Question

The mass of nucleus blank subscript Z end subscript X to the power of A end exponent is less than the sum of the mases of (A - Z) number of neutrons and Z number of protons in the nucleus The energy equivalent to the corresponding mass difference is known as the binding energy of the nucleus A heavy nucleus of mass M can break into two light nuclei of mass m1 and m2 M only if open parentheses m subscript 1 end subscript plus m subscript 2 end subscript close parentheses less than M Also two light nuclei of mass  m3 and m4 can undergo complete fusion and form a heavy nucleus of mass M “only if open parentheses m subscript 3 end subscript plus m subscript 4 end subscript close parentheses greater than M to the power of ´ ´ end exponent The masses of some netrural atoms are given in the table below.

The correct statement is

  1. The nucleusscriptbase L i end scriptbase presubscript 3 end presubscript presuperscript 6 end presuperscript can emit an alpha particle    
  2. The nucleus scriptbase L i end scriptbase presubscript 84 end presubscript presuperscript 210 end presuperscript can emit a proton    
  3. Deuteron and alpha particle can undergo complete fusion.    
  4. The nuclei scriptbase Z n end scriptbase presubscript 30 end presubscript presuperscript 70 end presuperscript and scriptbase L i end scriptbase presubscript 34 end presubscript presuperscript 82 end presuperscript can undergo complete fusion.    

The correct answer is: Deuteron and alpha particle can undergo complete fusion.

A physics lab is designed to study the transfer of electrical energy from one circuit to another by means of a magnetic field using simple transformers Each transformer has two coils of wire electrically insulated from each other but wound around a common core of ferromagnetic material The two wires are close together but do not touch each other.

The primary coil is connected to a source of alternating (AC) current The secondary coil is connected to a resistor such as a light bulb The AC source produces an oscillating voltage and current in the primary coil that produces an oscillating magnetic field in the core material This in turn induces an oscillating voltage and AC current in the secondary coil Student collected the following data comparing the number of turns per coil (N), the voltage (V) and the current (I) in the coils of three transformers
The primary coil of a transformer has 100 turns and is connected to a 120V AC source How many turns are in the secondary coil if there is a 2400 V across it
