Answer:
Lo sé bien, siempre me preguntaría eso .-.
Explanation:
D. Acceleration describes how the velocity changes in time.
Answer:
Gravitational energy and kinetic energy
Answer:
metre per seconds
Explanation:
because velocity = distance ÷ time
-- The unit of frequency is "per second" (Hz), which is [reciprocal time].
-- The unit of period is "second", which is [time].
Do you see where this is going ?
'Frequency' and 'period' are reciprocals of each other.
For any wave ...
Period = (1) / (frequency) .
Frequency = (1) / (period) .
