The first ariplanr was made December 17, 1903
Answer:
a)the possible frequencies are 521hz ,522hz, 523, 524hz,525hz
b) 526hz
c)0.989 or a 1.14% decrease in tension
Explanation:
a) While tuning a string at 523 Hz,piano tuner hears 2.00 beats/s between a reference oscillator and the string.
The possible frequencies of the string can be calculated by
fl=f' - B
where
fl= lower limit of the possible frequency
f'= frequency of the string
B= beat heard by the tuner
fl= 523hz + Or - (2beats/secs * 1hz/1beat per sc)
fl= 521hz or 525hz
So the possible frequencies are 521hz ,522hz, 523, 524hz,525hz
b)fl=f' - B
523hz= f' - 3
f'= 523 + 3= 526hz
c) The tension is directly proportional to the square of the frequencies
T1/T2 =f1^2/f2^2
523^2 / 526^2 = 0.989 or a 1.14% decrease in tensio
B. opposite charge and smaller mass
Answer:
you mean this halo right
Explanation:
Halo is an American military science fiction media franchise managed and developed by 343 Industries and published by Xbox Game Studios. The franchise and its early main installments were originally developed by Bungie. The central focus of the franchise builds off the experiences of Master Chief John-117, one of a group of supersoldiers codenamed Spartans, and his artificial intelligence (AI) companion, Cortana.
The original trilogy centers on an interstellar war between humanity and an alliance of aliens known as the Covenant. The Covenant, led by their religious leaders called the Prophets, worship an ancient civilization known as the Forerunners, who perished while defeating the parasitic Flood. The eponymous Halo Array are a group of immense, habitable, ring-shaped superweapons that were created by the Forerunners to destroy the Flood, but which the Covenant mistake for religious artifacts that, if activated, would transport them on a Great Journey to meet the Forerunners. They are similar to the Orbitals in Iain M. Banks' Culture novels, and to a lesser degree to author Larry Niven's Ringworld concept.[1][2][3][4]
The games in the series are critically acclaimed, with the original considered the Xbox's "killer app".[5] This led to the term "Halo killer" being used to describe console games that aspire, or are considered, to be better than Halo.[6] Fueled by the success of Halo: Combat Evolved, and by marketing campaigns from publisher Microsoft, its sequels went on to record-breaking sales.[7][8][9] The games have sold over 65 million copies worldwide, with the games alone grossing almost $3.4 billion.[10][11][12] Halo has since become one of the highest-grossing media franchises of all time. These strong sales led to the franchise's expansion to other media; the Halo Universe now spans multiple best-selling novels, graphic novels, comic books, short movies, animated movies and feature films, as well as other licensed products.

Answer:
h = 2.64 meters
Explanation:
It is given that,
Mass of one ball, 
Speed of the first ball, 
(upward)
Mass of the other ball, 
Speed of the other ball, 
(downward)
We know that in an inelastic collision, after the collision, both objects move with one common speed. Let it is given by V. Using the conservation of momentum to find it as :
V = 7.2 m/s
Let h is the height reached by the combined balls of putty rise above the collision point. Using the conservation of energy as :
h = 2.64 meters
So, the height reached by the combined mass is 2.64 meters. Hence, this is the required solution.
