The radius of the nth orbit is given by the formula: r n = n 2 * a 0. In this case, we are looking for the radius of the third orbit. Plugging in n = 3 into the formula, we get: r 3 = 3 2 * a 0 r 3 = 9 * a 0 Therefore, the radius of the third orbit is 9 times the Bohr radius, or 9 a 0. Hence, the correct answer is (A) 9 a 0.

Choke coil is preferred over resistance in ac circuit this is because, large value of self inductance of choke coil. and hence, the power dissipation for a choke coil is 0. That’s why, A choke coil is preferred to a rheostat in ac circuit as it consumes almost zero power.

Immigration is the migration of an individual into a place. When individuals immigrate to a new location, they increase the population within that area. When individuals immigrate to a new location, they increase the population within that area.

High cutting speed; High tool-chip friction; Significant depth of cut. The segmented chips provide clean surface finish in brittle metals, easy chip disposal, longer tool life, and reduced power consumption. In the case of ductile metals, the segmented chips usually result in poor surface finish and lower tool life. Continuous Chips

A hiding adjustment factor was developed for the Ackers-White method by Profitt and Sutherland (1983), and is included in RAS as an option. The hiding factor is an adjustment to include the effects of a masking of the fluid properties felt by smaller particles due to shielding by larger particles.

Video transcript. - In the Bohr model of the hydrogen atom we have one proton in the nucleus. So I draw in a positive charge here and a negatively charged electron orbiting the nucleus, so kind of like the planets orbiting the sun. Even though the Bohr model is not reality it is useful for a concept of the atom.

Rh factor is a type of protein on the surface of red blood cells. When present, a persons blood type is Rh-positive (such as A+ or O+). When the Rh protein is absent, the blood type is Rh-negative (such as AB- or B-). Most people are Rh-positive and, in general, your Rh factor does not impact your life unless you need blood or are pregnant.

The rhesus factor, or Rh factor, is a protein that may be present on the surface of red blood cells (RBCs). If RBCs contain the Rh antigen, they are Rh-positive, and if not, they are.

The power factor defined by IEEE and IEC is the ratio between the applied active (true) power - and the apparent power, and can in general be expressed as: PF = P / S (1) where PF = power factor P = active (true or real) power (Watts) S = apparent power (VA, volts amps)

Pernicious anemia is defined as a type of vitamin B12 deficiency that results from impaired uptake of vitamin B-12 due to the lack of a substance known as an intrinsic factor (IF) produced by the stomach lining. Pernicious anemia is a condition caused by too little vitamin B12 in the body. It is one form of vitamin B12 deficiency anemia.
