The answer is c capacitance
Answer:
it depends only on the forces acting along the y axis I think
Answer:
The final angular speed is 0.223 rad/s
Explanation:
By the conservation of angular moment:
ΔL=0
L₁=L₂
L₁ is the initial angular moment
L₂ is the final angular moment
L₁ is given by:

As the door is at rest its angular moment is zero and the angular moment of mud can be considered as a point object, then:

where
r is the distance from the support point to the axis of rotation (the mud hits at the center of the door; r=0.5 m)
v is the speed
m is the mass of the mud
L₂ is given by:

ωf is the final angular speed
The moment of inertia of the door can be considered as a rectangular plate:

M is the mass of the door
W is the width of the door
The moment of inertia of the mud is:

Hence,



Answer

Explanation:
given,
Side of square coil = 3.2 cm
Number of turns = 2720
magnetic field in the coil increases to = 0.45 T
time interval = 1.7 s
average induced voltage in the coil = ?
length = 0.032 m
Area = 0.032² = 0.001024 m²
induced voltage


The average voltage induced in the coil is equal to
