Explanation:
From the question we are told that
The radius of the spherical balloon is
The mass of the balloon is
The volume of the spherical balloon is mathematically represented as
substituting values
The total mass the balloon can lift is mathematically represented as
where is the density of helium with a value of
and is the density of air with a value of
substituting values
Now the mass of the cargo is mathematically evaluated as
Answer:
If there is no damping, the amount of transmitted vibration that the microscope experienced is =
Explanation:
The motion of the ceiling is y = Y sinωt
y = 0.05 sin (2 π × 2) t
y = 0.05 sin 4 π t
K = 25 lb/ft × 4 sorings
K = 100 lb/ft
Amplitude of the microscope
where;
=
= 4.0124
replacing them into the above equation and making X the subject of the formula:
Therefore; If there is no damping, the amount of transmitted vibration that the microscope experienced is =
