A200-turn rectangular coil having dimensions of 3.0 cm by 4.0 cm is placed in a uniform magnetic field of magnitude 0.87 t. (a) find the current in the coil if the maximum torque exerted on it by the magnetic field is 0.16 n. m.
(b) find the magnitude of the torque on the coil when the magnetic field makes an angle of 25° with the normal to the plane of the coil.

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
