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:

What is the term used in tennis when the score is 40-40?

A) Ace B) Led
C) Deuce D) Tie
 
Answer & Explanation Answer: C) Deuce

Explanation:

When both sides have won the same number of points then: when each side has won one, or two, points, the score is described as "15-all" and "30-all" (or "15-up" and "30-up"), respectively.

However, if each player has won three points, the score is called as "deuce", not "40–all". From that point on in the game, whenever the score is tied, it is described as "deuce", regardless of how many points have been played.

Q:

How fast do satellites orbit the earth?

A) 28,000 kmph B) 26,000 kmph
C) 17,500 kmph D) 22,500 kmph
 
Answer & Explanation Answer: A) 28,000 kmph

Explanation:

Satellites orbit the earth at a speed of 28,000 kmph.

Satellites that are further away actually travel slower. The International Space Station has a Low Earth Orbit, about 400 kilometers (250 miles) above the earth's surface. Objects orbiting at that altitude travel about 28,000 kilometers per hour (17,500 miles per hour).

a. The evaluation system of XII Std. terminal examination should be made more tough so that fewer students pass the examination.
b. The Government should encourage the private sector to open new colleges by providing them land at cheaper rate.
c. The rich people should be asked to send their wards to foreign countries for higher studies enabling the needy students to get admission in colleges within the country.

A) only a and b follows B) Only c follows
C) Only b follows D) All a, b & c follows
 
Answer & Explanation Answer: C) Only b follows

Explanation:

Clearly, reducing the number of aspirants for admission to colleges or sending the students of well-to-do families to foreign countries for higher studies, is no proper solution. So, both I and III do not follow. The right solution is to increase the number of colleges so as t accommodate the increasing number of admission-seekers. So, only II follows.
