Answer:
Explanation:
The resistance of a wire is given by the equation:
where
is the resistivity of the material
L is the length of the wire
A is the cross-sectional area of the wire
In this problem, we have a wire of platinoid, whose resistivity is
The length of the wire is
L = 7.0 m
And its radius is
, so the cross-sectional area is
Solving for R, we find the resistance of the wire:
Answer:
binomial nomenclature.
Explanation:
This means that an organism's scientific name is a combination of two terms.
The first is the name of the organism's genus, and the second is the name of the organism's species
together the genus and the species create the name of a single organism.
The act of using senses or tools to gather information is called "observation." In scientific method, it is very essential to have this one. Through observation, we are able to get what we wanted to get using our senses and other tools. This process is very tedious if the field that you are studying is quite complicated. Hope this Helps!

Answer;
-Physical model
A physical representation of a real object, such as a globe of the world, is a physical model.
Explanation;
-A physical model is a simplified material representation, usually on a reduced scale, of an object or phenomenon that needs to investigated.
-The model can be used to simulate the physical conditions involved (temperature, waves, speed etc.) and to predict the particular constraints of the situation.
