Calculate the mass of a box.
<h3><u>Solution:-</u><u> </u></h3>
★Putting the values in the above formula,we get:
Thus,the mass of a box is 2 kg.
Answer:
Explanation:
Recall that density is defined as and that relative uncertainty is defined as where is the uncertainty in the measure and a the measure, To find the uncertainty when two physical quantities are divided, their relative uncertainties are added and then multiplied with the division result of the quantities.
We have:
To find the percent uncertainty, we multiply the relative uncertainty by 100%.

Answer:
Conductance
Explanation:
The conductance of an object tells us how much that object is able to allow the flow of electric current.
Conductance is the inverse of the resistance, which tells instead how much the object is able to oppose to the flow of electric current.
Conductance is related to the resistance by the equation:
(1)
where
G is the conductance
R is the resistance
The resistance of an object is given by
where
is the resistivity of the material
L is the length of the object
A is the cross-sectional area of the object
Substituting into (1), we find another expression for the conductance:
which means that:
- The larger the cross-sectional area of the object, the higher the conductance
- The longer the object, the smaller the conductance
