A resourceful physics student decides to build a device to lower him from his 3 story window safely. He begins with a heavy flywheel mounted on a frictionless axle which is attached to the roof. The flywheel has a diameter 82.0 cm He wraps a long rope around the outside of the flywheel and attaches a handle to the free end. Grabbing the free end he descends from rest a distance 7.00 m in a time of 6.10 s. If the mass of the physics student is 72.0 kg, what is the moment of inertia of the flywheel

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .
