centripetal force is given as
F = m r w2
the value of angular speed "w" is same at all locations and mass "m" is also same
hence force depends on distance "r" from center. since at edge "r" is maximum , hence the centripetal force is maximum at edge
c. edge

a)
W = work done = change in kinetic energy
25.
T = time period = 0.072 sec
w = angular speed = 2/T = 2 x 3.14/0.072 = 87.22 rad/s
r = radius = 0.29 m
speed is given as
v = r w = 0.29 x 87.22 = 24 m/s
24.
given that :
gjupiter = 3 gearth
multiplying both side by mass "m"
mgjupiter = 3 mgearth
Wjupiter = 3 Wearth
b) more than

PLEASE HELP ME WITH MY PHYSICS 133. THANK YOU. 4) Which statement is true about Lenz's Law? A) It can be demonstrated using conservation of energy. C) You need to know all of the electrostatic charge contained in the Lenz Surface. The direction of the induced magnetic field is always parallel with the flux It is a violation of the space time symmetry in 5 dimensions.
