It has a neutral charge which means it is equal.
Answer:
Explained
Explanation:
Resistance R in a current flow through an object is given by
ρ = resistivity of the material
L= length of the object
A= area of cross section
clearly resistance is directly dependent on length of the object.This means greater the length larger will be resistance to current.
thermal resistance R_th is given by
L= length of the object
A= area of cross section
K = Conductivity of the material
thermal resistance is also is directly dependent on length of the object.This means greater the length larger will be resistance to current.
If the volume is the same and the temperature increases, then the molecules will move around faster and bump more against the balloon, so the pressure will increase.
Answer:
Substances that cannot be broken down into other substances are called elements.
Explanation:
Elements are pure substances that cannot be broken down into other elements through any non-nuclear means. For example: hydrogen, helium, lithium, beryllium, boron, and carbon.
A list of the elements can be found in a periodic table.
Answer:
minimum interface length = 1.36 mm
Explanation:
given data
weight of the bug = N
solution
we will apply here Surface Tension formula that is
Surface Tension ,σ = Force ÷ length ........................1
and we consider here surface tension for water is 7.34 × N/m
so that here minimum interface length needed to support the bug is
minimum interface length = Force ÷ σ
minimum interface length = ÷ 7.34 ×
minimum interface length = 1.36 mm
