Server X is running Diablo II services on port #4000. Client A is running an application that uses port #450 to request an Diablo II TCP connection to Server X. Client B is running an application that uses port #455 to request an Diablo II TCP connection to Server X. IP addresses: Server X: 152.111.20.36 Client A: 113.13.131.10 Client B: 114.192.111.23 Client A starts a second application (running at the same time as the first application) that uses the next incremental port number to request an Diablo II TCP connection to Server X. The connection created for Client A is identified by the sockets at the endpoints as follows: IP address and port socket identifier Destination IP Address Destination Port Number On Client A 152.111.20.36 [ Select ] 114.192.111.23 455 152.111.20.36 456 113.13.131.10 4000 451 450 On Server X [ Select ] 114.192.111.23 113.13.131.10 4000 450 152.111.20.36 455 456 451 [ Select ] 4000 455 450 451 113.13.131.10 152.111.20.36 456 114.192.111.23多重下拉选择题

A 62.9 kg lady is standing on a weighing scale in an elevator as shown in the diagram below. Assume gravitational acceleration = 15 ms-2 Given that the elevator is accelerating upwards at 3.7 ms-2 , determine the magnitude of the normal force on the lady.
An object is fired from ground level at an angle of 31.9 degrees to the horizontal. Taking acceleration due to gravity = 7.65 ms-2 If the initial speed is 5.6 ms-1, how far from the starting point will it hit the ground? Assume air resistance is negligible.
