As the frequency of an ac circuit increases, the current first increases till it becomes maximum at resonance and then decreases. Which one of the following combinations of circuit elements are likely to comprise the circuit ?

The ratio of total energy to the kinetic energy of an electron in a Bohr orbit of the hydrogen atom is

An electron is accelerated through a potential difference of 144 V. The de-broglie wavelength associated would be approximately:

A tiny spherical oil drop of mass 8 mg is kept suspended by applying a potential difference of 100 V between two metallic plates kept separated by a distance 1 cm. The number of electrons on the oil drop are : (Take \( g = 10 \text{ ms}^{-2} \))

Magnetic moment of a thin bar magnet is 'M'. If it is bent into a semicircular form, its new magnetic moment will be :

To observe diffraction, the size of an obstacle

When photons travel through crossed electric and magnetic field, perpendicular to both the fields then they are? Mock Test Generation

Read the passage carefully and answer
Carbohydrates are essential for both plants and animals. Some common examples of carbohydrates are glucose, fructose, sucrose, glycogen, cellulose and starch. They form a major portion of our food. Honey has been used for a long time as an instant source of energy in Ayurvedic medicine. Carbohydrates are used as storage molecules in both plants and animals. The cell wall of bacteria and plants is made of cellulose. We use cellulose in the form of wood for making furniture and as cotton fiber for clothing. They also provide raw material for textiles,
paper, lacquers, and breweries. Carbohydrates are classified as Monosaccharides, Oligosaccharides and Polysaccharides on the basis of their behavior towards hydrolysis. Monosaccharides cannot be hydrolyzed further to simpler units whereas oligosaccharides can yield 2-10 units of monosaccharides on hydrolysis. Polysaccharides, which are non-sugars yield a large number of monosaccharide units on hydrolysis.
Answer the following questions about carbohydrates:
Hydrolytic products of maltose are?

Identify the correct statements.
(A) The energy (E) and momentum (p) of a photon are related by p = E/c.
(B) The electrons and photons of the same wavelength, possess the same momentum.
(C) One photon having energy more than work function can emit one photo electron.
(D) Photons do not carry momentum.
