Answer :
Explanation :
A Contact force is a force applied to a body by another body that is in contact with it. Contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. Contact force is governed by Newton’s Laws. Examples :: Contact force is responsible for most of the interactions we experience in the daily life. 1. Writing your name with a pen, pushing a car up a hill, lifting an object, etc... 2. Kicking a ball, hammering a nail, etc... are some of the everyday examples where contact forces are at work. In the first case, the force is continuously applied by the person on the car or pen or an object while in the second case the force is delivered in a short impulse. Contact forces are often decomposed into orthogonal components one perpendicular to the surface in contact called the normal force, and one parallel to the surface in contact, called the friction force.

Answer :
Explanation :
We can make an equation: 3(100000 + x) = 10x+1 (Why? Well, adding 100000 puts a 1 at the front of a five-digit number, and multiplying by 10 and adding 1 puts a 1 at the end of a number) Solving this gives: 10x+1 = 3(100000 + x) 10x+1 = 300000 + 3x 10x = 299999 + 3x7x = 299999x = 299999/7 = 42857 The answer is 42857 (142857 is three times smaller than 428571).

Answer : 2. "4 yrs"
Explanation :
Answer: B) 4 yrs Explanation: Let the present age of Deepa = 5p Let the present age of Hyma = 6p After four years their ratio = 6 : 7 => 5p + 46p + 4 = 67 => 35p + 28 = 36p + 24 => p = 4 Therefore, the difference between their ages = 24 - 20 = 4 years.
