Yes. In fact, a sentence must have a direct object in order to have an indirect object. (Note, however, that some consider the subject of a sentence in the passive voice to be an "implicit" indirect object, because it the sentence is changed to the active voice, the subject in the passive voice will often become an indirect object in the active voice.)
There is no indirect object; the direct object is 'it' (immediately is an adverb modifying the verb spent).
A direct or indirect object is a part of a sentence. A single word in isolation is neither a direct or indirect object. However, most nouns can be used in a sentence as either a direct or indirect object.
No, "grandmother" is not an indirect object. It is a noun that typically serves as a subject or direct object in a sentence. An indirect object is a noun or pronoun that receives the direct object. For example, in the sentence "She gave her grandmother a present," "grandmother" is the indirect object.
no
The direct object is "you"; the indirect object (I believe) is "this".
what is the indirect object
The indirect object is "her"; "the magazine" is the direct object.
The indirect object is 'you', as 'a cake' will always retain its function of direct object, no matter its position within the sentence.
Not exactly, but the subject of a passive sentence can be the indirect object of the equivalent active sentence--e.g. "Martha" in "Martha was given a rose by George" would be the indirect object in "George gave Martha a rose."
The indirect object is "hikers".
