Answer:
m = 2,776.95 kg
Explanation:
given,
radius = 1.5 m
mass = 1.19 x 10⁴ Kg
constant speed, v = 1.4 m/s
Resistive force = 1105 N
density of sea water = 1.03 x 10³ kg/m³
Volume of vessel,
v = 14.14 m³
Upthrust,
U = ρ g V
U = 1030 x 9.8 x 14.14
U = 142729.16 N
Since the vessel is moving at a constant speed, the resultant force on it should equal zero.
downward acting forces = upward acting forces
Mg = U + resistive force
M x 9.8 = (142729.16+1105)
M=14676.95 Kg
Mass of water,
m = M - mass of vessel
m = 14676.95 Kg- 11,900 kg
m = 2,776.95 kg
Answer:2
Explanation:
Given
Cable has twice the length of cable B
and twice the radius(both inner and outer) of cable B
Inductance is given by
Where l=length
r=inner radius
R=outer radius
=Permeability of inner cylinder
suppose and
be the length of cable A and B
so
for wire B
divide 1 and 2 we get
