Answer: frequency = 523.2 Hz
Explanation:
One octave higher = 2f of the last octave.
For instance, if C2 = 4 Hz
A octave higher will be C3 in which its frequency will be 2 × 4Hz = 8Hz
Back to the question.
One octave higher frequency will therefore equal to:
2f = 2 × 261.6 = 523.2 Hz
Answer: The relationship between the pressure and the volume is given as P=K/V or PV= K. (Pressure increases as Volume decreases).
Explanation:
When gas is trapped in an enclosed medium for example a cylinder by a piston. When the piston is pushed in, the gas particles will have less room to move as the VOLUME the gas occupies has been DECREASED. This will automatically lead to frequent collision of the has particles with the wall of the container. The collision exerts forces which leads to INCREASED PRESSURE.
This obeys the Boyle's law which states that the volume occupied by a fixed mass of gas is inversely proportional to the pressure, provided temperature is kept constant. This can be mathematically expressed below:
PV=K, where K is constant
P1 V1=P2 V2
Where,
P1= initial pressure
V1= initial Volume
P2= final pressure
V2= final Volume.
Therefore, increasing pressure from initial pressure to final pressure means that initial volume will change to final volume, providing the temperature remains constant.
Magnetic fields surround magnets. They attract or repel, depending on the charge of the object in it.
Recall that the magnitude of the acceleration 
of a particle moving with speed 
in a circular path around a point at a distance 
away from the particle is given by
So, the satellite has velocity
pointing in the direction tangent to the circular path.
The answer is:
Transverse dune
The explanation:
Transverse dune : is abundant barchan dunes It may merge into barchanoid ridges, which then grade into linear .
The transverse dunes is called that because they lie transverse, or across, the wind direction, with the wind blowing perpendicular to the ridge crest.
It is large, very asymmetrical, elongated dune lying at right angles 90° to the prevailing wind direction.
Transverse dunes have a gently sloping windward side and a steeply sloping leeward side.
They general form in areas of sparse vegetation and abundant sand are transverse dunes.
