Answer:
0.0166 mm
Explanation:
Solution:-
- We are given a hollow palladium of material density ( ρpd ).
- The object is given to be spherical in shape with shell thickness ( t ).
- The radius of the spherical shell was determined in the first part ( R = 59.90 mm ).
- We are to determine the thickness of the shell wall.
- We will use the simple mass - density - volume relationship as follows:
m = ρpd*V
Where,
V: The volume of spherical shell
m: The mass of the object = 0.9020 kg
- The volume ( V ) of the hollow sphere can be written down in differential form as follows:
dV = As.dt
Where,
The thickness of shell ( t ) is uniform; hence,
V = As.dt
Where,
As = the surface area of sphere with median radius ( R )
- Therefore the formulation becomes:
m = ρpd*As*t
t = [ m / 4*ρpd*π*R^2 ]
t = [ 0.902 / (4*1.202*10^4*π*0.599^2) ]
t = 0.0166 mm ... Answer

Explanation:
Given
mass of boat
mass of Person
Length of boat
Center of mass of boat and child
when child reaches another end of boat, boat is shifted by x cm
Center of mass of the system will remain the same
Equating 1 and 2 we get
Electrical signals in the human body control breathing, heart beat, and muscle movement. If you receive an electric current from an outside source, it can result in a shock that interferes with your bodies electrical signals.
The last choice ... Experimental value -- <span>Accepted value ... is the place
to start, but it doesn't quite get you there.
To find the FRACTIONAL error, you'd have to divide that difference
by the Accepted Value.
And then . . .
To find the PERCENTAGE error, you'd have to multiply
the fractional error by 100 .

I think is altitude because tbh it don’t even mean nothing
