  1. I have question regarding moles conversion. What are the mole conversion formulas involving grams & formula units?
  2. The density of two liquids (A and B) is given as 1000 kg/m3 and 600 kg/m3, respectively. The two liquids are mixed in a certain proportion and the density of the resulting liquid is 850 kg/m3. How much of liquid B (in grams) does 1 kg of the mixture contain? Assume the volume of the two liquids is additive when mixed.
  3. Thanks For the solution. Is there any online solutions available to find Acceleration unit conversions or force unit conversion tools? I am not from science student. I have to do some basic examples like this to help one of my friend.
  4. Hello everyone, Last day I had debate with my friend. She asked me this question: Does entropy increase with time ? Or Does it make Time? I have think on it but I couldn't answer it. Can anyone please help me to find this answer.
  5. If a ball is thrown upward at an angle of 30 with the horizontal and lands on the top edge of a building that is 20 meters away, the top edge is 5 meters above the throwing point, what is the initial speed of the ball in meters/second? Help me with initial steps.
  6. Can anyone help me to solve this? A lifeguard who can swim at 1.2 m/s in still water wants to reach a dock positioned perpendicularly directly across a 550 m wide river. a) If the current in the river is 0.80 m/s, how long will it take the lifeguard to reach the dock? b) If instead she had decided to swim in such a way that will allow her to cross the river in a minimum amount of time, where would she land relative to the dock?
  7. I have read about plimsoll lines, while loading a ship, care is taken it should not be overloaded. Its load depends on density of the see in which it floats. the ship will shink if its load exceeds. Now my question is how to indicate depth up to which a ship can shink? And at what density value? which ensures stabilty and safety of the ship.
  8. Hello all, I was practicing some problems and I come across this question : Is triangle ABC with sides a, b and c acute angled? Triangle with sides a2, b2, c2 has an area of 140 sq cms. Median AD to side BC is equal to altitude AE to side BC. Which one is the right answer? And How? Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked. BOTH statements (1) and (2) TOGETHER are sufficient but NEITHER statement ALONE is sufficient to answer the question asked. EACH statement ALONE is sufficient to answer the question asked. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked; additional data specific to the problem is needed.
  9. Thank you for great information. Thank You AshBox. I have tried this equation and it gave me exact result which I was wondering about.
  10. Hello, everyone This is my first forum. I need help to find the nth term of Fibonacci series with the golden ratio. Can anyone help me to know about golden ratio and its equation? and how to find Fibonacci series from it.
