Tech A because it is best to use a knife
Answer:
The speed is minimum at t = 4 seconds.
The position function of a particle is given by
The velocity is given as,
Speed is computed as,
Differentiate above expression and equate to zero.
Thus, speed is minimum at t = 4 seconds.

Answer:
Option D
A mineral’s color reflects the wavelengths of light that are absorbed by the mineral.
Explanation:
Color is one of the physical properties of minerals. Many minerals have a wide range of colors but there are some minerals with one consistent color and such minerals are referred as monochromatic minerals for example azurite. Normally, the streak color tends to be less variable than the color of the whole mineral and impurities or minor chemical components in a mineral react and often control the display color of resultant mineral. Option D is incorrect since mineral's color don't reflect wavelengths of light absorbed by such minerals.
Answer:
A) Level D ( before development )
B) Level E ( After development )
Explanation:
A) Calculate the level of service before the development
First we calculate the base free flow speed ( BFFS )
= posted speed limit + 5 mi/hr.
= 50 + 5 = 55mi/hr.
Next determine free flow speed ( FFS )
= BFFS -
= 55 - 6.6 - 0.65 - 0 - 2.25 = 45 mi/hr.
The remaining part of the solution is attached below
The level of service = D
given that:
Vp = 1537.096 pc/hr/In
Density = 34.157 pc/mi/In
FFS = 45 mi/hr
B ) Calculate the level of service after the development
attached below is the detailed solution
The level of service = E
given that
Vp = 1816.568 pc/hr/In
Density = 40.368 pc/mi/In
FFS = 45 mi/hr
