calculate the power being dissipated by the third resistor p3, in watts.

The second satellite orbits at a distance greater than r, as the second satellite has a lower speed than the first, its centripetal force is also lower. To maintain a balance with the gravitational force, the distance r must be larger. This is because, in the equation above, as v decreases, r must increase to keep the equation balanced.

To determine the distance from the center of the Earth for the second satellite, we need to consider the following relationship: gravitational force equals centripetal force. For a satellite in a stable orbit, the equation is:
F_gravity = F_centripetal
G * (m * M_earth) / r² = m * v² / r
where G is the gravitational constant,
m is the mass of the satellite,
M_earth is the mass of the Earth,
r is the distance from the center of the Earth, and
v is the orbital speed.

Since the second satellite has a lower speed than the first, its centripetal force is also lower. To maintain a balance with the gravitational force, the distance r must be larger. This is because, in the equation above, as v decreases, r must increase to keep the equation balanced.

Therefore, the second satellite orbits at a distance greater than r.

The volume of water that will be displaced for pure gold is of 51813 kg/m³ and your answer is correct.

The density of pure gold is 19.3 g/cm³ or 19300 kg/m³. Therefore, the volume of the solid gold statue can be calculated by dividing its mass (1.00 kg) by its density:

Volume of solid gold statue = mass / density = 1.00 kg / 19300 kg/m³ = 5.1813 × 10⁵ m³

When the statue is lowered into the container of water, it will displace an amount of water equal to its own volume. Therefore, the volume of water displaced will also be 5.1813 × 10²-5 m³.

Finally, we can calculate the density of the statue by dividing its mass by the volume of water displaced:

Density of statue = mass / volume of water displaced = 1.00 kg / (5.1813 × 10²-5 m³) = 19300 kg/m³

This matches the density of pure gold, confirming that the statue is indeed made of solid gold.

The equation for calculating resistance is:

R = ρ * (L/A)

where R is resistance, ρ is resistivity, L is the length of the material, and A is the cross-sectional area of the material.

As the cross-sectional area increases, resistance decreases because there is more space for electrons to flow through. The larger the area, the more pathways electrons have to travel through, reducing the chance of collisions with other particles, thus lowering the resistance.

Regarding the continuity equation (A1v1=A2v2), it applies to the flow of fluids in a pipe or a tube. Electrical current does not follow this equation because it is not a fluid.

To answer what is a perpendicular bisector of the dipole and what is the equation to find its electric field and which way will the electric field point and what is the electric potential here.

The perpendicular bisector of a dipole is a line or plane that is perpendicular to the dipole axis and bisects the dipole, dividing it into two equal halves. In the context of an electric dipole, it refers to a line or plane that passes through the midpoint of the charges and is perpendicular to the line connecting them.

The electric field of a dipole can be calculated using the following equation:

E = (1/4πε₀) * (2pq / r³) * (sinθ),

where E is the electric field, ε₀ is the vacuum permittivity, p is the dipole moment (charge multiplied by the distance between the charges), q is the point charge, r is the distance from the dipole, and θ is the angle between the dipole axis and the observation point.

The electric field will point away from the positive charge and towards the negative charge, following the dipole moment's direction.

At the perpendicular bisector of the dipole, the electric potential (V) is zero because the contributions from the positive and negative charges cancel each other out. This can also be seen in the equation for the electric potential of a dipole:

The ball over the narrow tube will levitate higher than the ball over the wide tube. This is due to the Bernoulli principle, which states that as the speed of a fluid (in this case, air) increases, its pressure decreases.

As air moves through the narrow section of the tube, it must speed up to fit through the smaller space.

This results in a decrease in air pressure, which causes the ball to rise. On the other hand, as air moves through the wide section of the tube, it has more space and does not need to speed up as much, resulting in a higher air pressure.

This higher pressure pushes down on the ball, preventing it from levitating as high.

Therefore, the ball over the narrow tube will experience a greater force upwards due to the lower pressure, causing it to levitate higher than the ball over the wide tube.

Explanation:

The electric flux through the cylinder due to an infinite line of charge depends on the electric field passing through the cylinder and the surface area of the cylinder. As the surface area of the cylinder changes, the electric flux also changes accordingly.

(a) To find the electric flux through the cylinder due to the infinite line of charge, we need to first determine the electric field passing through the cylinder. Since the line of charge is parallel to the cylinder's axis, the electric field lines will also be perpendicular to the surface area of the cylinder. Therefore, the electric flux through the cylinder can be calculated as:

Φ = E * A

Where E is the electric field, and A is the area of the cylinder. Since the electric field due to an infinite line of charge is given as E = λ/2πεr, where λ is the charge per unit length, ε is the electric constant, and r is the distance from the line of charge, we can calculate the electric field at r = 0.250 m as:

[tex]\begin{equation}E = \frac{3.00\ \mathrm{mC/m}}{2\pi\epsilon_0(0.250\ \mathrm{m})} = 3.59 \times 10^6\ \mathrm{N/C}\end{equation}[/tex]

And the area of the cylinder is:

[tex]$A = 2\pi rl + 2\pi r^2 = 2\pi(0.250,m)(0.400,m) + 2\pi(0.250,m)^2 = 0.942,m^2$[/tex]

Therefore, the electric flux through the cylinder is:

[tex]$\Phi = (3.59 \times 10^6,N/C) \times (0.942,m^2) = 3.38 \times 10^6,Nm^2/C$[/tex]

(b) If the radius of the cylinder is increased to 0.500 m, the area of the cylinder will increase, while the electric field will decrease. The new area of the cylinder will be:

[tex]$A = 2\pi rl + 2\pi r^2 = 2\pi(0.250,m)(0.400,m) + 2\pi(0.500,m)^2 = 1.83,m^2$[/tex]

The new electric field at r = 0.500 m can be calculated as:

[tex]$E = \dfrac{3.00,mC/m}{2\pi\epsilon(0.500,m)} = 2.27 \times 10^6,N/C$[/tex]

Therefore, the electric flux through the cylinder with r = 0.500 m is:

[tex]$\Phi = (2.27 \times 10^6,N/C) \times (1.83,m^2) = 4.16 \times 10^6,Nm^2/C$[/tex]

(c) If the length of the cylinder is increased to 0.800 m, the area of the cylinder will increase while the electric field will remain the same. The new area of the cylinder will be:

[tex]$A = 2\pi rl + 2\pi r^2 = 2\pi(0.250,m)(0.800,m) + 2\pi(0.250,m)^2 = 1.26,m^2$[/tex]

Therefore, the electric flux through the cylinder with l = 0.800 m is:

[tex]$\Phi = (3.59 \times 10^6,N/C) \times (1.26,m^2) = 4.52 \times 10^6,Nm^2/C$[/tex]

Your answer :- A racing greyhound running around a 45m diameter semi-circle at a constant speed of 15m/s experiences an acceleration of 10 m/s² or approximately 1.02 g.

To find the acceleration of a racing greyhound running around a 45m diameter semi-circle at a constant speed of 15m/s, we will use the centripetal acceleration formula:

Acceleration = (v^2) / r

Where "v" is the constant speed (15m/s) and "r" is the radius of the semi-circle. Since the diameter is 45m, the radius (r) will be half of that, which is 22.5m.

Now, we can plug in the values:

Acceleration = (15^2) / 22.5
Acceleration = 225 / 22.5
Acceleration = 10 m/s^2

To express the acceleration in terms of g (where g is the acceleration due to gravity, approximately 9.81 m/s²), we simply divide the acceleration by g:

Acceleration in terms of g = 10 m/s² / 9.81 m/s²
Acceleration in terms of g ≈ 1.02 g

So, a racing greyhound running around a 45m diameter semi-circle at a constant speed of 15m/s experiences an acceleration of 10 m/s² or approximately 1.02 g.

Answer:

To find the magnitude of the average force exerted on the wall by the ball, we can use the impulse-momentum theorem, which relates the impulse exerted on an object to the change in momentum of that object:

Impulse = Change in momentum

We can express the impulse as the product of the average force and the time for which it acts:

Impulse = Average force × Time

Since the ball rebounds horizontally, its initial and final momenta have the same magnitude but opposite directions, so the change in momentum is:

Change in momentum = 2 × (final momentum) = 2 × (0.40 kg × 3.0 m/s) = 2.4 kg m/s

Using the formula for impulse, we can then solve for the average force:

Average force = Impulse / Time = (2.4 kg m/s) / 0.20 s = 12 N

Therefore, the magnitude of the average force exerted on the wall by the ball is 12 N.

If the plane requires 0.9 mile of runway and a speed of 190 miles per hour in order to lift off the plane's acceleration is approximately 3.80 mi/hr₂.

We can use the following kinematic equation to solve for the plane's acceleration:

v₂= u₂ + 2as

where v is the final velocity (190 mph), u is the initial velocity (0 mph), a is the acceleration, s is the distance traveled (0.9 mile).

First, we need to convert the distance from miles to feet, since the unit of acceleration is miles per hour squared (mi/hr₂) and we want to keep the units consistent.

1 mile = 5280 feet

So, the distance traveled is:

s = 0.9 mile * 5280 feet/mile = 4752 feet

Plugging in the known values into the kinematic equation, we get:

(190 mph)₂ = (0 mph)₂ + 2a(4752 feet)

Simplifying, we get:

36100 = 9504a

Solving for a, we get:

a = 36100/9504 = 3.799 mi/hr₂

The rocket is going 14 m/s (or approximately 31.3 mph) when the engine cuts out.

We can solve this problem using the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy. In this case, the work done by the rocket engine is equal to the initial kinetic energy of the rocket:

Work done by rocket engine = Initial kinetic energy of rocket

We can write the work done by the rocket engine as the product of force and distance:

Work done by rocket engine = Force x Distance

The force exerted by the rocket engine is given by the thrust of the engine, which is not provided in the problem. However, we know that the rocket is launched vertically, so the force exerted by the rocket engine is equal to the weight of the rocket:

Force = Weight = mass x gravity

where mass is the mass of the rocket and gravity is the acceleration due to gravity, which is approximately 9.8 m/s^2 on the surface of the Earth.

Using the given values, we can calculate the force exerted by the rocket engine:

Force = mass x gravity = 0.80 kg x 9.8 m/s^2 = 7.84 N

We also know that the work done by the rocket engine is 1500 J over a distance of 35 m:

Work done by rocket engine = Force x Distance = 7.84 N x 35 m = 274.4 J

Therefore, the initial kinetic energy of the rocket is 1500 J, and we can use the work-energy principle to find the final velocity of the rocket:

Work done by rocket engine = Initial kinetic energy of rocket

274.4 J = (1/2) x 0.80 kg x v^2

where v is the final velocity of the rocket.

Solving for v, we get:

v = sqrt(2 x 274.4 J / 0.80 kg) = 14 m/s

Therefore, the rocket is going 14 m/s (or approximately 31.3 mph) when the engine cuts out.

the tangential speed of the ball is 7.35 m/s.

The period of frequency of the ball is 2.56 s.

a. The centripetal acceleration is the acceleration of an object moving in a circular path towards the center of the circle. Therefore, the ball's acceleration is directed towards the center of the circle.

b. The tangential speed is the speed of an object moving in a circular path along the tangent to the circle at a given point. The tangential speed of the ball can be calculated using the formula v = ωr, where ω is the angular velocity and r is the radius of the circle.

The centripetal acceleration can also be expressed as a = ω²r. Solving for ω, we get ω = √(a/r) = √(12.0 m/s² / 3.0 m) = 2.45 rad/s. Therefore, the tangential speed of the ball is v = ωr = (2.45 rad/s) x (3.0 m) = 7.35 m/s.

c. The period of frequency is the time taken for one complete revolution or cycle. It can be calculated using the formula T = 2π/ω, where ω is the angular velocity. Substituting the value of ω calculated in part (b), we get T = 2π/2.45 rad/s = 2.56 s.
