I hope the wire is not wound too tightly around the bar magnet.
The device will generate electrical energy when the bar magnet
is moving in or out of the coil of wire.
Answer:
D) 4.9 m/s
Explanation:
Speed of Object in Free Fall
s = Rate of Acceleration, Due to Gravity × Length of Time
s = 9.8 × 2.0
s = m/s (Round Up to The Nearest Whole Number)
--
m/s = 9.8 ÷ 2.0 = 4.9 m/s
Answer: Well that is a good question and the answer is that wind energy is motion which is kinetic energy since its a renewable energy source.
Hope it helps
How does physical weathering compare to natural erosion?Physical weathering is the breakdown of rocks and soil, while natural erosion is the removal of solids (sediment, soil, rock) and occurs with movement. Eosion differs from weathering because it is transferred by wind, water, and ice; gravity has an immense role in erosion; and even living organisms are a key <span>component to erosion because certain species burrow, which disturbs the soil. </span>
