The main characteris tics of explosives are: brisance and high explosiveness explosion volume , detonation activity , blast wave depth power and activity

The main characteristics of explosives are:<br /><br />A. Brisance and high explosiveness<br /><br />Explosives are substances that can undergo rapid oxidation or decomposition, releasing a large amount of energy in the form of heat and light. This energy is often accompanied by a shock wave, which can cause damage to surrounding structures and objects.<br /><br />B. Explosion volume, detonation activity, and blast wave depth<br /><br />Explosion volume refers to the amount of space occupied by the explosion, while detonation activity refers to the speed and intensity of the explosion. Blast wave depth refers to the distance over which the blast wave can cause damage.<br /><br />C. Power and activity<br /><br />Explosives can have varying levels of power, which refers to the amount of energy released during the explosion. Activity refers to the ease with which the explosive can be initiated or detonated.<br /><br />Therefore, the correct answer is A. Brisance and high explosiveness.
