Answer:
magnitude=34.45 m
direction=
Explanation:
Assuming the initial point P1 of this vector is at the origin:
P1=(X1,Y1)=(0,0)
And knowing the other point is P2=(X2,Y2)=(19.5,28.4)
We can find the magnitude and direction of this vector, taking into account a vector has a initial and a final point, with an x-component and a y-component.
For the magnitude we will use the formula to calculate the distance
between two points:
(1)
(2)
(3)
(4) This is the magnitude of the vector
For the direction, which is the measure of the angle the vector makes with a horizontal line, we will use the following formula:
(5)
(6)
(7)
Finding
:
(8)
(9) This is the direction of the vector
Answer:
Transition metal.
Explanation:
Reason;in periodic table gold is third element in eleventh column. So its classified as TRANSITION METAL. Gold contain 79 protons, 79 electrons and 118 neutrons and gold is the most abundant isotope.
Hope i helped you..
Not always. It depends on how
Many volts there are
