Explanation Given data: m = 200 g , B = 0.50 T and L = 10 cm . Formula used: Write the expression for net torque ( τ ) . τ = I L 2 B sin θ (1) Here, I is the current, B is the magnetic flux density, and L 2 is the area of the loop. Consider the conversion factor from grams to kilo grams. 1 g = 1 1000 kg Refer to Figure VI. 3 in the text book for a square loop of wire. As the square loop of wire consists of 4 sides, then the mass ( m side ) at each side of the square loop of wire is 50 g ( 200 g 4 ) . Consider the conversion factor from grams to kilo grams. m side = 50 ( 1 g ) = 50 ( 1 1000 kg ) = 50 ( 0.001 kg ) = 0.05 kg To make the loop to be steady, we have ∑ τ = 0 , to compute the torques around the pivot axis. No torque is generated on the two sides of the axis, which are perpendicular, so all the torque must be generated on the side parallel to the axis. From Figure VI. 3, the expression for downward torque ( τ ) is, τ = 2 m side g ( L 2 ) + m side g L Here, g is the acceleration due to gravity, which is known as 9.8 m s 2 , m side is the each side of the mass of a square loop of wire, and w is the width. Substitute 0.05 kg for m side , 9.8 m s 2 for g , and 10 cm for L , τ = 2 ( 0.05 kg ) ( 9.8 m s 2 ) ( 10 cm 2 ) + ( 0.05 kg ) ( 9

3.63 • Leaping the River II. A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land? Figure P3.63 53.0° 100 m 40.0 m→ 15.0 m

Please solve and answer the question correctly please. Thank you!!

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand? Ignore air resistance.
