Answer: Acids turn the indicator red, pink, orange, and yellow, while bases turn it green, blue, and purple.
the water specific heat will remain at 4.184.
Answer:
Explanation:
The magnitude on the charge at the bottom-left corner due to the charge on the top vertex of the triangle will act along the +ve x-axis and the +ve y-axis.
From Coulomb's law the magnitude of the forces on the charge at the bottom-left corner, due to the charge on the top vertex of the triangle are cos 60, and
The magnitude on the charge due to the charge at the bottom-right corner will only act in the -ve x-axis, since they repel each other (like charges repel). The magnitude is
The angle made by the upper charge to the charge we're considering is 60° with the horizontal.
The total force on the charge along the x-axis is
= cos 60 -
= -
==> -
For the y-axis, we have
= sin 60
=
The resultant force is
The common factors between the two x-axis force, and the y-axis force is
, we put this outside the square root (squaring this and square rooting will give us the initial value)
=
=
==>
the magnitude of the electric force on the charge at the bottom left-hand vertex of the triangle due to the other two charges is
=
Answer:
uh i think 1.2km im probably so wrong
