The net charge on the inner surface of the conductor is 7Q, while the net charge on the outer surface of the conductor is -5Q.

In electrostatic equilibrium, charges distribute themselves on the surface of a conductor in such a way that the electric field inside the conductor is zero. Based on this principle, we can analyze the situation step by step:

1. Initially, when the point charge of 7Q is placed inside the cavity of the conductor, the charge redistributes itself on the inner and outer surfaces of the conductor. In order to achieve electrostatic equilibrium, the charges on the inner and outer surfaces of the conductor must be such that the electric field inside the conductor is zero.

2. Since the conductor is electrically neutral, the net charge on the outer surface of the conductor will be equal in magnitude but opposite in sign to the charge inside the cavity. Therefore, the net charge on the outer surface is -7Q.

3. When an additional charge of -5Q is placed on the surface of the inner cavity, the charge redistributes again to achieve electrostatic equilibrium. The charge on the inner surface of the conductor will now be equal in magnitude but opposite in sign to the additional charge placed on the inner cavity. Hence, the net charge on the inner surface is -(-5Q), which simplifies to +5Q.

The net charge on the inner surface of the conductor is 5Q, while the net charge on the outer surface of the conductor is -7Q.

Explanation:

The distance travelled by the car before it comes to a full stop is 65.59m if its initial velocity is 30m/sec.

Now, we need to find the distance of a car travelled, so we can use third equation of motion which is

v² - u² =2aS

where v is final velocity ,

u is the initial velocity

a is the acceleration

and S is the displacement of object

Since, final velocity of object is zero because car comes to rest

=>v=0,u=30m/sec, a=?,S=?

Now, we know that force applied by kinetic friction on car is given by =μmg where μ is coefficient of kinetic friction, m is the mass and g is the acceleration due to gravity

=>F=μmg ------eq1

Now,μ=0.70,m=?,g=9.8m/sec²

We also know that F=ma------eq2

Comparing eq1 and eq2

=>μmg=ma

=>a=μg

=>a=0.70ˣ9.8

=>a=6.86m/sec²

Now, 0² - (30)² = 2ˣ(-6.86)ˣS

=>900=2ˣ6.86ˣS

=>S=900/13.72

The figure below showing electrons moving along an electric current towards and away from the light bulb with arrows pointing right and left in both directions, indicates that the current is alternating.

What is Electric Current?

It is the rate at which electric charges move through a circuit, measured in amperes (A). Electric current is caused by the movement of electrons, which carry a negative charge, and it flows from a region of higher electric potential to a region of lower electric potential.

Electric current can be produced by a variety of sources, including batteries, generators, and power plants. The amount of current that flows through a circuit depends on the voltage, or electric potential difference, and the resistance of the circuit. Ohm's law describes the relationship between these variables: current is equal to voltage divided by resistance (I = V/R).

In an alternating current (AC), the flow of electric charge changes direction periodically, typically 50 or 60 times per second (50 or 60 Hertz). The direction of the current reverses periodically, causing the electrons to move back and forth, as shown in the figure. In a direct current (DC), the flow of electric charge is always in one direction, and the electrons move in one direction only.

A two-stroke engine is a type of internal combustion engine that completes a power cycle in just two strokes of the piston instead of four as in a four-stroke engine.

The engine works by first drawing in a mixture of air and fuel into the cylinder through an intake port. As the piston moves upwards, it compresses the mixture, which is then ignited by a spark plug. This ignition causes a rapid combustion of the fuel mixture, generating a high-pressure wave that drives the piston downwards. As the piston moves back up, it expels the exhaust gases through an exhaust port. The cycle then repeats as the piston moves back down to draw in a new mixture of air and fuel. Two-stroke engines are lightweight, powerful, and commonly used in small vehicles like motorcycles, boats, and chainsaws.

The distances from the center of the spherical object for the given potentials are (a) 7.19 mm , (b) 14.4 mm , (c) 28.8 mm

determine the distance from the center of the spherical object at which the potential is equal to a specific value, we need to use the equation for the electric potential of a point charge:

V = k * (Q / r),

where V is the electric potential, k is the electrostatic constant (k ≈ 8.99 ×\(10^9\) N m²/C²), Q is the charge of the object, and r is the distance from the center of the object.

We can rearrange the equation to solve for r:

r = k * (Q / V).

Charge of the object (Q) = 8.00 nC = 8.00 × 10^(-9) C.

Electric potentials:

(a) V = 100 V

(b) V = 50.0 V

(c) V = 25.0 V

Using the values, we can calculate the distances for each potential:

(a) r = (8.99 × \(10^9\) N m²/C²) * (8.00 × \(10^{(-9)\) C) / 100 V = 7.19 × \(10^{(-3)\) m

(b) r = (8.99 × \(10^9\) N m²/C²) * (8.00 × \(10^{(-9)\) C) / 50.0 V = 1.44 × \(10^{(-2)\) m

(c) r = (8.99 × \(10^9\)N m²/C²) * (8.00 ×\(10^{(-9)\) C) / 25.0 V = 2.88 × \(10^{(-2)\) m

The distances from the center of the spherical object for the given potentials are :

(a) 7.19 mm

(b) 14.4 mm

(b) The tension on the surface of a femoral artery having a diameter of 0.00660 m if the blood pressure is 15990 Pa is 26.4675 Pa m.

(a) LaPlace's equation for tension in spherical structures, such as aneurysmal vessel segments and alveoli, is given by:

γ = (P * R) / 2

γ represents the wall tension,

P is the pressure inside the structure, and

R is the radius of the structure.

(b) To estimate the tension on the surface of a cylindrical structure, like a femoral artery, we can use LaPlace's Law for cylindrical structures:

The speed of the cars after the collision is approximately 19.47 m/s.

To determine the speed of the cars after the collision, we need to apply the principle of conservation of momentum.

The momentum of an object is given by the product of its mass and velocity: momentum = mass × velocity.

Given:

Mass of the first car (m₁) = 1500 kg

Velocity of the first car (v₁) = 90 km/h toward the east

Mass of the second car (m₂) = 3000 kg

Velocity of the second car (v₂) = 60 km/h toward the south

To use the principle of conservation of momentum, we need to convert the velocities to a common unit. Let's convert them to m/s.

Converting velocities:

v₁ = 90 km/h = (90 × 1000) / 3600 = 25 m/s (eastward)

v2 = 60 km/h = (60 × 1000) / 3600 = 16.7 m/s (southward)

The total momentum before the collision is equal to the total momentum after the collision, as momentum is conserved.

Total momentum before collision = Total momentum after collision

(m₁ × v₁) + (m₂ × v₂) = Total mass × Final velocity

(1500 kg × 25 m/s) + (3000 kg × 16.7 m/s) = (1500 kg + 3000 kg) × Final velocity

Simplifying the equation:

37500 kg·m/s + 50100 kg·m/s = 4500 kg × Final velocity

87600 kg·m/s = 4500 kg × Final velocity
