Answer:
0.08 meters.
Explanation:
Extension= increase in length (∆L).
E= 21-13=8 cm
To convert cm to m, divide by 100
8 cm= 0.08 m.
I think it would be because solid wood is a lot heavier than plastic
Answer:
(a) 0.014 A
(b) 2 V
Explanation:
(a) Applying
V = IR'...................... Equation 1
Where V = Voltge, I = current, R = total resistance.
make I the subject of the equation
I = V/R'................... Equation 2
From the question,
Given: V = 12 V, R' = (122+232+500) ohms (The resistance are connected in series) = 854 ohms
Substitute these values into equation 2
I = 12/854
I = 0.014 A
(b) Applying
V' = V(R₁)/(R₁+R₂+R₃)...................... Equation 3
Where V' = Voltage across the 100 ohms resistor.
From the question,
V = 12V, R₁ = 100 ohm, R₂ = 200 ohm, R₃ = 300 ohm.
Substitute these values into equation 3
V' = (12×100)/(100+200+300)
V' = 1200/600
V' = 2 V
Answer:
i would say the third one

B. Polar Molecule
Explanation - polar means that the electrons are not shared evenly. Water (H2O) has two Hydrogen atoms which are positive because they give their electrons away, and one Oxygen atom which is negative because it received the electrons
