1. To begin, check that this question is shown: The tallest building in the world, the Burj Khalifa in Dubai, is 0.828 kilometers high. What is the building's height in centimeters? (If this is not the question you see, click Next until it appears.)

A. What unit is given in the question?

B. What unit is asked for?

2. Look for the Unit Conversion Tile that has the unit "meter" on top and "kilometer" on the
bottom. This tile shows a conversion factor, or a ratio that compares two equivalent values.

A. According to this tile, how many meters are in a kilometer?

B. Look at the tile next to it. How many centimeters are in a meter?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

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.

what is the actual question though?
