Adriver who does not wear a seatbelt continues to move forward with a speed of 18.0 m/s (due to inertia) until something solid like the steering wheel is encountered. the driver now comes to rest in a much shorter distance-perhaps only a few centimeters. find the magnitude of the net force acting on a 65.0 kg driver who is decelerated from 18.0 m/s to rest in 5.00 cm. a driver who does not wear a seatbelt continues to move forward with a speed of 18.0 (due to inertia) until something solid like the steering wheel is encountered. the driver now comes to rest in a much shorter distance-perhaps only a few centimeters. find the magnitude of the net force acting on a 65.0 driver who is decelerated from 18.0 to rest in 5.00 . f=3240n f=1.173×104n f=2.113×105n f=4.213×105n

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
