Answer:
Explanation:
This is not a nice question. On the surface, it looks like C and D are both correct.
Coming back to the starting point makes the displacement = 0. That means that the velocity is also 0.
On the other hand, the total displacement when going in a circle can also be zero.
To me the best answer is probably D, but I wouldn't be surprised if the poser of the question thinks it is C. I would answer D but hold your nose when you do it.
Blank are short programs that provide occupational training.
A: Certificates
B: Classes
C: Workshops
D: Sessions
I believe the answer might be C
Wich car would go faster an automatic or stick shift based on horse power or speed
Answer: In most cases, an automatic car will be quicker than a manual transmission car equivalent, which takes time to shift gears. And the fact is, an automatic and especially an automated manual can shift gears much quicker than a human driver.
Answer:
automatic car will go faster than a manual car
Which quantities are scalars?
O A. velocity
B. distance
C. acceleration
D. speed
select all that apply
Answer:
Explanation:
speed has no definite direction. Therefore it is a scalar.
distance also has no definite direction. It is a scalar.
The other 2 do have direction and they are vectors.
An increase in demand or a decrease in supply creates a.?
Answer:
An increase in demand or a decrease in supply will cause an increase in equilibrium price.
Explanation:
Which of the following are units that can be used to describe vector
quantities?
Check all that apply.
A. Meters per second squared
B. Meters
O c. Kilometers per hour
D. Kilograms
Answer:
Explanation:
All but kg can be vector quantities.
m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.
meters can be a vector or the unit of a vector. It is called displacement when it has direction.
km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail. hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.
kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.
Answer:
A
Explanation:
Which of the following is the best description of the term resultant
displacement?
O A. The scalar that joins all the points along the path.
O B. The total distance traveled.
O C. The shortest distance from the beginning point to the end point.
ОО
D. The average of all the displacement vectors.
In a recent television survey, participants were asked to answer ʺyesʺ or ʺnoʺ to the question ʺAre you in favor of the death penalty? ʺ Six thousand five hundred responded ʺyesʺ while 4100 responded ʺnoʺ. There was a fifty-cent charge for the call. A) stratified B) random C) cluster D) convenience E) systematic
Answer:
A) stratified
Explanation:
Total call including 6500 'yes' and 4100 'no' are 10600 and on each call there was a fifty cent charge. Total charge becomes 5300 $ so this is very straight forward data. And from this test two types of classes are made with cleared population in each class and such cleared population division is example of stratified sampling so this is right answer.
