An all female guitar septet is getting ready to go on stage. the lead guitarist, kira, who is always in tune, plucks her low e string and the other six members, sequentially, do the same. each member records the initial beat frequency between her low e string and kira's low e string.
to tune an instrument using beats, more information than just the beat frequency is needed. in addition to recording the initial beat frequency , each member, except diane, also records the change in the frequency (increase or decrease) when they increase the tension in their low e string.
rank each member on the basis of the initial frequency of their low e string.
rank from largest to smallest. to rank items as equivalent, overlap them.
a. aiko=3hz, fbeat increases
b. chandra=1hz fbeat decreases
c. evita=5hz fbeat decreases.
d. freja=3hz fbeat decreases.
e. buffy=4hz fbeat increases.

1134567 a jet with mass m = 1.1 ă— 105 kg jet accelerates down the runway for takeoff at 2 m/s2. 1) what is the net horizontal force on the airplane as it accelerates for takeoff? 2.2*10^5 n your submissions: 2.2*10^5 computed value: 220000submitted: saturday, january 26 at 2: 41 pm feedback: correct! 2) what is the net vertical force on the airplane as it accelerates for takeoff? 0 n your submissions: 0 computed value: 0submitted: saturday, january 26 at 2: 41 pm feedback: correct! 3) once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 95 m/s. what is the net horizontal force on the airplane as it climbs upward? n 4) what is the net vertical force on the airplane as it climbs upward? n 5) after reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. what is the net horizontal force on the airplane as it levels off? n 6) what is the net vertical force on the airplane as it levels off?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
