A "seismograph" is a machine designed to detect and record
the tiny motions of the ground caused by earthquakes.

"seism-" . . . . . related to earthquakes

"graph" . . . . . picture or drawing  .

More than one seismograph is a bunch of 'seismographs' ... no apostrophe.

The picture that the seismograph draws is a ' seismogram ' .

Heat gained minus work fine is equal to what?
Zina [86]

Heat transferred - Work done = Internal Energy

Explanation:

  • If there is more heat transfer than the work done, the energy difference is called internal energy
  • The first law of thermodynamics equation is given as ΔU=Q−W where, ΔU = Internal energy; Q = Heat transfer; W = Work done
  • Heat = transfer of thermal energy between two bodies at different temperatures
  • Work = force used to transfer energy between a system and its surroundings
  • The First Law of Thermodynamics states - energy can be converted from one form to another with the interaction of heat, work and internal energy
  • Energy cannot be created nor destroyed

Two pipes of equal length are each open at one end. Each has a fundamental frequency of 470 Hz at 310 K. In one pipe the air tem
Tresset [83]

Answer:

Given:

Fundamental frequency: 470Hz

T1:310k,T2:315k

Calculating velocity

Recall v=(331m/s)✓[T1/273k)

V=331✓(310/273)

V1=331*(1.0656)=352.72m/s

V2=331✓(315/273)=355.5m/s

Fundamental frequency=4L

F2=F1(V2/V1)

F2=470(355.5/352.72)=474.4Hz

Beat=[F2-F1]=474.4-470=4.4Hz

what output force is generated when an input force of 630 n is applied to a machine with a mechanical advantage of 3
Marta_Voda [28]
The mechanical advantage is the factor by which
the machine multiplies the input force.

If the MA is 3 and the input force is 630N, then
the output force is

           (3) x (630N) = 1,890N
