An electric field has both magnitude and direction.
I don't think that's one of the first 3 choices.
Answer:
B= -40
The negative sign indicates the reverse direction to that of vector A.That is it is in the third quadrant.
Explanation:
Th resultant vector is obtained by adding the two vectors A and B
A + B= AB
25 + B= -15
25+ 15= -B
-B = 40
B= -40
Vector B has a magnitude of 40 and points in the opposite direction to that of vector A. The negative indicates the opposite direction.
When we reverse the vector B for adding we place a negative sign with the magnitude.
A vector is quantity defined by magnitude and direction. If the direction is left out it becomes a scalar.
Answer:
About 6.26m/s
Explanation:
Divide both sides by mass:
Since the point of equality of kinetic and potential energy will be halfway down the cliff, height will be 4/2=2 meters.
Hope this helps!
Answer: the two states that are fluid are;-
<u>#{1} liquid</u>
<u>#{2} gas </u>
Explanation:
as we know that there are mainly three states of substance
but among them only two of them can fluid and takes the shape of the container that are liquid and gas
