Answer:
Circular motion
Explanation:
Consider a car race, where you need to finish one lap in a circuit. Her the start line and the finish line are the same. So , where you start, is where you will be reaching after the race is done. So, the displacement here is <em>Zero</em> , since displacement is the distance from initial point to final point. But, as one can see, the distance travelled is not zero.
Say the race track is a circle of radius r meters. So the lap distance would be the circumference of the circle, which is 2πr m. So the distance travelled is 2πr m and the displacement is zero.
Hope this satisfies you :)
Answer:
+3
Explanation:
If an atom loses electrons, it becomes positive. Because silver loses 3 electrons, the charge becomes positive 3.
Answer:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.
