Explanation:
<u>Displacement Vector</u>
Suppose an object is located at a position
and then moves at another position at
The displacement vector is directed from the first to the second position and can be found as
If the position is given as magnitude-angle data ( z , α), we can compute its rectangular components as
The question describes the situation where the initial point is the base of the mountain, where both components are zero
The final point is given as a 520 m distance and a 32-degree angle, so
The displacement is
Yes it does.
On the periodic table, tin is #50 and Mercury is # 80.
Answer:
Explanation:
Given a parallel plate capacitor of
Area=A
Distance apart =d
Potential difference, =V
If the distance is reduce to d/2
What is p.d
We know that
Q=CV
Then,
V=Q/C
Then this shows that the voltage is inversely proportional to the capacitance
Therefore,
V∝1/C
So, VC=K
Now, the capacitance of a parallel plate capacitor is given as
C= εA/d
When the distance apart is d
Then,
C1=εA/d
When the distance is half d/2
C2= εA/(d/2)
C2= 2εA/d
Then, applying
VC=K
V1 is voltage of the full capacitor V1=V
V2 is the required voltage let say V'
Then,
V1C1=V2C2
V × εA/d=V' × 2εA/d
VεA/d = 2V'εA/d
Then the εA/d cancels on both sides and remains
V=2V'
Then, V'=V/2
The potential difference is half when the distance between the parallel plate capacitor was reduce to d/2
I'm Pretty sure it's FRICTION
