In 2000, NASA placed a satellite in orbit around an asteroid. Consider a spherical asteroid with a mass of 5.00�1015kg and a rad
irakobra [83]

Answer:

a).v_{1}=13.49 \frac{m}{s}

b).v_{2}=17.54\frac{m}{s}

Explanation:

Using the conservation of energy and the kinetic energy of the satellite around the asteroid can model the motion in

\frac{1}{2}*m*v^2=\frac{G*M*m}{a_{o}}

v^2=\frac{2*G*M*m}{a_{o}}

G=6.673x10^{-11}\frac{m^3}{kg*s^2}

M=1.20x10^{16}kg

a).

a_{o}=8.8km*\frac{1000m}{1km}=8800m

v=\sqrt{\frac{2*6.673x10^{-11}\frac{m^3}{kg*s^2}*1.2x10^{10}kg}{8800m}}

v_{1}=13.49 \frac{m}{s}

b).

a_{f}=5.2km*\frac{1000m}{1km}=5200m

v=\sqrt{\frac{2*6.673x10^{-11}\frac{m^3}{kg*s^2}*1.2x10^{10}kg}{5200m}}

v_{2}=17.54\frac{m}{s}

Sopranos can sing notes at very high frequencies—over 1000 Hz. When they sing such high notes, it can be difficult to understand
STALIN [3.7K]

Answer: High frequency= High harmonics= Different formants

Explanation:

We are given that sopranos can sing notes at very high frequencies.

Now, when they sing high notes it is difficult to understand their words.

According to the  concept of harmonics, it is the integer multiple of the fundamental frequency. And formants are the different frequencies which in turn give us different vocalizations.

Now, the frequency is over 1000 Hz this implies that the harmonics will be greater and in turn formants will be different. So, this is the reason it is difficult to understand the words of sopranos when they are singing at very high frequencies.
