What is the thermal energy of an object?
a. its total temperature
b. the total potential energy of its particles
c. the total kinetic energy of its particles
d. the total kinetic and potential energy of its particles

I did the quiz, (D) "The total kinetic and potential energies of its particles" is correct.

Option (D) is correct. The thermal energy of any object is the sum of the kinetic energy as well as the potential energy of the object.

Explanation:

The total energy of the object at a particular temperature is defined in terms of the two parameters. The energy of the particles is given as the kinetic energy and the potential energy is due to the amount of heat stored in the object.

The object has the vibration energy stored in it and this energy of the object increases as the heat energy of the object is increased. Whereas the potential energy of the object is due to the amount of heat contained by the object.

The total thermal energy of the object always remains constant as the energy of the system is always conserved. The sum of the total amount of kinetic energy and the potential energy of the object remains constant and it is termed as the thermal energy of the object.

Thus, Option (D) is correct. The thermal energy of any object is the sum of the kinetic energy as well as the potential energy of the object.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
