Which one of the following is the dimension of mass density * 1?

Explanation: Mass Density(p) is defined as the mass(m) per unit volume(V ), i.e., [p] = [m]/[v] = [m] /[L3] = [ML-3]. 6.

What are the dimensional Formulae of I density II force?

Thus, dimensional formula for force is [M1L1T – 2]. SI unit of force is kg m s – 2. (2) Dimensional formula for mass is [M1L0T0] and dimensional formula for volume is [M0L3T0]. Thus, dimensional formula for density is [M1L−3T0].

What is the SI unit and dimension of density?

The SI unit for density is: kilogram per cubic metre (kg/m3). Density = mass/volume = M/L² = [ML-²T°] Density is measured in kilogram per cubic metres (kg/m^3). In order to change a unit into dimension, mass in kg, is represented by M, length in metres, by L and time in seconds by T. Density is mass per unit volume.

What is dimension of G?

Gravitational Constant (G) = F × r2 × [Mm]-1. Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

How do you find the dimension of density?

Dimension Formula of Density

1. Density typically means mass divisible by volume i.e. mass/volume.
2. Now, the Dimension of Mass = (M1)
3. Now, the Dimension of Volume = (L3)
4. Dimension of Density= {M1} / {L3} = M1/ L-3.
5. Unit of Density is kg/m3.

What is the dimension of area?

Dimensional Formula:

Physical quantity	Unit	Dimensional formula
Area (length × breadth)	m 2	L 2
Boltzmann’s constant	JK –1	ML 2T –2θ –1
Bulk modulus (ΔP × (V/ΔV))	Nm –2, Pa	M 1L –1T –2
Calorific value	Jkg –1	L 2T –2

What is the dimension of radius?

For example, if r is the radius of a cylinder and h is its height, then we write [r] = L and [h] = L to indicate the dimensions of the radius and height are both those of length, or L. Similarly, if we use the symbol A for the surface area of a cylinder and V for its volume, then [A] = L2 and [V] = L3.

How do you write dimensions of density?

Therefore, density is dimensionally represented as [M1 L-3 T0].

What is the dimension of K?

So k = F/x, k = [MLT^-2]/[L], therefore the dimension of k is [MT^-2].

What is the dimension of C?

(i) Yes, C is a vector space over R. Since every complex number is uniquely expressible in the form a + bi with a, b ∈ R we see that (1, i) is a basis for C over R. Thus the dimension is two.

What is the dimension formula?

Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. These will specify the nature of the unit and not its magnitude.

What is the formula to calculate density?

The formula for calculating density is mass divided by volume (density = mass/volume). Density is a measure of how much mass an object has per a given volume. Volume refers to the amount of three-dimensional space occupied by an object.

What are two ways to determine density?

Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object’s mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

What are two things determine density?

Concentration of atoms. An important factor in determining the density of a material is its mass for a given volume.

Change in volume. The volume of a material can change with temperature and pressure.

Change of phase or state.

What are two units used to measure density?

As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density.
