Ahigh-flying spy-plane must take pictures of the ground with the ability to resolve some objects down to 3.33 cm in size. u-a plane with cruising altitude of 70,000 feet. 13. assuming an average wavelength of 580 nm, what is the smallest aperture diameter of the objective lens necessary to resolve the minimum sized object? if this diameter is the size made by f-stop number 8, what is the power of the primary objective? what is the distance between the lens and the ccd (the "film")? what is the magnification of the lens? what is the imaged size of the minimum sized object? if the ccd has a pixel density of 3600 pixels/cm, how many pixels are needed to image the minimum sized object? d - if ccd is a square of 25 mm in length per side, how many total pixels are there in the ccd and how large an object area can be covered by just one image?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Could someone . i have tried to solve myself but my calculation is off
