Answer:
(a) x=-3.15cm
(b)y=0cm
Step-by-step explanation:
Locate the point (4.2,4.9) cm and draw the vector 4.5i+3.j with the origin at this point, the end of the vector is going to be in the point (8.7,7.9). With point (2.2,0), after searching, draw a line to the right to represent that the direction of the field is toward the positive x-axis.
Draw a line in each point in the opposite direction of the field in that point, the point where these lines intersect each other is the position of the particle.
Is the point (-3.15,0)cm
(a) x=-3.15cm
(b)y=0cm
Answer:
3:5
Step-by-step explanation:
5a + 3b = 6b
5a=6b-3b
5a=3b
a/b= 3/5
a:b=3:5
0.836, 0.683, 0.386, and then 0.3
Answer:
All of them are not vertical angles.
