Answer:
B. a ⊥ d
Step-by-step explanation:
If lines "a" and "d" are in the same plane, they are perpendicular to each other. If not, there is no relationship between the lines.
__
Lines parallel to the same line are parallel to each other, so a║c. <em>In the same plane</em>, a line perpendicular to one of two parallel lines is also perpendicular to the other. (For example, one side of a rectangle is perpendicular to both of the adjacent sides, which are parallel to each other.)
The appropriate choice is ...
a ⊥ d
__
<em>In 3 dimensions, ...</em>
Consider a cube. A given edge will be perpendicular to both of the two edges it meets at a corner.
It will not intersect (has no "perpendicular" relationship to) either of the edges parallel to those that meet at the corner at the other end of the space diagonal.
Answer:
a. how many tries do u have.
Step-by-step explanation:
Answer:
v= 2.66 m/sec
Step-by-step explanation:
supposing we have to find their speed just as he grabs her.
Applying law of conservation of Energy
That is
p_i= p_f
Initial momentum = p_i = 35×0+ 44×4.9= 210.6 kg.m/sec.
final momentum p_f= (35+44)v
let the final velocity of combined body be v
therefore,
79v= 210.6
v= 2.66 m/sec.
