Answer: They are typically smaller than spiral galaxies.

Some show evidence for prior collision or close encounter with another galaxy.

They exhibit vigorous star-forming activity.

Irregular galaxies are typically smaller than spiral or normal ellipticals, of irregular form, and without spiral arms. Irr I galaxies are often characterized by lots of gas, dust, and associated star formation. Irr II galaxies have forms that indicate prior collisions or close encounters with other galaxies. Irregular galaxies are one of the most common types of galaxies.

Which of the following is true regarding a voltaic (or galvanic) cell? a) It can only be used with hydrogen. b) It produces elec
N76 [4]

Answer:

b) It produces electrical current spontaneously.

Explanation:

Cells capable of converting chemical energy to electrical energy and vice versa are termed Electrochemical cells. There are two types of electrochemical cells viz: Galvanic or Voltaic cells and Electrolytic cells. Voltaic cell is an elctrochemical cell capable of generating electrical energy from the chemical reaction occuring in it.

The voltaic cell uses spontaneous reduction-oxidation (redox) reactions to generate ions in a half cell that causes electric currents to flow. An half cell is a part of the galvanic cell where either oxidation or reduction reaction is taking place. Hence, the spontaneous production of electric currents is true about Voltaic/Galvanic cells.

Calculate the frequency of electromagnetic wave with the wave length 344nm ( hint: use dimensional analysis)
Svetlanka [38]
Frequency = speed of light
                      ---------------------------
                        wavelength 
 
                   =        3 x 10^8
                      ------------------------
                          344 x 10^-9
 
                   =          8.72 x 10^14 Hz.

Hope this helps!
