Answer:
The law of multiple proportions states that when two elements can combine in different ratios to form different compounds, the masses of the element combining with the fixed mass of another element result in whole number ratios. This shows that the law of multiple proportions is followed
Explanation:
Answer:
It will take 2.68 minutes for them to reach each other.
Explanation:
We use the two following kinematic equations, making the final position the same (for the moment they meet each other):
locomotive 1 --> 
locomotive 2 --> 
we make the two xf equal, and solve for the time (t) using v = 95 km/h:

converting the hours into minutes by multiplying this value times 60;
t = 2.68 minutes
Answer:
a
x-component 
y-component 
b
Magnitude 
direction is 
Explanation:
From the question we are told that
The first vertical distance is 
The first horizontal distance is 
The second vertical distance is 
Generally the displacement is
x-component 
y-component 
Generally the helicopters displacement is mathematically evaluated as



The direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as
![\theta = tan ^{-1}[ \frac{48}{20}]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%20%5Cfrac%7B48%7D%7B20%7D%5D)
=> ![\theta = tan ^{-1}[ 2.4 ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%202.4%20%5D)
=> 
Answer:
Explanation:
A = 155 m at 25° North of west
B = 92 m due north
C = 64.7 m at an angle 50° East of north
Write the displacements in the vector form





(a)


(b)
