There is no thing here I can answer so imma just say all of the above because I have no idea what else to say so thx for the points
Answer:
A-18500J
B-232.5 rad/s
Explanation:
A- As the cylinder rotates through 1000rad, it sweeps a distance of
So the work, which is distance times force, of the tension done on the cylinder through that distance is
W = Td = 50 * 370 = 18500 J[/tex]
B- The torque that exerts on the cylinder by the tension is
To = TR = 50*0.37 = 18.5 Nm
As the cylinder is hollow, its moments of inertia is
The torque is generating an angular acceleration of:
The time it takes to go from rest to 1000 rad
Therefore the final rotational speed is
Answer:
−1.9 × 10−5 Wb
Explanation:
Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux
Finding the area
Area = πr² = 3.14*0.075*0.075
Area=0.01767 m²
Magnetic flux = 0.01767*0.00110*cos 0
Magnetic flux =0.000019 = −1.9 × 10−5 Wb
The answer is d the ray of light gets refracted.
