Yes the winds are moving in a straight line
Answer:
<em>20cm</em>
Explanation:
<em>A coil wire comprises of 5 turns, it has a current of 2mA </em>
<em>A net magnetic field at the center of B is equal to Mu over 40 end fractions times T</em>
<em>The radius of a coil of wire with N turns is r = 0.28 m. A clockwise current of Icoil = 1.0 A flows in the coil,</em>
<em>Therefore 40/2mA = 20</em>
Answer:
T= 6.28fR²/µg
Explanation:
a=µg/R
(v-vi)/(t-ti)= µg/R
v: linear velocity of turntable at which coin begins to slip
vi: initial velocity
t: time at which coin begins to slide
ti: time at which turntable started moving
(v-0)/T=µg/R
T=Rv/µg
to find v,
v= wR
here, w is angular velocity and is equal to 2πf where f is frequency of turntable rotation
v= 2πfR
so,
T= R (6.28fR)/µg
T= 6.28fR²/µg
Answer:
in physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.
