Ok so v is the velocity. Assuming it is constant, v = 2m/s
At 6 seconds x= 12.0m
Answer:
Shawn's speed relative to Susan's speed = 10 mph
Resultant velocity = 82.32 mph
Explanation:
The given data :-
i) Susan driving in north and speed of Susan is ( v₁ ) = 53 mph.
ii) Shawn driving in east and speed of Shawn is ( v₂ ) = 63 mph.
iii) The speed of both Susan and Shawn is relative to earth.
iv) The angle between Susan in north and Shawn in east is 90°.
We have to find Shawn's speed relative to Susan's speed.
v₂₁ = v₂ - v₁ = 63 - 53 = 10 mph
Resultant velocity,

v = 82.32 mph
Answer:A) noble gases
Explanation: key word gas. if you fart it smells and other gases harm.
The height for the tropopause is the tropopause is about 20 km (12 miles or 65,000 feet) above sea level. It's temperature typically, drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet).
Answer:
There is no chemical combination of the substances in a mixture, so they retain their physical properties. There is the same composition throughout a homogeneous mixture. The structure of a heterogeneous mixture differs.
