Answer:
D) crystalline solid that conducts current under certain conditions
Explanation:
A semiconductor is any crystalline solid material whose electrical conductivity is intermediary between that of insulators and conductors. That is, a semiconductor does not conduct like a conductor but does more than an insulator.
Based on this, a semiconductor is said to only conduct electricity under certain conditions as opposed to conductors that do so under any condition. Example of semiconductors are silicon, carbon, antimony, arsenic etc.
Answer:
Look below.
Explanation:
If additives are having negative effects on health and the environment, it would be wise to not use detergents containing these additives. These additives could threaten living things such as humans and animals.
<span>Using Newton’s 2nd
law, we can calculate for the force (F) required to give a mass 255kg an
acceleration of 3.5 m/s^2: </span><span>
F= ma</span>
<span>F= 255kg*3.5m/s^2 = 892.5 N </span>
892.5 was the force needed for the motorcycle alone. Taking
into account the total resistance of 400N:
total F = 892.5 N + 400 N
<span>total F= 1292.5 N</span>
Sphere A travels a horizontal distance of (10 m/s) <em>t</em> after time <em>t</em>, while sphere B travels a distance of (5 m/s) <em>t</em>. So sphere B lands on the floor some point between the table's edge and the point X (A).
