A circular coil of 204 turns has a radius of 2.63 cm. (a) Calculate the current that results in a magnetic dipole moment of magnitude 3.43 A·m2. (b) Find the maximum magnitude of the torque that the coil, carrying this current, can experience in a uniform 50.8 mT magnetic field.

In the image, the arrow is pointing to a celestial object. which attribute disqualifies the object from being a planet?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?
