Increasing ambient temperature decreases efficiency and load carrying capacity of electric transmission lines.
Increased molecular movement in the conductors as temperature rises, increases resistance to current flow.
Answer:
(a). The rotational inertia is 
(b). The magnitude of the magnetic torque is 
Explanation:
Given that,
Mass of neutron 
Density of neutron 
(a). We need to calculate the rotational inertia
Using formula of rotational inertia for sphere
...(I)
We know that,

Put the value of volume


Put the value of R in equation (I)

Put the value into the formula


The rotational inertia is
.
(b). We need to calculate the magnitude of the magnetic torque
Using formula of torque

Put the value into the formula


The magnitude of the magnetic torque is 
Hence, (a). The rotational inertia is 
(b). The magnitude of the magnetic torque is 
When only ________ acts on an object's mechanical energy is conserved.
<u>Answer</u><u>:</u>
Momentum
Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
