1670 km/h; 40 200 km/day
<em>a) Velocity in kilometers per hour</em>
The conversion factors are 1 km/1000 m, 60 s/1 min, and 60 min/1 h.
We can string these together to get
Velocity = (465 m/1 s) x (1 km/1000 m) x (60s/1min) x (60 min/1 h)
= 1674 km/h
= 1670 km/h (three significant figures)
<em>b) Velocity in kilometers per day
</em>
The conversion factor is 24 h/1 day.
Velocity = (1674 km/1 h) x (24 h/1 day) = 40 200 km/day
It is tasteless and colorless.

Answer:
Te
K
Explanation:
Main group elements are elements designated and located on the s-block and p-block on the periodic table. The core group or prominent elements are the elements that make up those groups. These groupings comprise the most naturally rich and abundant elements. The main group elements are those whose characteristics are more predicted as a function of their periodic table location. From the given options, only Te and K are elements of the main-group.
