How many moles of helium would give a pressure of 900 mm Hg in 25.0 L vessel at
500C?
Write a complete Java program illustrating the difference between instance and static members of class. Indicate with comments where each is used and explain the significance of making the instance or static. (6 marks)
10.) A bullet is fired at an initial velocity of 150 m/s and an angle of 56° at the top of a 120 m tall building. Neglecting air resistance, determine the following:
a. The maximum height above the level ground that can be reached by the bullet.
b. The time for the bullet to hit the ground.
c. The velocity with which the bullet will hit the ground
If A'B + CD' = 0, then prove that:
AB + C'(A' + D') = AB + BD + (BD)' + A'C'D.
Making use of object orientation write a program that stores and evaluates the total cost for items bought from a supermarket. The cashier should enter the following: - Product code, Price and Quantity. The total price should be evaluated as follows: -
Total cost = Price * Quantity
If the total cost per item is more than 20,000 there is a discount of 14% on that item and a discount of 10% on an item whose total cost is between 10,000 and 20,000. No discount is given on items whose total cost is less than 10,000
7. ) A shot is project 40° from the horizontal at the rate of 30 ft/s. (a) Find the maximum height (b) the maximum range of projectile.
8. ) A drop hammer of 1 ton weight capacity is projected downward by a 12 inch diameter cylinder. At 100 psi air pressure, what is the impact velocity if the stroke is 28 inches.
9.) A projectile is fired up the inclined plane at an initial velocity of 15 m/s. The plane is making an angle of 30° from the horizontal. If the projectile was fired at 30° from the incline, compute the maximum height z measured perpendicular to the incline that is reached by the projectile. Neglect air resistance.
4. ) A stone is thrown vertically up from the ground with a velocity of 400 ft per sec. How long must one wait before dropping a second stone from the top of an 800ft tower if the two stones are to pass each other 300 ft from the top of the tower?
5.) It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s², determine the speed of the Jaguar before it began to skid.
6. ) A capsule orbit the earth at the rate of 6000 m/s. If the radius of the Earth is 3000km, find the height of capsule from the surface of the Earth.

1.) A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled.
2.) A feather is dropped on the moon from a height of 1.40 meters. The acceleration
of gravity on the moon is 1.67 m/s
2. Determine the time for the feather to fall to the surface of the moon.
3.) An engineer is designing the runway for an airport. Of the planes that will use the
airport, the lowest acceleration rate is likely to be 3 m/s². The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway?
