Answer:
1)FALSE
2)TRUE
3)FALSE
4) FALSE
Explanation:
1) Retrieving an entry at a given position is not slow ( it is done using index number ) hence the answer is FALSE
2) Adding an entry at the end of the list is Fast this is because in using array implementation a new entry is made immediately after the last position and it is done very fast as well. hence the answer is TRUE
3) Retrieving an entry at a given position ( from an ADT list ) that is been implemented using Vector is very fast this is simply because Indexing in vector is done at a fixed time hence the answer is FALSE
4) Adding an entry at the end of the list is slow using vector hence answer is FALSE
Answer:
Explanation:
Because it breaks the <u>l</u><u>a</u><u>w</u><u> </u><u>o</u><u>f</u><u> </u><u>m</u><u>o</u><u>m</u><u>e</u><u>n</u><u>t</u><u>s</u><u>.</u>
Net Force = mass * acceleration.
Therefore, Acceleration = Net force / mass
A=2000/500
A=4 m/s^2
Answer:
4 m/s
Explanation:
KE =
Velocity of balloon will be 4 m/s.

<h2>
Answer: B) It would be best to use a concave mirror, with the object to be ignited positioned halfway between the mirror and its center of curvature. </h2>
Explanation:
To start a fire it is more optimal to use a concave mirror than a plane mirror. This is because the concave mirror allows concentrating sunlight at a point (the focal point) on an object that acts as fuel and ignite the fire there.
For this it is necessary the object to be positioned between the center of curvature of the mirror and the mirror (its focus). Thus the rays of the Sun, when converging on the focus, will heat the object and make it burn.
Hence, the correct option is B.
