Although they don't have mass, photons-traveling at the speed of light-have momentum. Space travel experts have thought of capitalizing on this fact by constructing solar sails-large sheets of material that would work by reflecting photons. Since the momentum of the photon would be reversed, an impulse would be exerted on it by the solar sail, and-by Newton's Third Law-an impulse would also be exerted on the sail, providing a force. In space near the Earth, about 3.84·1021 photons are incident per square meter per second. On average, the momentum of each photon is 1.30·10-27 kg m/s. Assume that we have a 1483 kg spaceship starting from rest attached to a square sail 23.9 m wide.
a) How fast could the ship be moving after 59 days?
b) How many months would it take the ship to attain a speed of 8.19 km/s, roughly the speed of the space shuttle in orbit?
A sphere of aluminum 11.3 cm in diameter is suspended in oil (density = 1 grams/cm3). Find the tension in the supporting string in Newtons
A 70 ohm lamp and a 75 ohm lamp are connected in series and placed across a potential of 41 V. What is the equivalent resistance of the circuit
A driver wearing a seatbelt decelerates at roughly the similar rate as the car itself. Since modern cars have a "crumple zone" built into the front of the car, the car would decelerate over a distance of roughly 1.20 m. Determine net force acting ..
Two converging lenses are used in a particular device. The first lens (the one closest to the object) has a focal length of 200 mm. Find the distance of the final image along with its magnification
An electromagnetic wave in a vacuum has a magnetic field with a magnitude of 1.27 × 10-6 T. What is the intensity S of the wave
A new event has been proposed for the Winter Olympics. Anathlete will sprint 150 m, startingfrom rest, then leap onto a 19.9 kgbobsled. How far will Jennifer compress the spring
Find the critical angle of incidence for a ray of light going from a diamond to air
To estimate the muzzle speed of a blow dart, fire dart straight up into the air and time how long it takes to come back down. Roughly half of that time is the time for object to decelerate from its initial velocity to motionless. Estimation the in..
Write down the equation for this process, and using values for the binding energy of the hydrogen and carbon-12 nuclei of 0 MeV and -92.2 MeV respectively, calculate the binding energy of the nitrogen nucleus.
