Answer:
The one at the front is the driver. he one at the back is the brakeman.
Explanation:
In either a two or a four person bobsled team, the one at the front of the sled is called driver. The one at the back is called the brakeman, and is the one that pushes the back of the sled. The brakeman is the one that jumps in last as the sled gains speed.
In case of the four person, the other two team participants are just referred as riders.
0.29 m/s is the speed of this wave.
How can we determine a wave's speed?
Given: The wave's traveling wavelength is () = 35 cm
The wave's period (t) is 1.2 seconds.
The wave's frequency is 0.833 Hz.
We must ascertain a wave's wave speed.
Formula for wave speed is 35 x 0.833 (wavelength x frequency).
= 29.167 cm/sec
= 0.29 m/sec
As a result, the wave's speed is 0.29 m/s.

“Intelligent Design” (henceforth ID) is the view that the universe gives evidence of being the product of an intelligent designer. As such it is a very old view. Certainly this was the position of the biblical writers (as Ps. 19:1, Rom. 1:18-20). Historically, many have articulated this position by means of the “teleological argument:” that when unintelligent beings act for a purpose, they must be under the control of a personal intelligence.
