Physics: each of two or more atomic nuclei that have the same atomic number and the same mass number but different energy states.
chemistry: each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties.
Answer:
Step-by-step explanation:
A well defined set is one which is universally defined and accepted, you can easily define what the set is and what is not a member of the set.example is a set of integers between 1 and 30
A not well defined set is one which is ill defined set. example is a list of hit musical hit of 2019
I’m a bit confused confused, but the answer may be -2x^3 + 2x^2 - 2x +2
Work:
To solve this, take the equation for q and the equation for r, and multiply them together.
Use the distributive property to multiply them.
I’m not sure if this is right or not, so pls don’t get mad if it isn’t.
Thank you! :)

Answer:
t < 1.5
Step-by-step explanation:
Mon-Thu: 5.5 hours
each of the remaining 3 days: t hours each day
total time: 3t + 5.5
The total time must be less than 10 hours.
3t + 5.5 < 10
3t < 4.5
t < 1.5
