Secret agent Samantha Bond, 48.50 kg, has just ignited her jet powered skis at the foot of a 10.0 degree slope that rises in height by 50.0 m. The skis have a thrust of 244.0 N. When she gets to the top of the slope, she keeps the skis at 10.0 degrees as she flies through the air. At what horizontal distance from the top of the slope, from where she took off, will she land? This will be 50.0 m below where she took off. The thrust of the skis is parallel to the skis. There is no friction on the slope, and air resistance can be ignored.

a. A camera has a lens with a focal length of 0.032 m. The camera is set to an f-number of 5.6. The shutter speed (the amount of time during which the aperture is open to expose the film) is set to 0.35 s. What is the diameter of the camera's aperture?

b. If the camera is focused on an object that is 0.39 m away from the lens, how far is the film behind the lens?

c. If the f-number is changed to 2.8, does that increase the amount of light hitting the film, decrease it, or leave it unchanged?
Increases it.
Does not change it.
Decreases it.

d. By what factor does the amount of light hitting the film change when the f-number is changed from 5.6 to 2.8?

e. If you wanted to adjust the shutter speed so that the amount of light falling on the film with an f-number of 2.8 was the same as it was for the original f-number and shutter speed, what shutter speed should you use?

f. If you want to focus the camera on a very distant object, how far must the lens be from the film?

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate as for the first pipe?

1) Serious bicyclists say that if you reduce the weight of a bike, it is better to reduce it in the wheels rather than in the frame. Why would reducing weight in the wheels make it easier on the bicyclist than reducing the same amount on the frame? 2) Why is a tapered water glass with a narrow base easier to tip over than a glass with straight sides? Does it matter if the glass is full or empty? 3) Using Bernoulli’s theorem, explain how a plane can take off.

What is the purpose of having fuses or circuit breakers in electric circuits? How should they be connected in circuits so they will be effective?

A test rocket is launched, starting on the ground, from rest, by accelerating it along an incline with constant acceleration "a". The incline has length "L", and it rises at ? degrees above the horizontal. At the instant the rocket leaves the incline, its engines turn off and it is subject only to gravity, g?+9.81m/s2.  (Air resistance can be ignored). Taking the usual x-y coordinate system, with an origin at the top edge of the incline,  (a)what is the position vector when the rocket is at its highest point?  (b)What is the position vector when the rocket is on its way back down and once again at the same height as the top edge of the incline?  Your symbolic answer should only depend on a, L,?, g, and/or numerical factors Asked by

At the end of most landing runways in airports, an extension of the runway is constructed using a special substance called formcrete. Formcrete can support the weight of cars, but crumbles under the weight of airplanes to slow them down if they run off the end of a runwa

What is the maximum angle of climb (steady velocity climb) for a turbojet powered aircraft with an (L?D)max equal to 10.5 and a gross weight of 8000 lb. if it is producing a thrust of 2000 lb.?
