A small block of mass m = 2.00 kg slides, without friction, along the loop-the-loop track shown. The block starts from the point P a distance h = 57.0 m above the bottom of the loop of radius R = 18.0 m. a) What is the kinetic energy of the mass at the point A on the loop? b)What is the downward acceleration of the mass at the point A of the loop? c)What is the minimum height h for which the block will reach point A on the loop without leaving the track?

weight is the answer i just took the test

the correct answer is true

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
