False, the object will weigh less because gravity is weaker on the moon.
Answer:
26 cm
Explanation:
V = Volume
R = Outer radius of the shell = 58.7 cm
r = Inner radius of the shell
g = Acceleration due to gravity = 9.81 m/s²
\rho = Density
As the shell is completely submerged
Force on shell
Weight of the shell
Equating the two equations as the forces are conserved
Inner radius of the shell is 0.561 m
The thickness of the wall is 0.587-0.561 = 0.026 m = 26 cm
With enough strength it can more than likely get ripped out. Most weaves are not secure on a persons hair, therefore with some strength it can be pulled off. But of-course the person wearing it will suffer damage
force=mass x acceleration
acceleration= velocity/time
given that m=2300kg
v = 15m/s
t = 0.54s
f= 2300 x 15/0.54
f =2300×27.777
f=63888.89
Answer:
D. It is upright.
Because convex mirror produce the real image, and the plane mirror produce it's upright.
