I am pretty sure that <span>the following whihc cannot be determined by looking at the phase diagram is definitely </span>D. system pressure. I consider this one to be correct because only this point is not included into<span> phase diagram and can't be determined itself. Hope it will help! Regards!</span>
Answer:
2.16×10⁻⁶ N
Explanation:
Applying,
F = kqq'/r² (coulomb's Law)....................... Equation 1
Where F = electrostatic force, k = coulomb's constant, q = charge on the styrofoam, q' = charge on the grain of salt, r = distance between the charges.
From the question,
Given: q = 0.002 mC = 2.0×10⁻⁶ C, q' = 0.03 nC = 3.0×10⁻¹¹ C, r = 0.5 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = (2.0×10⁻⁶)(3.0×10⁻¹¹)(8.99×10⁹)/0.5²
F = 2.16×10⁻⁶ N
Answer:
The current can't 'split down the parallel branch, because the diode is reverse biased so is blocking the flow of current. So basically it's acting as an open circuit. Also when the current flows it wouldn't reduce the currents amount flow through the resistor.

Answer:
0.3 N
Explanation:
mass of cork = 0.01 kg, density of cork = 250 kg/m^3
density of water = 1000 kg/m^3, g = 10 m/s^2
Tension in the rope = Buoyant force acting on the cork - Weight of the cork
Buoyant force = volume of cork x density of water x g
= mass x density of water x g / density of cork
= 0.01 x 1000 x 10 / 250 = 0.4 N
Weight of cork = mass of cork x g = 0.01 x 10 = 0.1 N
Thus, the tension in the rope = 0.4 - 0.1 = 0.3 N
