Evaluate the average of the square of the linear momentum of the quantum harmonic oscillator for the ground state and first two excited states. In evaluating integrals of this type, ∫f(x)dx=0[infinity]−[infinity]if f(x) is an odd function of x, ∫f(x)dx=[infinity]−[infinity]2∫f(x) dx[infinity]0if f(x) is an even function of x. The definition ofodd andeven functionsaref(-x) = -f(x) andf(-x) = f(x), respectively.

object 2 because all the other ones are wrong

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
