Hi everyone. I am doing a physic’s project about Newton’s law of cooling. This project was basically to evaluate the change in temperature between a cup of cooling water and the room temperature as a function of time by using different methods of heat retention (via convection & evaporation...

Is there a way to do work this problem without calculus? Because my class is an algebra/trig based class. Thank you for your help.

specific heat? Hey guys….I need help with another problem. Q: Below are two sets of data from an experiment to determine the specific heat of a metal sample. For which mass will t the uncertainty n the specific heat be greater? Explain your answer. The uncertainty in all temperature...

Thanks...that make since to me.

Hi everyone….I have a new question. I am writing a lab write-up and I am kind of confused about a concept. In this lab I studied the even flow of water by analyzing the flow of water through a Bernoulli’s pipe. The pipe was set up in a way that it was vertical, open at the top (where a hose...

Perplexed again! I have two problems that I am stuck on...I don’t even know if I am going about these correctly. 1. A fountain consists of water jets mounted so that their nozzles are 2 ft above a pool. Each jet squirts water out at a 45o angle. The water lands in the pool approximately...

Thank you...that really helped.

I am stuck on this problem... A rowboat measures 4ft wide by 10ft long. How much (in inches) will the boat sink into the water when two 200 lbs me get into the boat? A: I am having a hard time getting the volume of the boat…does anyone have a suggestion? This was my plan: W boat=...

Thank you both! I really appreciate the help.

First off, I would like to thank HallsoIvy and Loren Booda for answering my last question. I really appreciate the help! However, I am really confused again. I have two problems that I need help with. Q: 1. trailer measures 9 feet tall (ground-to-top) and 6 feet wide. It weighs 5 tons...

Hi everyone…it feels like it has been a while but I have another question? This is dealing with vectors. Q: A boater wants to cross a river that has a current of 5mph and measures .75 miles in width. If the boat can travel at 20mph through the water, what heading must it take in order to...

Newton 2 law F = ma F = I* alpha

Hi everyone this is hopefully a quick and easy question: If a person spins an object that rotates, is that considered torque? When that object that is rotating, are the forces that act upon it: gravity, air resistance, friction, and the beginning twist from that person, Newton’s second law?

gnome, Thank you! That makes since to me and you made me laugh!
