What is mass per unit length?
property>mass per unit length The mass per unit length is the linear density of a one-dimensional substance such as a wire or thread. Clearly if the SI unit were kg/m then most threads would have tiny values, so the SI unit is the more convenient Tex – the number of grams per 1000 metres.
What is mass per unit area?
The areal density (also known as area density, surface density, superficial density, or density thickness) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is: kilogram per square metre (kg. m−2)
How do you find mass per unit?
Mass per unit length is the weight/Length of object. You take a wire and calculate its weight and length. Divide both of them and you get mass per unit length. please upvote if you feel it’s satisfactory!
How do you find mass units?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
What is the formula unit mass of Na2CO3?
106 g/mole
What is the difference between molecular mass and formula unit mass?
Formula mass is defined as the sum of atomic masses of the ions present in the formula unit of an ionic compound whereas molecular mass is the sum of the atomic masses of the atoms in a molecule.
What is the formula unit mass of cacl2?
111 amu
How do you find formula units?
Once you know the number of moles of CaO , you can determine the number of formula units by multiplying the number of moles by 6.022×1023 . You need to determine the molar mass of CaO , which is the sum of the atomic weights of each element on the periodic table in grams/mole, or g/mol.
How do you find force per unit area?
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.
What is force per unit length?
The ratio F/l is the force per unit length between two parallel currents I1 and I2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and other plasmas.
What is force per unit charge?
Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.
What is unit of electric flux?
Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1.
What is the unit of electric intensity?
The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location.
What is dipole and its SI unit?
Electric dipole moment Dipole moment →P is a measure of strength of electric dipole. It is a vector quantity whose magnitude is equal to product of the magnitude of either charge and the distance between them. SI unit of dipole moment is coulomb-metre (cm).
What is SI unit and dimensional formula of dipole moment?
Or, M = [M0 L0 I1 T1]× [M0 L1 T0] = [M0 L1 T1 I1]. Therefore, the magnetic or electric dipole moment is dimensionally represented as [M0 L1 T1 I1].
What is the dimensional formula of moment?
Or, MOI = [M1 L0 T0] × [M0 L1 T0]2 = M1 L2 T0. Therefore, the moment of inertia is dimensionally represented as M1 L2 T0.
Why dipole moment is a vector quantity?
It is a vector since it points in one direction (from one charge to the other), has an associated magnitude and so on. In a way, when you consider a multipole expansion it makes sense, the monopole momentum is just the net charge (a scalar), the dipole momentum a vector and from then on matrix quantities.
Is dipole moment is scalar?
Electric dipole moment is the product of either charges or the distance between two equal and opposite charges. It is a vector quantity.
