A 2000kg test car, traveling 60 ms hits a brick wall. Using motion pictures, the time involved is determined to be 0.050 s. What
2 answers:
Answer:
6,000 N-s
Explanation:
In order to calculate the impulse of the car when hitting a brick wall, we just have to first calculate the force of the car, force equals mass times acceleration, since the speed of the car is 60 m/s and the brick wall is at 0 m/s the acceleration would be 60 m/s, then you just multiply:
And now you just multiply that by the time that the car is involved in the hit with the wall.

Answer:
A. Yes, we will see growth. Yes, they will glow.
Explanation:
pGLO plasmid was engineered to be used as a vector in the field of biotechnology. It has an ampicillin resistance gene which acts as a reporter gene. It also has another reporter gene, GFP which shares its promoter (araC) with the gene responsible for metabolizing arabinose. GFP gene is thus translated only in the presence of arabinose in the medium since the promoter is active only in the presence of arabinose. Once the GFP gene is translated, the colonies glow with green fluorescence under UV light.
Here, the <em>E.Coli</em> colonies were grown successfully on LB + Ampicillin + Arabinose plate so they were ampicillin resistant. They also glowed in UV light. If these transformed colonies are inoculated in another LB + Ampicillin + Arabinose plate they will be able to grow successfully since they are ampicillin resistant. They will also glow because the new plate also has arabinose so the araC promoter will be active and expression of both GFP gene and arabinose metabolizing gene will occur.
