Question 1 (5 points)

Students learned that objects can exert forces on other objects without

touching.

Which three investigations will provide evidence to support what they have learned

Answer 1

Electricity, gravity of earth and structure of atom provide evidence.

Step-by-step explanation:

The investigation of electricity, gravity of earth and structure of atom helps the student to understand that without touching, one object apply force on another object. In electric current, we can see the property of magnetism due to which it attract and repel objects while in gravity of earth, the earth apply gravitational force to attract objects towards itself. in the structure of atom, proton present in the nucleus which attract the electron present in the shells.
