The process of charging a conductor by bringing it near another charged object and then grounding the conductor is called Induction. The correct option is C.

The process described, in which a conductor is charged by bringing it near another charged object and then grounding the conductor, is known as induction. Induction involves the redistribution of charges within the conductor without direct contact between the two objects.

Here's how the process works: When a charged object is brought close to the conductor, the charges in the conductor are rearranged.

This occurs due to the electric field of the charged object influencing the distribution of charges within the conductor. However, the conductor itself remains electrically neutral overall.

If the conductor is then grounded, allowing it to make contact with the Earth or a large reservoir of charge, any excess charges in the conductor are neutralized or redistributed, resulting in the conductor becoming charged with the opposite polarity to that of the inducing object.

Therefore, the correct term for this process is c, induction.

The canoe accelerates with a constant acceleration of 0.45 m/s² away from the shore, increasing its velocity. The canoe's speed after paddling 32 meters is about 5.37 m/s.

To determine the canoe's velocity after traveling 32 m with an acceleration of 0.45 m/s², we can use the kinematic equation:

v² = u² + 2as

where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement.

In this case, the initial velocity (u) is assumed to be zero because the problem states that the canoe accelerates away from the shore. The displacement (s) is given as 32 m, and the acceleration (a) is 0.45 m/s².

Substituting the values into the equation, we have:

v² = 0² + 2 * 0.45 m/s² * 32 m

v² = 0 + 28.8 m²/s²

v ≈ √28.8 m/s

v ≈ 5.37 m/s

Therefore, the canoe's velocity after traveling 32 m with an acceleration of 0.45 m/s² is approximately 5.37 m/s.

in conclusion, The canoe's velocity is determined by its initial velocity, the acceleration it undergoes, and the distance it travels. In this case, since the initial velocity is zero, the final velocity is solely determined by the product of the acceleration and the displacement.

As the canoe accelerates away from the shore with a constant acceleration of 0.45 m/s², its velocity increases. After traveling 32 m, the canoe's velocity is approximately 5.37 m/s.

Two identical books are placed on a bookshelf. Book 1 is on a shelf one meter above the floor and Book 2 is on a shelf two meters above the floor.

Which statement best compares the potential energy of the books.

A) Book 2 has twice as much potential energy as Book 1

B) Book 1 has twice as much potential energy as book 2

Answer:

A: Book 2 has twice as much potential energy as Book 1

Explanation:

Formula for potential energy is;

P.E = mgh

Where;

m is mass

g is acceleration due to gravity

h is height

Now, they are identical books and thus will have the same mass while acceleration due to gravity remains constant.

For book 1 which is 1 metre above the floor;

P.E = mg × 1

P.E = mg

For book 2 which is 2 metres above the floor;

P.E = mg × 2

P.E = 2mg

We can see that potential energy for book 2 is twice that of book 1.

Thus,option A is correct.

Answer:

The speed of the flow of water in the river is 4 m/s.

Explanation:

Given that,

Speed of man = 5 m/s

If this man swims crosses a specific river his speed is 3 m/s.

If he takes the minimum time to cross the river

Let the speed of flow of water be \(v_{r}\)

We need to calculate the speed of the flow of water in the river

Using formula for velocity

\(v_{rs}^2=v_{r}^2+v_{s}^2\)

\(v_{r}^2=v_{rs}^2-v_{s}^2\)

Where, \(v_{s}\) = velocity of swimmer

\(v_{sr}\) = relative velocity

\(v_{r}\) = velocity of river

Put the value into the formula

\(v_{r}^2=5^2-3^2}\)

\(v_{r}=\sqrt{5^2-3^2}\)

\(v_{r}=4\ m/s\)

Hence, The speed of the flow of water in the river is 4 m/s.

The two possible angles that he can throw the ball is 13.1⁰ and 77⁰.

The time in air for each angle are 0.92 seconds and 4 seconds.

The range of a projectile is the maximum horizontal displacement of the projectile.

Mathematically, the range of a projectile is given as;

R = [u² sin(2θ)]/g

sin(2θ) = (18 x 9.8)/(20²)

sin(2θ) = 0.441

2θ = arc sin(0.441)

2θ = 26.2⁰

θ = (26.2⁰)/2 = 13.1⁰

θ' = 90 - 13.1⁰ ≈ 77⁰

R = Vₓt

t = R/Vₓ

The direction of the net electric field at the origin due to these two point charges is 77.4°.

The physical field that encircles electrically charged particles and exerts force on all other charged particles with in field, either attracting or repelling them, is known as an electric field. It also describes the physical field of a system of charged particles. Electric charges and time-varying electric currents are the basis of electric fields. The electromagnetic field, one of the four basic interactions of nature, manifests itself in both electric and magnetic fields.

Electric fields play a significant role in many branches of physics and are used in electrical engineering. For instance, in atomic physics and chemistry, the electric field acts as the attractive force that holds the atomic nucleus and electrons together in atoms. It is also the force that causes atoms to bond chemically to form molecules.

Part A

The equation for the magnitude of the electric field at the origin for both points is given by:

\($E=\frac{k q}{r^2}\)

\($$Substituting in the appropriate values for each charge yields$$E_1=\frac{\left(8.99 \times 10^9\right)\left(4 \times 10^{-9}\right)}{\left.\sqrt{0.6^2+0.8^2}\right)^2}=35.9 \mathrm{~N} / \mathrm{C}$$The charge is located at an angle of $\theta=\tan ^{-1} \frac{0.8}{0.6}=53.1^{\circ}$ this means $\mathrm{i}$ and $\mathrm{j}$ components for $E_1$$$\begin{aligned}& E_{1 i}=35.9 \cos 53.1=21.5 i \mathrm{~N} / \mathrm{C} \\& E_{1 j}=35.9 \sin 53.1=28.7 j \mathrm{~N} / \mathrm{C}\end{aligned}\)

A parallel-plate capacitor with circular plates of 10 cm radius and a separation of 120 mm has a capacitance of 9.27 pF.

The capacitance of a parallel-plate capacitor is directly proportional to the area of the plates and inversely proportional to the separation between the plates. This is because the larger the area of the plates, the more charge can be stored on them.

The smaller the separation between the plates, the stronger the electric field between them, and the more charge can be stored. In this case, the capacitance is relatively small because the separation between the plates is relatively large. If the plates were brought closer together, the capacitance would increase.

This can be calculated using the following formula:

C = (epsilon_0 * A) / d

where:

* C is the capacitance in Farads

* epsilon_0 is the permittivity of free space (8.85 x 10^-12 F/m)

* A is the area of the plates in square meters

* d is the separation between the plates in meters

In this case, the area of the plates is pi * (10 cm)^2 = 78.54 square centimeters, and the separation between the plates is 0.12 m. Substituting these values into the formula, we get:

C = (8.85 x 10^-12 F/m * 78.54 square centimeters) / 0.12 m = 9.27 pF

The given differential equation is:

dQ/dt = -0.04Q

where Q is the quantity of the toxic chemical and t is time in years.

To solve this differential equation, we can use separation of variables:

dQ/Q = -0.04 dt

Integrating both sides, we get:

ln|Q| = -0.04t + C

where C is the constant of integration. To find the value of C, we can use the initial condition that the initial leak is 60 kg:

ln|60| = -0.04(0) + C

C = ln|60|

Substituting this value of C back into the general solution, we get:

ln|Q| = -0.04t + ln|60|

Simplifying, we get:

ln|Q/60| = -0.04t

Exponentiating both sides, we get:

Q/60 = e^(-0.04t)

Multiplying both sides by 60, we get the final solution:

Q = 60e^(-0.04t)

Therefore, the quantity of the toxic chemical present at any time t (measured in years) after the initial leak is:

The time it takes for the jet to reach landing speed is approximately 0.136 hours which is approximately 489 seconds

The landing speed is approximately 466.365 km/hr

Explanation:

The given parameters are;

The initial cruising speed of the jet = Mach 0.79 = 844 km/hr

The rate of speed reduction in the last 89 km = -2780 km/hr²

The distance it  takes the jet to reduce its speed for landing = 89 km

Given the above information,  we make use of the following equation of motion;

s = u·t - 1/2·a·t²

v² = u² - 2·a·s

Where;

s = The distance over which the acceleration (deceleration) is applied = 89 km

u = The initial velocity = 844 km/hr

t = The time taken for the accelerating/decelerating motion

v = The final velocity (landing speed)

Substituting the values gives;

v² = 844² - 2·(2780)·89 = 217496

v = √217496 = 466.365 km/hr

v ≈ 466.365 km/hr

Therefore, the landing speed, v  ≈ 466.365 km/hr

The time it takes is given by the equation, v = u - a·t

Therefore;

t = (u - v)/a = (844 - 466.365)/2780 ≈ 0.136 hours

The time it takes for the jet to reach landing speed ≈ 0.136 hours

From, s = u·t - 1/2·a·t², we have

89 = 844·t - 1/2 × 2780 × t²

89 = 844·t - 1390 × t²

1390 × t² - 844·t + 89 = 0

Solving with an online application gives;

t = 211/695 + (√(27187/2))/695 = 0.4715 hours or t = 211/695 - (√(27187/2))/695 = 0.136 hours

We note that the second time is for the time it will take the jet to get back to 89 km after reaching a speed of 0

Therefore, the correct time is t = 0.136 hours

The time it takes for the jet to reach landing speed ≈ 0.136 hours

The two complementary forces that keep the sun from blowing itself up are gravity and nuclear fusion.

Gravity is the force that exists between any two masses, any two bodies, any two particles. It is the force that attracts a body towards the center of the Earth, or towards any other physical body with mass.

Nuclear fusion is the process by which two atomic nuclei join together to form a heavier nucleus. This process releases energy, as per the famous equation,

E = mc²,

where E is the energy released, m is the mass that gets converted to energy, and c is the speed of light. The sun and other stars release energy through nuclear fusion.

Gravity is the force that attracts all the particles of matter together in the sun's core. It keeps the nuclear fuel together and squeezes the matter so tightly that the temperature and pressure in the core are sufficient to make nuclear fusion reactions occur.

The energy released during nuclear fusion reactions in the sun's core is what keeps the sun shining and stable. The outward pressure from the energy released in nuclear fusion is balanced by the inward force of gravity. The sun stays in a stable equilibrium state where these two forces are balanced, preventing it from blowing itself apart.

The required mass rate of change (Δm/Δt) of the space probe to achieve an upward acceleration of 2.50 m/\(s^2\) is approximately 10.1351 kg/s.

To determine the required mass rate of change (Δm/Δt) of the space probe, we can use the generalized form of Newton's Second Law, which states that the force acting on an object is equal to its mass multiplied by its acceleration.

The force acting on the space probe is given by F = (Δm/Δt) * v, where v is the velocity at which the fuel is ejected.

The upward acceleration of the space probe is given as 2.50 m/\(s^2\).

Using the equation F = m * a, where m is the mass of the space probe and a is the upward acceleration, we have:

(Δm/Δt) * v = m * a

Rearranging the equation, we can solve for Δm/Δt:

Δm/Δt = (m * a) / v

Substituting the given values, we have:

Δm/Δt = (150,000 kg * 2.50 m/\(s^2\)) / 37,000 m/s

Calculating this expression, we find:

Δm/Δt ≈ 10.1351 kg/s
