A long piece of wire of mass 0.086kg and total length of 4.43m is used to make a square coil with 63 turns. The coil is hinged along a horizontal side, carries a 3.38A current, and is placed in a vertical magnetic field with a magnitude of 0.0104T. Determine the angle that the plane of the coil makes with the vertical when the coil is in equilibrium. Submit Answer Tries 0/10 Find the torque acting on the coil due to the magnetic force at equilibrium. Submit Answer Tries 0/10 Singly charged uranium-238 ions are accelerated through a potential difference of 2.00kV and enter a uniform magnetic field of 1.06T directed perpendicular to their velocities. Determine the radius of their circular path. Submit Answer Tries 0/10 Repeat for uranium-235 ions. Submit Answer Tries 0/10 What is the required radius of a cyclotron designed to accelerate protons to energies of 35.9MeV using a magnetic field of 5.21T? Submit Answer Tries 0/10

A measurement of the circumference of a disk has an uncertainty of 2.6mm. How many mea-surements must be made so that this circumference can be estimated with an uncertainty of only0.52 mm?

Q.5. What could be the possible reasons for errors in measurements?

6. If an object has a velocity of 27.8 ft/sec what is the velocity in km/hr?

What is the difference between accuracy and precision? Explain 2. Calculate the volume and percent error/uncertainty in the volume of a rectangular sample block of length 13.51 ±0.05 cm, width 6.23 ±0.02 cm, and thickness of 1.76±0.02 cm. 3. Calculate the mass density and uncertainty in the mass density of the sample block. Mass of the block is 289± 1gr. 1.

solve this and provide step by step your calculation
