Near the surface of Earth, an electric field points radially downward and has a magnitude of approximately 100 N/C. 1)What charge (magnitude and sign) would have to be placed on a penny that has a mass of 3.11 g to cause it to rise into the air with an upward acceleration of 1.990 m/s2? (Express your answer to three significant figures.)

A leaky 10-kg bucket is lifted from the ground to a height of 13 m at a constant speed with a rope that weighs 0.6 kg/m. Initially the bucket contains 39 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 13-m level. How much work is done? (Use 9.8 m/s2 for g.) Show how to approximate the required work (in J) by a Riemann sum. (Let x be the height in meters above the ground. Enter xi* as xi.)

Answer each question below briefly, eg., in a sentence or two at most. a) pts) Assign an IP address to the leftmost interface of the router, given that the subnet part of IP addresses are 24 bits. b) (3 pts) Suppose A wants to send an IP datagram to B and knows B's IP address. Must A also know B's MAC address to send the datagram to B? If so, how does A get this info? If not, explain why not. c) pts) Suppose A wants to send an IP datagram to C and knows C's IP address. Must A also know C's MAC address to send the datagram to C? If so, how does A get this info? If not, explain why not d) (4 pts) Suppose that has a datagram that was originally sent by A) to send to C. What are the MAC addresses on the frame that is sent from R to c? What are the IP addresses in the IP datagram encapsulated within this frame? e) 4 pts) Suppose the switches above are learning switches and suppose that the switch has just been turned on Suppose now A send an Ethernet frame to B. a. On how many outgoing switch interfaces will this first frame be carried? b. Now suppose that B replies to A and A sends a second frame to B. On how many outgoing switch interfaces will this second frame be carried 1) pts) Suppose now that the router is removed from the scenario above. Can the nodes keep their IP addresses the same as shown in the picture above? Explain in one or two sentences.
