Answer:
A. Sliding friction
Explanation:
Sliding friction is weaker than static friction
Wave speed = (wavelength) x (frequency)
We know the wavelength, but we don't know the frequency. How can we find the frequency ? "Here frequency frequency."
We know the period, and frequency is just (1 / period). So . . .
Wave speed = (wavelength) / (period)
Wave speed = (2.1 meters) / (9.4 seconds)
Wave speed = (2.1 / 9.4) m/s
<em>Wave speed = 0.223 m/s</em>
The hypothesis would be can professional swimmer hold their breath longer than people who aren't
Answer:
see below
Explanation:
there is a trick to this kind of questions,
you look at the units, the one which looks way too complicated
the
D = 24 g/mL
so it means that
24 = g/ mL
so sub in Values = 1.2 mL
24 = g / 1.2
24 x 1.2 = g
28.8 = g
but since you want mass and mass is in kg
mass = 0.0288 kg
hope this helps ,please mark it brainliest
