A lightning bolt strikes one end of a steel lightning rod, producing a 14700-A current burst that lasts for 63 μs. The rod is 2.2 mm long and 2.3 cm in diameter, and its other end is connected to the ground by 30 mm of 7.8-mm-diameter copper wire.

A.) Find the potential difference between the top of the steel rod and the lower end of the copper wire during the current burst.

B.) Find the total energy deposited in the rod and wire by the current burst.

A lightning bolt strikes one end of a steel lightning rod, producing a 15300-A current burst that lasts for 67 μs . The rod is 2.5 m long and 2.3 cm in diameter, and its other end is connected to the ground by 38 m of 8.5-mm-diameter copper wire. A) Find the potential difference between the top of the steel rod and the lower end of the copper wire during the current burst. Express your answer using two significant figures....

Attached to each end of a thin steel rod of length 1.10 m and mass 6.60 kg is a small ball of mass 1.07 kg. The rod is constrained to rotate in a horizontal plane about a vertical axis through its midpoint. At a certain instant, it is rotating at 39.0 rev/s. Because of friction, it slows to a stop in 32.0 s. Assuming a constant retarding torque due to friction, find the following. A) Angular Acceleration rad/sec^2 B) Retarding...

You have a vertical metal rod, a spring with one end closed and the other end open so that it can slide down over the rod and then fly up when released, and a meter stick. The mass of the spring is 15g and its spring constant k is 6 N/m Your group decides to test the work-energy principle by stretching the spring a distance Dy = 30 cm, releasing it from rest and measuring how high it goes. Use...

A rigid massless rod is rotated about one end in a horizontal circle. There is a load of mass m attached to the center of the rod, and one of mass M attached to the outer end of the rod. The inner section of the rod sustains a tension that is three times as great as the tension that the outer section sustains. The mass ration of m/M is? Answer is 1 WHY?

A rod of mass "10m" and length "L" is hanging through a pivot at one end. A lump of clay of mass "m" is thrown perpendicular to the rod hitting it at the opposite end of the pivot. The lump sticks to the rod causing the rod to swing in a vertical circle up to an angle of 90o. Given [m, L] Determine: a. The initial speed of the lump of clay. b. The angular speed of the system just...

Steel Structures: The rolling process is one of the most frequently used forming processes for producing steel sections. Nonetheless, other forming and fabrication processes can be used to create a range of section shapes in the steel production process. For this assignment, you are required to review the other four types of steel forming/fabricating processes including drawing (manufacturing), extrusion, casting and forging Task 1: (IN YOUR WORDS) Write (250 words), Review the extrusion process and mention the type of section(s)...

One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle ofθ = 37°with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod isμs = 0.595.Determine the minimum distance x from point Aat which an additional weight w (the same as the weight of the rod) can be hung without causing the...
