Answer:
b) in a direction that makes its potential energy decrease.
Explanation:
- As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
- Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite to the change in electric potential energy, which will be always negative, independent of the sign of the charge.
Answer:
<h2>2,000 kg boulder</h2>
Explanation:t
The Inertial is the resistance of a body at rest to be in motion
Given the following item
1. 4kg shot put ball
2. 2,000 kg boulder
The body of greater mass has greater inertia, hence would be harder to accelerate.
<em> An object with a small inertial mass will accelerate more than an object with a large inertial mass when acted upon by the same force.</em>
Of the 2 items in the list, the 2,000 kg boulder has the largest mass, hence it also has the greater inertial and more difficult to accelerate.
