You've given the answer, right there in your question.
The "magnitude of gravity" is described in terms of the acceleration
due to it, and you just told us what that is.
We can also notice that the figure you gave is about 0.66 of the
acceleration due to gravity on the Earth's surface. That tells us that
the distance from the Earth's center at that height is about
(1 / √0.66) = 1.23 times
the Earth's radius, so the height is about 910 miles above the surface.
Answer:
<h2>109.52 Hz</h2>
Explanation:
The frequency of the wave when given it's velocity and wavelength only can be found by using the formula
where
c is the velocity of the wave in m/s
is the wavelength in meters
From the question we have
c = 230 m/s
= 2.1 m
We have the final answer as
<h3>109.52 Hz</h3>
Hope this helps you
Answer:
D
Explanation:
From the information given:
The angular speed for the block 
Disk radius (r) = 0.2 m
The block Initial velocity is:
Change in the block's angular speed is:
However, on the disk, moment of inertIa is:
The time t = 10s
∴
Frictional torques by the wall on the disk is:
Finally, the frictional force is calculated as:
Explanation:
Chemical bonding results from attractive forces that joins chemical species.
- Noble gases show no tendency to combine with themselves or with other kinds of atoms because of their completely filled outer energy levels.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels just like the inert gases.
- The stable configuration can be attained by losing or gaining of electrons or sharing of pairs of electrons.
Two examples of how bonds form:
Bonds can be formed by:
- Losing and gaining of electrons to form electrovalent or ionic bonds.
- Sharing of electrons to form covalent bonds.
