The fundamental frequency in a pipe closed at one end is 663 Hz. what is the frequency, in hertz, of the m = (2x5)+1) order harmonic? Notes: (the weird formula was just to guarantee that you always get an odd number.. i. e. if your number is 2, then the harmonic is 5. If the number in the formula is 3, then your harmonic is 7)

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Explain why electric current cannot exist if a current doesn't have a voltage source.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
