A type of anchor that is a good choice when jacking or leveling the fastening component is a stud bolt anchor.
<h3>What is a Stud bolt anchor?</h3>
These are the type of anchor which bare embedded in concrete with the threaded portion on the outside.
This makes it easier to jack or level the fastening component which is why option B was chosen.

Answer:
T = 5.45 10⁻¹⁰
Explanation:
Let's use Newton's second law
F = ma
force is the universal force of attraction and acceleration is centripetal
G m M / r² = m v² / r
G M / r = v²
as the orbit is circular, the speed of the satellite is constant, so we can use the kinematic relations of uniform motion
v = d / T
the length of a circle is
d = 2π r
we substitute
G M / r = 4π² r² / T²
T² =
the distance r is measured from the center of the Earth (Re), therefore
r = Re + h
where h is the height from the planet's surface
let's calculate
T² = (Re + h) ³
T =
T = 5.45 10⁻¹⁰
The greek letter λ (lamda) is used to represent the wavelength of the wave.
