The answer is A a change in time
Answer:
Economic activity is the activity of making, providing, purchasing, or selling goods or services.
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. so, the correct answer is option A.
<h3>What is the Rutherford experiment?</h3>
Rutherford performed an experiment in which alpha particles are bombarded on the gold foil.
Some of the particles bounced back which indicates that there are heavy particles present in the center of an atom.
Most alpha particles pass through the atom which indicates that there is a lot of empty space in an atom.
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. so, the correct answer is option A.

Answer: E) Acceleration, net force
Explanation: In order to explain this problem we have to consirer that the uniform circulat motion has constant angular velocity (ω) and the vector velocity is changed its direction for any point that cover the circle but its modulus is contant and its value is v=ω*R. In order to ensure these conditions, the net force also the accelaration called centripetal must point to the center of the circular trajectory.
1). the total voltage between the ends of the series circuit was constant.
The resistance of the circuit and the current through the circuit changed.
2). The voltage between the end terminals of the parallel circuit is constant.
The resistance of the circuit and the current through the circuit changed.
3). So that you can avoid building a circuit that needs more current
than your battery can supply, and also to be sure and choose a battery
or power supply that's able to deliver the amount of current that your
circuit needs.
