A 74.0 kg tightrope walker stands at the center of a rope. The rope supports are 10 m apart and the rope sags 8.00 ∘ at each end
1 answer:
Answer:
<em>285.79 N</em>
<em></em>
Explanation:
Mass m of tightrope walker = 74.0 kg
distance of both ends pf rope = 10 m
angle at both ends of the rope = 8.00°
acceleration a of leap = 7.80
Force exerted on the rope due to the acceleration will be,
F = ma
F = 74 x 7.80 = 577.2 N
<em>This force creates a tension that is evenly divided on the ropes from the midpoint, i.e force on each end of the rope = 288.6 N</em>
Tension T = F sin∅
T = 288.6 sin 8.00° = <em>285.79 N</em>

answer :
<em>w</em>f = M( v cos∅ )D / I
Explanation:
The Angular speed <em>wf </em>of the system after collision in terms of the system parameters and I can be expressed as
considering angular momentum conservation
Li = Lf
M( v cos∅ ) D = ( ML^2 / 3 + mD^2 ) <em>w</em>f
where ; ( ML^2 / 3 + mD^2 ) = I ( Inertia )
In terms of system parameters and I
<em>w</em>f = M( v cos∅ )D / I
The magnitude of the magnetic moment due to the electron's motion is .
The magnetic pull and direction of a magnet or other object that produces a magnetic field are referred to as the magnetic moment in electromagnetism. Things that have magnetic moments include electromagnets, permanent magnets, various compounds, elementary particles like electrons, and a number of celestial objects (such as many planets, some moons, stars, etc).
The term "magnetic moment" really refers to the magnetic dipole moment of a system, which is the portion of the magnetic moment that can be represented by an equivalent magnetic dipole or a pair of magnetic north and south poles that are only very slightly apart. The magnetic dipole component is adequate for sufficiently small magnets or over sufficiently large distances.
