If an atom forms a molecule with another atom of itself then the result is a diatomic molecule.

Answer: Option A

<u>Explanation: </u>

It is known that combination of subatomic particles lead to creation of atoms and combination of atoms results in molecule formation. Molecules can be formed if two or more identical or non-identical atoms combine together due to inter/intramolecular forces acting between them. So the molecules can be termed as hetero or homo molecules.

Homo molecules arise when more than two identical atoms combine to form a molecule. So in the present case, if an atom is forming a molecule with another atom of itself then the result will be a diatomic molecule, where “di” states for “two” and atomic molecules means combination of two identical atoms will form a molecule, the best example for a diatomic molecule is  O_{2}.

Batman, whose mass is 89.5 kg, is holding on to the free end of a 13.4 m rope, the other end of which is fixed to a tree limb ab
astra-53 [7]

Answer:

8.2\times 10^{3} J

Explanation:

L = length of the rope connected = 13.4 m

\theta = Angle made by the rope with the vertical = 72.4°

h = height gained by the batman above the reference point  

Height gained by the batman above the reference point  is given as

h = L(1 - Cos\theta )

m = mass of batman = 89.5 kg

g = acceleration due to gravity = 9.8 ms⁻²

Work done against gravity is same as the gravitational potential energy gained by batman and is given as

W = mgh

W = mgL(1 - Cos\theta )

Inserting the above values

W = (89.5)(9.8)(13.4)(1 - Cos72.4 )

W = 8.2\times 10^{3} J

2. CaCl2 (s) + 2H20 ---&gt; Ca(OH)2 (aq) + 2HCl (g) + heat<br> Is it an endothermic reaction?
antoniya [11.8K]

Answer:

no

Explanation:

Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. ... Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you add calcium chloride to water, the solution heats.

What is the resultant of the two vectors shown?
Ksju [112]

Answer

correct answer is C

Head-to-tail method

Here head-to-tail method is employed to determine resultant of vectors.

Let horizontal component be 1 and let vertical component be 2

To add these two vectors. Move vector 2 until its tail touches the head of 1. The tail of resultant of these two vectors touch the tail of vector 1 and head of resultant vector will touch the head of vector 2.
