Frequency = (wave speed) / (wavelength)
Frequency = (24 m/s) / (2 m)
Frequency = 12 per second .
Where is that space to put the answer into ?
The calculation of the centripetal acceleration of an object following a circular path is based on the equation,
a = v² / r
where a is the acceleration, v is the velocity, and r is the radius.
Substituting the known values from the given above,
4.4 m/s² = (15 m/s)² / r
The value of r from the equation is 51.14 m.
Answer: 51.14 m
Answer:
90 ohms
Explanation:
1/r = 1/180 + 1/180
1/r= 2/180
take the reciprocal of 2/180 which is 180/2 and its 90 ohms
The sun will most likely illuminate Earth equally on both
poles during September and March. On these months, Earth will not be tilted
toward or away from the sun. This results to both poles receiving nearly the
same amount of light, which means that the length of days and nights are equal
all over Earth. This event is referred to as Equinoxes. During March, it is
called the Vernal Equinox, while during September, it is called the Autumnal
Equinox.
