Answer:
The net force on the electron is given as:
F = 1.35 x 10⁻¹³ N j - 1.35 x 10⁻¹³ N i
Explanation:
Given:
charge on rod along x-axis = Q₁ = -15 x 10⁻⁶ C
charge on rod along y-axis = Q₂ = 15 x 10⁻⁶ C
distance of electron from rod 1 = r₁ = 0.4 m
distance of electron from rod 1 = r₂ = 0.4 m
charge on electron = q = -1.6 x 10⁻¹⁹ C
ε° = 8.85 x 10⁻¹² C²/Nm²
Electric force on charge due to rod 1:
F₁ = qE = 1/4πε°(qQ₁/r₁²)
F₁ = (9 x 10⁹ x -1.6 x 10⁻¹⁹ x -15 x 10⁻⁶)/0.4²
F₁ = 1.35 x 10⁻¹³ N
Negative negative repels each other so the rod will Force the electron in positive y-direction.
F₁ = 1.35 x 10⁻¹³ N j
Electric force on charge due to rod 2:
F₂ = qE = 1/4πε°(qQ₂/r₂²)
F₂ = (9 x 10⁹ x -1.6 x 10⁻¹⁹ x 15 x 10⁻⁶)/0.4²
F₂ = - 1.35 x 10⁻¹³ N
Opposite charges attract each other so the rod will force the electron in negative x-direction.
F₂ = - 1.35 x 10⁻¹³ N i
Net Force:
F = F₁ + F₂
F = 1.35 x 10⁻¹³ N j - 1.35 x 10⁻¹³ N i
Answer:
<u><em>Rate of dissolving compounds:</em></u>
If we increase the temperature of the solution, then the dissolving compound would dissolve more easily.
<u><em>Boiling Point of Compounds:</em></u>
If the inter-molecular forces of any compound is really strong, then the boiling point of the compound would be really high.

Explanation:
For which solid is the lumped system analysis more likely to be applicable?
<u>Answer</u>
The lumped system analysis is more likely to be applicable for the body cooled naturally.
<em>Question :Why?</em>
<u>Answer</u>
Biot number is proportional to the convection heat transfer coefficient, and it is proportional to the air velocity. When Biot no is less than 0.1 in the case of natural convection, then lumped analysis can be applied.
<u>Further explanations:</u>
Heat is a form of energy.
Heat transfer describes the flow of heat across the boundary of a system due to temperature differences and the subsequent temperature distribution and changes. There are three different ways the heat can transfer: conduction, convection, or radiation.
Heat transfer analysis which utilizes this idealization is known as the lumped system analysis.
The Biot number is a criterion dimensionless quantity used in heat transfer calculations which gives a direct indication of the relative importance of conduction and convection in determining the temperature history of a body being heated or cooled by convection at its surface. In heat transfer analysis, some bodies are observed to behave like a "lump" whose entire body temperature remains essentially uniform at all times during a heat transfer process.
Conduction is the transfer of energy in the form of heat or electricity from one atom to another within an object and conduction of heat occurs when molecules increase in temperature.
Convection is a transfer of heat by the movement of a fluid. Convection occurs within liquids and gases between areas of different temperature.
Answer:
2/3
Explanation:
In the case shown above, the result 2/3 is directly related to the fact that the speed of the rocket is proportional to the ratio between the mass of the fluid and the mass of the rocket.
In the case shown in the question above, the momentum will happen due to the influence of the fluid that is in the rocket, which is proportional to the mass and speed of the same rocket. If we consider the constant speed, this will result in an increase in the momentum of the fluid. Based on this and considering that rocket and fluid has momentum in opposite directions we can make the following calculation:
Rocket speed = rocket momentum / rocket mass.
As we saw in the question above, the mass of the rocket is three times greater than that of the rocket in the video. For this reason, we can conclude that the calculation should be done with the rocket in its initial state and another calculation with its final state:
Initial state: Speed = rocket momentum / rocket mass.
Final state: Speed = 2 rocket momentum / 3 rocket mass. -------------> 2/3
