Q:

What is a Contact Force and explain with an example?

Answer

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.

Q:

5/8 as a Decimal Equals To

A) 0.625 B) 0.541
C) 0.258 D) 0.147
 
Answer & Explanation Answer: A) 0.625

Explanation:

5/8 is Nothing but to divide 5 into 8 parts.

 

 

As 5 is smaller than 8, the quotient starts with a decimal point to make 5 as 50 to be divisible by 8. (0.)

 

 

Now 50 goes for 6 times in 8 leaving a remainder 2. (0.6)

 

  

Again 2 is smaller than 8, As it already has decimal point in the quotient, now 2 becomes 20.

 

  

Now 20 goes for 2 times in 8 leaving a remainder 4. (0.62)

 

  

Again 4 is smaller than 8, As it already has decimal point in the quotient, now 4 becomes 40.

 

 

Now 40 goes for 5 times in 8 leaving a remainder 0. (0.625)

 

 

Therefore, the decimal value of 58 is 0.625.

 

Now find a decimal value of 1117 and Discuss your at Discuss.
