In the late 1700s, traffic in the United States was RHT based on teamsters' use of large freight wagons pulled by several pairs of horses. The wagons had no driver's seat, so the (typically right-handed) postilion held his whip in his right hand and thus sat on the left rear horse.

The radius of the tunnel and the strength of the magnetic field determine the top speed of the charged particles that the LHC's magnets could steer around the collider ring. ... This is the main reason why protons are used in the LHC rather than electrons: to be able to achieve higher energies than before.

They cannot be the same thing because they have different units. Centripetal acceleration ac=v2/R=ω2R has units of m/s2, while angular acceleration α=dω/dt has units of radian/s2.

So in LVH, we expect the 'R' waveforms to be enlarged/tall in these leads (conversely, we expect the 'S' waves to be deep in the right ventricular leads, that is V1 and V2). Suggested voltage criteria for LVH include: The sum of the S wave in v1 or v2, PLUS the R wave in v5 or 6 ≥35 mm.

Rh blood type checks for the Rh antigen (also called the Rh factor) on red blood cells. If your red blood cells: Have the Rh antigen, your blood is Rh-positive. Do not have the Rh antigen, your blood is Rh-negative.

They also label them as either rhesus (Rh) positive or Rh negative to denote the presence or absence of an antigen called Rh factor. For example, a person with O+ blood does not have A or B antigens on the surface of the cells but does have Rh factor. In contrast, O- blood has no A or B antigens and no Rh factor.

HI there, LT1 or LT4 is a generation 2 small block and is engineered for higher rpm power. LS1 is a generation 3 small block and more engineered for all around power and performance.

Zr and Hf exhibit similar properties due to lanthanoid contraction. Electrons present in f subshell didn't do good shielding due to which with the increasing atomic number or increasing effective nuclear charge size gets constricted and size of Halfenium and Zirconium becomes almost equal.

The key difference between D and L glucose is that in D-glucose, three hydroxyl groups and one hydrogen group are in the right side whereas, in L-glucose, the three hydroxyl groups and one hydrogen group are in the left side. ... Therefore, the key difference between D and L glucose lies in their structure.

No. They are called stoichiomers also known as anomers. Since they are not the mirror images to each other but only one hydorxyl group is changing position such as alpha facing down and the beta facing up. Actual enantiomers are D glucose and L glucose.!

In 2H (two-wheel drive, high range) two wheels, usually the rear, are driving your vehicle. You use 2H for normal road driving. In 4H (four-wheel drive, high range) all four wheels are driving your vehicle. ... In 4L (four-wheel drive, low range), all four wheels are driving your vehicle and a low gear ratio is being used.

The L stands for "long wheelbase". The Li has a longer wheelbase and wider rear doors. The additional length is used entirely to make sitting in the rear more comfortable. So the Li is for people who like being driven by a chauffeur, while the i is for people who like to drive themselves.

Positive or negative blood If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative. 77% of our donors are Rh D positive. There are four other main antigens in the Rh system.

Solution : The resistance coils are double would to avoid induction effects Magnetic field deu to current in one half of the coil is cancelled by magnetic field due to current in the other half of the coil (which is in opposite direction).

There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an electron from the 4s orbital is excited and rises to a 3d orbital.

Antigens (on the surface of the red blood cells): Rh+ indicates there are Rh antigens. Antibodies (in the blood plasma): B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
