Because of the constant and relatively low speed, a cable car's potential to cause harm in an accident can be underestimated.

Because subwoofers are generally limited to a bandwidth of no higher than 150 Hz, the switching speed for the amplifier does not have to be as high as for a full range amplifier, and simpler designs could be utilized.

Because of helium's relatively low molar ( atomic ) mass, its thermal conductivity, specific heat, and sound speed in the gas phase are all greater than any other gas except hydrogen.

Because speed is such an important factor of the approach, it is not surprising that many long jumpers also compete successfully in sprints.

Because of the symmetry, after the collision both must be moving away from the center of mass at the same speed.

Because the magneto has low voltage output at low speed, starting an engine is more difficult.

Drawbacks: Because of the nature of the pump, the clearance between the rotating pump and the outer edge must be very close, requiring that it rotates at a slow, steady speed.

Because the camshaft speed is nearly zero before the engine is started, an electric pump is used.

Because most of the engineering skill of British Rail had been sold off into the maintenance and renewal companies, Railtrack had no idea how many Hatfields were waiting to happen, nor did they have any way of assessing the consequence of the speed restrictions they were ordering-restrictions that brought the railway network to all but a standstill.

Because of works connected with the Marmaray and Istanbul-Ankara high speed line there are currently no rail services linking Istanbul with the rest of Anatolia.

Because speed and range were severely limited underwater while running on battery power, U-boats were required to spend most of their time surfaced running on diesel engines, diving only when attacked or for rare daytime torpedo strikes.

Because the spectrum from Planck's law of black body radiation takes a different shape in the frequency domain from that of the wavelength domain, the frequency location of the peak emission does not correspond to the peak wavelength using the simple relationship between frequency, wavelength, and the speed of light.

Because they have evolved for short bursts of extreme speed at the expense of their power, they cannot defend themselves against most of Africa's other predator species.

Because cheetahs rely on their speed to obtain their meals, any injury that slows them down could essentially be life threatening.

Because of its speed, a healthy adult cheetah has few enemies.

Because far less printhead motion was involved than in a conventional dot matrix printer, these printers were much faster than dot matrix printers and were competitive in speed with formed-character line printers while also being able to print dot-matrix graphics as well as variable-sized characters.

Because of this limitation, propellers are favoured for planes which travel at below mach. 5, while jets are a better choice above that speed.

Because of this, line-drawing, arc-drawing, and blitting had to be performed by the application to achieve acceptable speed, which was usually done by bypassing the BIOS and accessing video memory directly.

Because erase cycles are slow, the large block sizes used in flash memory erasing give it a significant speed advantage over old-style EEPROM when writing large amounts of data.

Because of commercial emphasis on taste, speed, product safety, uniformity, and low cost, fast food products are made with ingredients formulated to achieve an identifiable flavor, aroma, texture, and " mouth feel " and to preserve freshness and control handling costs during preparation and order fulfillment.

Because a number of people were interested in using the FORTRAN language and yet wanted to obtain the speed of the MAD compiler, a system called MADTRAN ( written in MAD ) was developed.

Because such waves conserve the amount of energy they transmit through any spherical boundary surface drawn around their source, and because such surfaces have an area that is defined by the square of the distance from the source, the power of EM radiation always varies according to an inverse-square law.

Because each part ( electric and magnetic ) of the EM field in the far-field region is produced by a change in the other part, the ratios of electric to magnetic field strength are fixed and unvarying in the far-field.

Because electromagnetic ( EM ) radiation can be conceptualized as a stream of photons, radiant energy can be viewed as the energy carried by these photons.

Because the energy of each photon of EM radiation is proportional to its frequency, gamma rays have sufficient energy that they are typically observed by counting individual photons.

( Because of their high energy, gamma-ray photons are generally counted individually, whereas the lowest energy forms of EM radiation ( e. g., radio to sub-millimeter ) are observed as electromagnetic waves consisting of many low-energy photons.

Because the wavelength for even the smallest of macroscopic objects is extremely small, diffraction of matter waves is only visible for small particles, like electrons, neutrons, atoms and small molecules.

Because the reflected and incident waves propagate in the same medium and make the same angle with the normal to the surface, the amplitude reflection coefficient is related to the reflectance R by

Because waves at different frequencies propagate at differing phase velocities in dispersive media, for a large frequency range ( a narrow envelope in space ) the observed pulse would change shape while traveling, making group velocity an unclear or useless quantity.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Because seismic waves commonly propagate efficiently and interact with internal structure, they provide high-resolution noninvasive methods for studying Earth's interior.

Because of their high amplitude to wavelength ratio, ultrasonic waves commonly display nonlinear propagation.

Because of the reflection, these second waves appear to come from a second antenna behind the plane, just as a visible object in front of a flat mirror forms a virtual image that seems to lie behind the mirror.

Because it is exposed to the generally westerly winds and waves of the Pacific, seas and weather in Juan de Fuca Strait are, on average, rougher than in the more protected waters inland, thereby resulting in a number of small-craft advisories.

Because polyethylene was found to have very low-loss properties at very high frequency radio waves, commercial distribution in Britain was suspended on the outbreak of World War II, secrecy imposed and the new process was used to produce insulation for UHF and SHF coaxial cables of radar sets.

Because of its close proximity to the Philadelphia area, Chester County has experienced large " waves " of development due to suburbanization.

Because of the change in velocity of seismic waves it is believed that on continents at a certain depth sial becomes close in its physical properties to sima, and the dividing line is called the Conrad discontinuity.

Because of this amplification effect, a shock wave is very intense, more like an explosion when heard ( not coincidentally, since explosions create shock waves ).

Because of their large wavelengths, VLF radio waves can diffract around large obstacles and so are not blocked by mountain ranges, and can propagate as a ground wave following the curvature of the Earth.

Because of their long wavelength, low frequency radio waves can diffract over obstacles like mountain ranges and follow the curvature of the Earth.

Because of the rough and random pattern of a riverbed, waves are often not perpendicular to the river's current.

Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere, called " skip " or skywave propagation, these frequencies can be used for long distance communication, at intercontinental distances.

Because both the rod and the fly line are tapered the smaller amount of mass will reach high speeds as the waves in rod and line unfurl.

This bending happens because each layer of the ionosphere has a refractive index that varies from that of the others. Because of the differing heights of refraction, or apparent reflection, the radio waves hit the earth surface at different points hence generating the skip distance.

Because P waves are the fastest seismic waves, they will usually be the first ones that the seismograph records.

Because these waves are not guided but diverge, in free space these systems have attenuation following an inverse-square law, inversely proportional to distance squared.

Because of waves of terrorist attacks ( most notable is the road massacre of 37 civilians ) coming from the PLO in Lebanon, the IDF undertook Operation Litani, a wide-ranging and thorough anti-terrorist operation that included occupying part of Southern Lebanon in 1978.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
