Answer: option <span>A) a train moving north of east at an angle of 25°
</span>
Explanation:
1) You need to choose your axis. In this case North is vertical and positive, South is vertical and negative, East is horizontal and positive, and West is horizontal and negative.
2) The vector with the two positive components is a vector in the first quadrant (North and East). That is what North of East 25° means.
3) Regarding the other options:
<span>B) a bus moving North of East at an angle of 95°: since the angle is greater tnan 90° the vector is in the second quadrant: its horizontal component is negative.

Answer:
Explanation:
We are given that
Mass,m=148 g
Length,L=6 cm
Velocity,u'(0)=10 cm/s
We have to find the position u of the mass at any time t
We know that
Where g=
u(0)=0
Substitute the value
Substitute u'(0)=10
Substitute the values
Answer:
Moving them farther apart
Explanation:
The electric field between the two charges Q and q separated by a distance r is given by
It shows that the electric field is inversely proportional to the square of the distance between two charges.
So, as the distance between two charges increases, the electric filed between the two charges decreases.
The correct answer is this one: "D) significantly more than 100 billion gallons ." Clouds dump around 100 billion gallons of water on rainforests each year. The amount of rain is evaporated from the rivers, lakes and surface of rainforests each year is significantly more than 100 billion gallons<span> </span>
