| 41. | If you treat the wavelength of the laser as unit length dimension, how many wavelengths are the two objects apart?
|
| 42. | Second, let be the external force per unit length acting on a small segment of a chain as a function of.
|
| 43. | In the case of the standard catenary, where the chain has mass per unit length and is the acceleration of gravity.
|
| 44. | We find the total energy transferred by integrating the expressions for the time rate of change of internal energy per unit length:
|
| 45. | Referring to the circuit diagram on the right, these scales can be determined from the resistances and capacitances per unit length.
|
| 46. | Force perpendicular to the boosts transforms the same as the unit lengths, so their ratio is the same in all frames.
|
| 47. | The pitch of a string can also be varied by changing the linear density ( mass per unit length ) of the string.
|
| 48. | The larger the cross-sectional area of the conductor, the more electrons per unit length are available to carry the current.
|
| 49. | The notion of restricting orthogonal pairs of vectors to only those of unit length is important enough to be given a special name.
|
| 50. | Engineering and medical difficulties made the Panama Railway the most expensive railway ( per unit length of track ) built at the time.
