Explanation:
It is given that,
Mass of the box, m = 100 kg
Left rope makes an angle of 20 degrees with the vertical, and the right rope makes an angle of 40 degrees.
From the attached figure, the x and y component of forces is given by :
Let 
and 
is the resultant in x and y direction.
As the system is balanced the net force acting on it is 0. So,
.............(1)
..................(2)
On solving equation (1) and (2) we get:
(tension on the left rope)
(tension on the right rope)
So, the tension on the right rope is 1063.36 N. Hence, this is the required solution.
Fusion occurs in the Sun's core, releasing energy that is transferred outward. Once in the radiative zone, gamma rays are transferred by radiation. They are converted to other types of photons, which move into the convective zone, where they are transferred by convection. Finally, energy is emitted from the photosphere.
Answer:
4.399 Nm
Explanation:
The maximum Torque on a coil is given as,
τ = BNIA...................... Equation 1
Where τ = Maximum torque exerted on the coil, B = Magnetic Field, N = Number of turns, I = Current, A = Area.
Given: N = 45.5 Turns, B = 0.49 T, I = 26.7 mA = 0.0267 A,
A = πr², Where r = radius of the coil, r= 4.85 cm = 0.0485 m
A = 3.14(0.0485)²
A = 7.39×10⁻³ m².
Substitute into equation 1
τ = 45.5×0.49×26.7×7.39×10⁻³
τ = 4.399 Nm
The self-inductance of a solenoid is given by:
where
is the vacuum permeability
N is the number of turns
A is the cross-sectional area of the solenoid
l is the length of the solenoid
For the solenoid in our problem, N=3000, l=70.0 cm=0.70 m and the self-inductance is L=25.0 mH=0.025 H, therefore the cross-sectional area is
And since the area is related to the radius by
The radius of the solenoid is
