A spherical ball of radius 3 in is dropped into a conical vessel
of depth 8 in and radius of base 6 in. what is the area of the
portion of the sphere which lies above the circle of contact with
the cone?
A conical tank, point down, has a radius of 6 feet and a depth
of 9 feet. Water is filling the tank and thus the volume of water
in the tank is changing with time, as is the depth of the water and
the radius of the surface of the water. Suppose that at the instant
the depth of the water is 4 feet, the depth of the water is
changing at an instantaneous rate of0.125 feet per minute. How...
A solid spherical ball of radius 4 meters has a charge of 8
nC.
a) Calculate the electric potential at r = 2, r = 4, and r = 6
meters away from the center of the ball if it is a conducting
sphere.
b) Calculate the same things if it is an insulating sphere of
uniform charge density.
c) Calculate the same things if it is an insulating sphere of
non-uniform charge density, ρ = kr2

A thick spherical pressure vessel of inner radius 150
mm is subjected to maximum an internal pressure of 80 MPa.
Calculate its wall thickness based upon the (a) principal stress
theory, and (b) total strain energy theory. Poisson's ratio = 0-30,
yield strength 300 MPa.
please answer only if you know correctly.
A spherical bowling ball with mass m = 3.3 kg and radius R =
0.11 m is thrown down the lane with an initial speed of v = 8.9
m/s. The coefficient of kinetic friction between the sliding ball
and the ground is ? = 0.28. Once the ball begins to roll without
slipping it moves with a constant velocity down the lane.
What is the magnitude of the angular acceleration of the bowling
ball as it slides down the...
A
spherical ball of charge has radius R and
total charge Q. The electric field strength inside the ball (r?R)
is E(r)=
Emax=(r4/R4)
A) What is
Emax in terms of Q and R? Express your
answer in terms of the variables Q, R, and appropriate
constants.
B) Find
an expression for the volume charge density ?(r) inside the ball as
a function of r. Express your answer in terms of
the variables Q, r, R, and appropriate constants.
There is a solid, spherical dielectric (radius = 3 m) with a
total charge of 30 μC and with uniform charge density. What is the
