1. ## Mole conversions

I have question regarding moles conversion. What are the mole conversion formulas involving grams & formula units?
2. ## Help me to find out Density problem.

Thank you AshBox. I find the perfect solution.
3. ## Help me to find out Density problem.

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.
4. ## How Do I Find This? [Physics question]

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.
5. ## Entropy & Time

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.
6. ## How Do I Find This? [Physics question]

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.
7. ## Kinematics Physics Question

Thank You AshBox, This will help me.
8. ## Plimsoll lines - Question

Thank you so much for guide me.
9. ## Kinematics Physics Question

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?
10. ## Help me with this Geometry Question

Thanks for easy solution Mr. michel123456
11. ## Plimsoll lines - Question

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.
