Final answer:
To locate a remote object named 't' at port 7000 on a host, you usually use a RMI lookup with the string pattern "//host:port/name".
Explanation:
To locate a remote object with a name t at port 7000 on the host, you would typically use a service lookup in a context such as Java's RMI (Remote Method Invocation) where you might use a specific lookup string in the RMI registry. The general pattern for this string would be "//host:port/name", where host is the name or IP address of the machine where the remote object is located, port is the port number where the object is listening, and name is the name of the remote object.
