So the question is asking for time.
Time= distance / speed
120/30
4
Therefore answer is d
The work output of a machine can be anything, depending on the friction
and other losses internal to the machine. But it can never be MORE than
the work <u>input</u>.
I suppose you might say that the work output can never be less than zero,
because there's no such thing as negative energy.
D. endothermic
Explanation:
Since the chemosynthesis reaction uses up heat and other inorganic compounds to produce food for themselves, the process is endothermic.
- In an endothermic reaction, heat is absorbed from the surrounding.
- The surround will then become colder at the end of the reaction.
- Since the chemosynthesis reaction uses up heat, it is an endothermic reaction.
- Exothermic reactions liberates heat to the surrounding.
- The surrounding becomes hotter at the end of the change.

Answer:
one electron
Explanation:
An atom with potassium has one electron in its outer energy level. This isn't a sturdy outer energy level. Keep in mind that, with majority of the elements a stable outer energy level has 8 electrons. When it blends with iodine, potassium loses an electron from level 4
