A1.65-m-long wire having a mass of 0.100 kg is fixed at both ends. the tension in the wire is maintained at 23.0 n. (a) what are the frequencies of the first three allowed modes of vibration? hz hz (b) if a node is observed at a point 0.330 m from one end, in what mode and with what frequency is it vibrating? (select all that apply.) the frequency is the second state at 11.8 hz the frequency is the tenth state at 59.0 hz the frequency is the fifth state at 29.5 hz the frequency is the tenth state at 11.8 hz the frequency is the twentieth state at 118.1 hz the frequency is the fifth state at 14.8 hz

b.transmitters send radio waves, and receivers capture radio waves.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

answer; equivalent to a one(1) horsepower motor;
