blue end of the spectrum
middle of the spectrum
The light-gathering capacity of a telescope is dependent upon the:
magnification
focal length
size of human iris
area of aperture
Answer:
1) blue end of the spectrum
2) area of aperture
Explanation:
1) The electromagnetic spectrum encompases a wide range of frequency (ν) and wavelength (λ) that includes gamma rays, x-rays, ultra violet(UV), visible, infra red (IR), microwaves and radiowaves. The wavelength increases from gamma rays to radio waves.
The wavelength perceivable by human eyes lies in the UV-visible region which extends from 380 nm in the blue to 740 nm in the red.The shortest wavelengths occur in the blue end of the spectrum which also have the highest energy. In contrast, longer wavelengths occur on the red which have lower energy.
2) The light gathering capacity of a telescope is dependent upon its area of aperture. Larger the area, greater is the light gathering power which implies that the telescope has the capability of detecting weak or faint objects.
The area of the aperture is essentially the area of the objective of the telescopic lens which is given as:
where D = diameter of the lens
1) blue end of the spectrum
2) area of aperture
(1) The president did not have the power to veto
legislation.
(2) The legislative branch enacted an unfair tax
program.
(3) The Supreme Court refused to pay
Revolutionary War debts.
(4) The national government was too weak to
solve the nation’s problems.
Answer : Option 4) The national government was too weak tosolve the nation’s problems.
Explanation : The main reason for the Federalists wanted to replace the Articles of Confederation because they believed that the structure the Articles which were laid out did not provided enough power for the federal government to effectively solve the nation's problems. It projected the image of the federal government being weak for solving nation's problem.

The element with 11 protons, 11 electrons, and 12 neutrons is an Isotope of Sodium, specifically Sodium-23. The atomic number, determined by the number of protons, identifies the element.
The element described here, with 11 protons, 11 electrons, and 12 neutrons, is Sodium. The number of protons in an atom defines the atomic number, and thus identifies the element. In this case, the atomic number is 11, which corresponds to Sodium on the periodic table. Neutrons contribute to the mass number, but not the identity of the element. Therefore, an element with 11 protons and 12 neutrons is an isotope of Sodium. Sodium normally has 11 neutrons, but in this case, it has 12, which makes it an isotope of Sodium commonly referred to as Sodium-23.
