Answer:
Because their properties like conductivity, electronic configuration and ionization lies in between the metals and nonmetals.
Explanation:
There are a total of six elements that fall in the category of semiconductors.
Namely these are boron, silicon, germanium, arsenic, antimony, and tellurium.
These elements look like metals i.e. are lustrous but do not conduct electricity so well like a metal does.
Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form mono-atomic anions.
You know that the formula for finding horizontal displacement is;
s=uₓt
s=(5 m/s)(3s)
s=15 m
Therefore, the ball travelled 15 m.
Hope I helped :)
Distance traveled(in a certain direction) and time
Velocity is all about direction traveled in comparison to speed which is just distance with out direction.
Hope this helps you
Answer:
The net force is 392N, pointing down.
Explanation:
The net force is the sum of all forces acting on the rock, namely the gravity ("+" acting downward) and the friction force due to air resistance ("-" acting upward):
The net force is 392N and pointing down (positive)/
