Hi Professor Navin! Could you please lower the price to $40 Please?


"I need answers on the following questions, please include formulas and explanation, so I'll know how to do it. I'll need it by tomorrow night, Thursday May 06/10


1) List Newton's three laws of motion. Explain in your own words what each one means.


2) If ice has a mass density of 0.92g/cm3, What is the volume of 5,000g of ice?


3) What is the mass of gasoline (p=0.680g/cm3) in a 94.6 L gasoline tank?


4) What is the momentum of a 30.0kg shell fired from a cannon with velocity of 500m/s?


5) What tension must a 50.0cm lenght of string support in order to whirl an attached 1,000g stone in a cicular path at 5.00m/s?


6) What is the kinetic energy of a 30.0g bullet that is traveling at 200.0 m/s?


7) Which pair of variables defines motion?


A- Speedd and distance
B- Time and momentum
C- Change of position and passage of time
D- Speed and passage of time


8) Which choice below pairs a scientific term with the correct scientific unit?


A- Work: Newton
B- Power: Joule
C- Force: Joule
D- Power: Watt


9) One of the following forms of energy can move through the vacuum of outer space without any involvement of matter.


A- Radiant
B- Mechanical
C- nuclear
D- Chemical


10) In order for an object to move in a circular path at a constant speed, which set of conditions must be satisfied?


A- A force must be applied once to start a circular motion, then the object wil continue in circular path.

B- A force must be applied continuously against the object's motion to cause it to turn away into a circular path.

C- A force must be applied continuously at right angels to the object's motion to produce a circular path.

D- No force need to be applied since speed remains constant.



On the other hand I need to submit the following questions in a form of an essay:

1- How does the study of heat relate to the kinetic theory of matter?


2- Wha is the relationship between heat and temperature? How are they different?


3- What are the various properties of a substance that determine its heat capacity?


4- What are the various sources of heat?
