Aski lift has a one-way length of 1 km and a vertical rise of 200 m. the chairs are spaced 20 m apart, and each chair can seat three people. the lift is operating at a steady speed of 10 km/h. neglecting friction and air drag, and assuming that the average mass of each loaded chair is 250 kg, determine the power required to operate this ski lift. also, estimate the power required to accelerate this ski lift in 16 s to its operating speed when it is first turned on.
power is needed for (1) acceleration and (2) lifting the loaded chairs. this two parts can be calculated separately and then added together.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

answer///terminator or twilight zone;

at right angles to each other

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
