R= (rou * L) / area
where R is the wire resistance
rou: resistivity of the wire material
L : wire length
A : cross section area of wire
by sub.
0.757= (rou*25)/ 3.5*10^-6
25*rou = 2.6495*10^-6
rou= 1.0598*10^-7 ohm.m
Is it is the source of potential energy in a circuit. into electric potential energy? Chemical energy is transformed into electric potential energy.
When you push a door closed it doesn't travel in a straight line it turns around the hinges this is an example of a line
There is no (gap) in time between the action and the reaction
hope that helps:)
Answer:
Kinetic energy of the system = 2547.41 Joules.
Explanation:
Given:
Disk:
Mass of the disk (m) = kg
Radius of the disk (r) = cm = m
Cylinder:
Mass of the annular cylinder (M) = kg
Inner radius of the cylinder = m
Outer radius of the cylinder = m
The angular speed of the system = rev/s
Angular speed in in terms of Rad/sec = rad/sec
Formula to be used:
Rotational Kinetic energy, =
So, before that we have to work with the moment of inertia (MOI) of the system.
⇒ MOI of the system = MOI of the disk + MOI of the cylinder
⇒ MOI (system) =
⇒ MOI (system) =
⇒ MOI (system) = kg.m^2
Now
The rotational Kinetic energy.
⇒
Plugging the values.
⇒
⇒ Joules
Then
The kinetic energy of the rotational system is 2547.41 J.
