Answer:
B i think is the answer
Explanation:
i feel like it is B because if you put them together and the answer is 1.5 so it is B
Answer:
B.) to determine that electric beams in cathode ray tubes were actually made of particles
Explanation:
This is the right answer i just took the quiz on edge.
From the starting depth to the surface, the vertical distance is 35 ft.
From the surface to the peak of the jump, the vertical distance is 27 ft.
From the peak of the jump to the surface, the vertical distance is 27 ft.
From the surface to the ending depth, the vertical distance is 18 ft.
Then the total vertical distance is ...
35 ft + 27 ft + 27 ft + 18 ft = 107 ft
I'm really not sure if this is right but I'll try.
The distance that the dog traveled is probably all of the distances added up. I would guess that it's 67 meters in total.
The displacement is a little more tricky but you pretty much have to put a mental map in your head. Since East and West are both 8 meters, they cancel each other out. He travels more southern and that means the displacement is 9 meters south of his original location
Answer:
R=19.5m
= 4.65° S of W
Explanation:
Refer the attached fig.
displacement of the x and y components
x-component displacement is (
) = 
= A 
(20°) + B 
(40°)
= -12.0(20°) + 20.0(40°)
= -19.425m
x-component displacement is (
) = 
= A (20°) - B (40°)
= 12.0(20°) - 20.0(40°)
= -1.579
resultant displacement
∴
R = 
=
=19.5m
= 
= 
= 4.65° S of W
