- Volume of water as 2.0L or 2000 ml
but, density of water is 1 g/ml
- Therefore, mass of water is 2000 g
- Initial temperature as 20 °C
- Final temperature as 99.7° C
Required to determine the heat change
We know that ;
Heat change = Mass × Temperature change × specific heat
In this case;
Specific heat of water is 4.2 J/g°C
Temperature change is 79.7 °C
Therefore;
Heat change = 2000 g × 79.7 °C × 4.2 J/g°C
= 669,480 Joules 0r 669.48 kJ
Thus, the heat change involved is 666,480 Joules or 669.48 kJ
Answer:
there is no image there so i do not know
Explanation:
A bike rusting is an example of a chemical
change since rusting is a chemical reaction. New substances are formed from
this reaction. On the other hand, other choices given are just physical changes
because only the shape or the physical form of the substances are being
changed. An example of a physical change is cutting a paper.
hydrogen (H2),and oxygen (O2),, that is the answer
