Energy is lost when machines don't work right. it is false because the law of conservation of energy states that energy can not be created or destroyed (lost)
Answer:
D. It uses boron so that electrical conduction is due to the movement of a positive charge.
Explanation:
Please mark me brainliest
<span>Using Newton’s 2nd
law, we can calculate for the force (F) required to give a mass 255kg an
acceleration of 3.5 m/s^2: </span><span>
F= ma</span>
<span>F= 255kg*3.5m/s^2 = 892.5 N </span>
892.5 was the force needed for the motorcycle alone. Taking
into account the total resistance of 400N:
total F = 892.5 N + 400 N
<span>total F= 1292.5 N</span>
They can be compounds too.
Examples: salt, sugar, and water are all compounds, not elements or mixtures.
