I am in 11 class and want to do law in future so I am in search for tuition. I am a weak student. Kindly suggest me some tips.

I am taking coaching in Chandigarh for IIT-JEE but not performing well. Should I take extra tuitions to catch up? If yes can you suggest some in Chandigarh?

Here are some examples: One's body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it. If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. Shaking a bottle of ketchup. When bringing the bottom down, the suddenly stopping it, inertia is what causes the ketchup to come out of the bottle. If one drove a car directly into a brick wall, the car would stop because of the force exerted upon it by the wall. However, the driver requires a force to stop his body from moving, such as a seatbelt, otherwise inertia will cause his body to continue moving at the original speed until his body is acted upon by some force. Hovercraft are vehicles that can be a challenge to manipulate because, unlike cars, they do not have the same level of friction, so inertia causes the Hovercraft to want to continue in its same direction without stopping or turning. Abruptly stopping a cart with an object on top causes the object on top to fall off. Inertia causes this by making the object want to continue moving in the direction that it was. If a stopped car is hit by a moving car from behind, the passengers inside may experience whiplash as a result of the body moving forward but the head lagging behind. The head is experiencing inertia. When a car is abruptly accelerated, drivers and passengers may feel as though their bodies are moving backward. In reality, inertia is making the body want to stay in place as the car moves forward. If an index card is placed on top of a glass with a penny on top of it, the index card can be quickly removed while the penny falls straight into the glass, as the penny is demonstrating inertia. If you jump from a car of bus that is moving, your body is still moving in the direction of the vehicle. When your feet hit the ground, the grounds act on your feet and they stop moving. You will fall because the upper part of your body didn’t stop and you will fall in the direction you were moving. When you stir coffee or tea and stop, the swirling motion continues due to inertia.

Hell-Volhard-Zelinsky Reaction is an organic reaction that involves the halogenation of carboxylic acid at the ??-carbon atom of the carboxylic group.In this reaction, when bromine is treated with catalytic amount of phosphorus leads to selective ??-bromination of carboxylic acid. This reaction is carried out in the absence of halogen carrier. This is because, Hell-Volhard-Zelinsky Reaction is carried forward by catalytic amount of PBr3.
