Here, Take both LHS and RHS When you take LHS, LHS = (cot a. Cos a) / (cot a+ cos a) Put cot a = cos a / sin a and simplify. You will get (1 - sin a)/ cos a When you take RHS, RHS = (cot a - cos a) / (cot a .....
You might have learnt about density and buoyancy, which determine whether objects will sink or float in water. If an object’s density is greater than water, it will sink. Conversely, if an object’s density is less than water, it will .....
To float he just need to breath in deeply and to sink he just need to breath out deeply, this is the reason why first person sinks in water as he breath in deeply and after sometime he breathe out deepely and floats on water. Dead .....

There is a force called upthrust, which occurs in water. Everything is affected by upthrust when it is diped in water. You can also measure upthrust. If an object's weight is greater than its upthrust, then it won't float and will sink to .....
A ship can carry more load than an aeroplane because aeroplane engines main purpose is to fly the load whereas ships engine main purpose is to push the load. So if there is more weight on aircraft it is very difficult to fly but ships can carry .....
