For number 3, I believe it is B, as people subconsciously get the name Levi's into their head. When people say I want to go to Levi's stadium for a game, they connect it with good thoughts, and next time they want to get jeans they might think, what jean brand do I know, and think of Levi's.
For number 4, I believe it is D. A is untrue, and B and C have nothing to do with the exchange of information between consumers.
For number 5, it is C, Monopoly. Monopolies are when 1 company is the only one who sells a particular good or service. There are some monopolies, but most of them are by federal agencies and consumers most likely do not want to choose for those services.
For number 6, I believe it is A, right to consumer education. I originally thought it might be B, however, when I looked up B, there was no such law, and what came up is the right to consumer education. I am not 100% sure on this one, but your best bet is A I think.
Hope this helps!
Answer:
704m
Explanation:
Given, initial velocity, u=0m/s and final velocity v=65m/s
Acceleration a=3m/s 2
If d be the allowed length for the runway.
Using formula v*2 −u*2 =2aS
(65)*2−0*2 =2(3)d
⟹ d=65*2 /6=704.16∼704m
Answer:
v1 = 15.90 m/s
v2 = 8.46 m/s
mechanical energy before collision = 32.4 J
mechanical energy after collision = 32.433 J
Explanation:
given data
mass m = 0.2 kg
speed = 18 m/s
angle = 28°
to find out
final velocity and mechanical energy both before and after the collision
solution
we know that conservation of momentum remain same so in x direction
mv = mv1 cosθ + mv2cosθ
put here value
0.2(18) = 0.2 v1 cos(28) + 0.2 v2 cos(90-28)
3.6 = 0.1765 V1 + 0.09389 v2 ................1
and
in y axis
mv = mv1 sinθ - mv2sinθ
0 = 0.2 v1 sin28 - 0.2 v2 sin(90-28)
0 = 0.09389 v1 - 0.1768 v2 .......................2
from equation 1 and 2
v1 = 15.90 m/s
v2 = 8.46 m/s
so
mechanical energy before collision = 1/2 mv1² + 1/2 mv2²
mechanical energy before collision = 1/2 (0.2)(18)² + 0
mechanical energy before collision = 32.4 J
and
mechanical energy after collision = 1/2 (0.2)(15.90)² + 1/2 (0.2)(8.46)²
mechanical energy after collision = 32.433 J
Answer:
Motion definition: the action or process of moving or being moved.
