Sum of masses = 1 + 1.5 + 2 + M = 4.5 + M
x-coordinate;
(1*2 + 1.5*1 + 2*2 – M)/(4.5 + M) = 1
4.5 + M = 7.5 – M
2M = 3
M = 1.5 kg.

Sum of masses = 3 + 2 = 5 kg
Centre of mass from 3 kg ball = (6 x 2) / 5
= 2.4 m.

The mass of a hydrogen atom is 1.6736×10^-24 g. When converted in terms of amu, 1.6736×10^-24 g should be divided by 1.66056×10^-24 g. 1.6736×10^-24 g/1.66056×10^-24 g = 1.0078 amu = 1.008 amu. This the process to measure any atomic mass in amu.

Given that, carbon-12 is of 70% and carbon-14 is of 30%. In order to find avg atomic mass, you should add the products of multiplications 12 with 70/100 and 14 with 30/100. 12 x 0. 7 = 9.8; 14 x 0.3 = 4.2. Now adding them 9.8 + 4.2 = 14.

As Cl in NaCl can’t exist in the solid state, we can only calculate it’s formula mass. the individual mass of sodium is 23 u, whereas that of chlorine is 35.5 u. Together formula mass f Sodium chloride is the sum of individual masses, 23 + 35.5 = 58.5 u.

The human body has various types of cells which have different morphologies and perform specific functions. The cells have mainly three types of movement- amoeboid, ciliary and muscular.

The most common types of movements seen in cells of the human body are amoeboid, ciliary and muscular. Amoeboid movement is carried out by pseudopodia, which are formed from the protoplasm.

The ciliated epithelium of the inner surface of the trachea, the movement of ova through the oviducts and the vasa efferentia show ciliary movement. The vas deferens does not show ciliary movement.

The neural system, the muscular system and the skeletal system influence locomotion and the coordinated activity of these systems is required for locomotion. The integumentary system does not influence it.

The most common types of movements seen in cells of the human body are amoeboid, ciliary and muscular. Muscular movement relies on the contractile property of muscles, which is essential for locomotion.
