You need to provide connectivity between two buildings without running any cables. You decide to use two 802.11ac APs to provide wireless connectivity between the buildings. Which of the following is the BEST choice to support this need?a. Use omnidirectional antennas on both APs.
b. Use wide channels.
c. Use the 2.4 GHz frequency band.
d. Use direction antennas on both APs.

Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. the electric field at a point p, which is 0.50 m from the center of the sphere, is 15,000 n/c and is directed radially outward. what is the maximum magnitude of the electric field due to this sphere

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
