Weight = Mass times Acceleration due to gravity.
Weight = 10 kg times 9.8 m/s^2
Weight = 98 kg
Answer:
(a) The magnitude of the electric dipole moment is 1.68 x 10⁻¹⁴ C.m
(b) The difference between the potential energies ΔU, is 4.6704 x 10⁻¹¹ J
Explanation:
Given;
magnitude of charge, q = 2 nC = 2 x 10⁻⁹ C
distance of separation, d = 8.4 μm = 8.4 x 10⁻⁶ m
strength of electric field, E = 1390 N/C
(a) the magnitude of the electric dipole moment
p = qd
p = (2 x 10⁻⁹ C)(8.4 x 10⁻⁶ m)
p = 1.68 x 10⁻¹⁴ C.m
(b) the difference between the potential energies for dipole orientations parallel and anti-parallel to E
ΔU = U(180) - U(0)
ΔU = 2pE
ΔU = 2(1.68 x 10⁻¹⁴ )(1390)
ΔU = 4.6704 x 10⁻¹¹ J

Answer: high pressures</h2>
The Ideal Gas equation is:
Where:
is the pressure of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin.
According to this law, molecules in gaseous state do not exert any force among them (attraction or repulsion) and the volume of these molecules is small, therefore negligible in comparison with the volume of the container that contains them.
Now, real gases can behave approximately to an ideal gas, under the conditions described above.
However, when <u>temperature is low</u> these gases deviate from the ideal gas behavior, because the molecules move slowly, allowing the repulsion or attraction forces to take effect.
The same happens at <u>high pressures</u>, because the volume of molecules is no longer negligible.
We have that the density of the fluid is

From the question we are told that
object of volume 0.0004m^3
density 6000kg/m^3
fluid of density 5000kg/m^3.
Force F=0.7N
Generally the equation for the Force is mathematically given as
