Acoil lies flat on a level tabletop in a region where the magnetic field vector points straight up. the magnetic field suddenly grows stronger. when viewed from above, what is the direction of the induced current in this coil as the field increases? a. counterclockwiseb. clockwise initially, then counterclockwise before stoppingc. clockwised. there is no induced current in this coil

Note: the following questions are unrelated to the balmer series or the martian. refer to your course notes. a sun-sized star will spend most of its lifetime as a: white dwarf b. red giant c. protostar d. main-sequence star

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.)

Am i correct on these two physics questions?
