Fo 4. (10 points) A 2.0 m conductor is formed into a square and placed in the horizontal a-pl ane. A magnetic field is oriented 30.0° above the horizontal with a strength of 2.0 T. What is the magnetic flux through the conductor? A) 0.43 T- m2 B) 4.0 T- m2 C) 0.5 T, m?, D) 0.25 T-m A. si
3. A conductor having an area 0.14m2 is placed in the horizontal -plane. A magnetic field is oriented 30.0P with the normal to the plane of the conductor. with a strength of 1.0 T What is the magnetic flux through the conductor?
5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.
A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.350 rev/s. What is its angular velocity (in rev/s) after a 25.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest. ______ rev/s
A 1.80 m radius playground merry-go-round has a mass of 120 kg and is rotating with an angular velocity of 0.330 rev/s. What is its angular velocity, in rev/s, after a 29.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest.
A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.350 rev/s. What is its angular velocity (in rev/s) after a 22.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest. Incorrect: Your answer is incorrect. rev/s
A 2.44-m radius playground merry-go-round has a mass of 109.8 kg and is rotating with an angular velocity of 0.71 rev/s. What is its angular velocity after a 45.8-kg child gets onto it by grabbing its outer edge? The child is initially at rest.
39. A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.500 rev/s. What is its angular velocity after a 22.0-kg child gets onto it by grabbing its outer edge? The child is initially at rest.
12) A 24.5-kg child (momentum of inertia is mR2 )is standing on the outer edge of a horizontal merry-go-round (treat the merry-go-around as solid cylinder, which has moment of inertia of 1/2mR2) about a vertical axis through its center and a radius of 2.50 m. The entire system (including the child) is initially rotating at 0.200 rev/s a) Find the angular velocity if the child moves to a new position 1.25 m from the center of the merry-go-round. b) If...
