Question

question 5
what geophysical tool is best at detecting objects with large (or small) masses?
gravimeters
magnetometers
earthquake waves
thermometers
question 6
which would a scientist have more confidence in?
a hypothesis they have about something

Explanation:

Question 5

Gravimeters measure gravitational fields, which are affected by mass. Magnetometers detect magnetic fields (not directly related to mass), earthquake waves study seismic activity, and thermometers measure temperature. So gravimeters are best for detecting mass - related objects.

In science, a hypothesis is a tentative explanation, while a theory is a well - substantiated explanation that has been repeatedly tested and confirmed. So a scientist would have more confidence in a theory (assuming the other option is a hypothesis as per common question structures).

Answer:

A. Gravimeters

Question 6

(Note: Since the options for Question 6 are not fully visible, assuming a common scientific context where a theory (well - tested, with evidence) is more trusted than a hypothesis (a tentative explanation). If the full options were like "A hypothesis they have about something" and "A theory that has been repeatedly tested and supported by evidence", the answer would be the theory. But with the current partial view, if we assume the typical case where a theory is more reliable than a hypothesis):
