Let us assume Jacob’s current age is x and his son’s current age is y.

Five years hence, Jacob’s age = x + 5 and his son’s age = y + 5

As per question;

x + 5 = 3(y + 5)

Or, x + 5 = 3y + 15

Or, x = 3y + 15 – 5 = 3y + 10

Five years ago, Jacob’s age = x – 5 and his son’s age = y – 5

As per question;

x – 5 = 7(y – 5)

Or, x – 5 = 7y – 35

Or, x = 7y – 35 + 5 = 7y – 30

Substituting the value of x from first equation in this equation, we get;

3y + 10 = 7y – 30

Or, 3y + 10 + 30 = 7y

Or, 7y – 3y = 40

Or, 4y = 40

Or, y = 10

Substituting the value of y in first equation, we get;

x = 3y + 10

Or, x = 3 x 10 + 10 = 40

Hence, Jacob’s age = 40 years and son’s age = 10 years

The type of reaction in which two or more reactants are combine to form single product is called combination reaction

Yogita Ingle 5 years, 4 months ago

A combination reaction is a general category of chemical reactions. It may be defined as a chemical reaction in which two or more substances combine to form a single substance under suitable conditions.

Combination reactions are also known as synthesis, because in these reactions new substances are synthesized.

2 Na(s) + Cl2 (g)  →  2NaCl(g)

Namrata Patil 5 years, 4 months ago

When two or more elements combine to form one product then the reaction is called combination reaction.

With age ,Nelson Mandela realized that he had a lot of responsibilities towards his people, his community and his country. As a boy, Mandela did not have a hunger for freedom because he thought that he was born free. He believed that as long as he obeyed his father and abided by the customs of his tribe, he was free in every possible manner. He had certain needs as a teenager and then certain needs as a young man.He slowly understands that it is not just his freedom that is being curtailed, but the freedom of all blacks. It is after attaining this understanding that he develops a hunger for the freedom of his people. Thus , age and experience made his perspective more wide.

Whenever a current carrying conductor comes under a magnetic field, there will be a force acting on the conductor. The direction of this force can be found using Fleming’s Left Hand Rule (also known as ‘Flemings left-hand rule for motors’). Similarly if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor. The direction of this force can be found using Fleming’s Right Hand Rule. In both Fleming’s left and right hand rules, there is a relation between the magnetic field, the current and force. This relation is directionally determined by Fleming’s Left Handrule and Fleming’s Right Hand rulerespectively. These rules do not determine the magnitude but instead show the direction of any of the three parameters (magnetic field, current, force) when the direction of the other two parameters is known. Fleming’s Left-Hand rule is mainly applicable to electric motors and Fleming’s Right-Hand rule is mainly applicable to electric

Some 20,000 years ago, early humans ground up earth, charcoal, and minerals, and used the colored powders to create images on cave walls. Sometimes the powders were mixed with saliva or animal fat to form a fluid, which was blown through reeds, or applied with fingers.

Salts are classified as acidic salt or basic salt or neutral salt. Acidic salts have the pH lower than 7. They are formed by reaction between strong acid and weak base. Basic Salts have pH higher than 7. They are formed by reaction between weak acid and strong base. Neutral salts have pH of 7. They are formed by the reaction between strong acid and strong base.

The tertiary sector is different from the other two sectors because the other sectors produce goods but this sector does not produce goods by itself. Instead, the tertiary sector activities help in the development of the primary and secondary sectors. These activities are an aid or support for the production process, e.g., transport, communication, storage, banking, insurance, trade activities etc. For this reason this sector is also known as service sector.

    let cost(in RS) of one pencil = x
             and cost (in RS) of one pen = y
Therefore , according to question
                      5x+7y = 50  ........ (1)
                     7x + 5y = 46  .........(2)
       Multiply equation 1 by 7 and equation by 5 we get
                         7(5x+7y)= 7*50
                         35x +49y = 350 .......(3)
                   and
                         5(7x +5y) = 5*46
                         35x +25y = 230 ....... (4)

Subtract equation 4 from equation 3 , we get
                            35x + 49y - 35x - 25y = 350 -230
                             49y -25y = 120
                             24y = 120
                                 y = 120 /24
                                 y= 5
Substitute y=5 in equation 1 , we get
                 5x +  7*5 =50
                 5x+35 =50
                 5x = 50 - 35
                 5x =15
                 x= 15/5
                 x=3

Hence Cost of One Pencil = x =3
           Cost  of One Pen =y =5

(i) Organs of the government: Legislature, executive and judiciary are the three organs of the government. Legislature is responsible for making laws, executive organ is responsible for execution or implementation the laws whereas judiciary is there to provide justice to the people or to solve the disputes.
(ii) Power sharing: In India the Union Parliament, i.e., the Lok Sabha and the Rajya Sabha makes laws whereas various ministers and government officials are responsible for the execution of the laws. These ministers are not independent but they are responsible or answerable to the Parliament or State Assemblies. Similarly, although judges are appointed by the executive, they can check the functioning of executive or laws made by the legislatures. This arrangement is called a system of checks and balances.

Endothermic Reactions

The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat. Few examples of endothermic process is photosynthesis, evaporating liquids, melting ice, dry ice, alkanes cracking, thermal decomposition, ammonium chloride in water and much more.

Exothermic Reactions

The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. Few examples are neutralization, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulfuric acid into water and much more.
