The resonance frequency will remain the same if the capacitor value is doubled and, at the same time, the inductor value is halved.

The resonant frequency is a term used to describe the oscillation of a system at its natural or unforced resonance.

In an LC circuit, the resonance frequency can be determined by the following equation;

ω = 1 / √LC

Here L represents the inductor value and C illustrates the value of the capacitance.

If the capacitance is doubled, C'=2C, and the inductance is halved, L'=L/2, then;

ω = 1 / √L'C'

ω = 1 / √(L/2) × (2C) = 1 / √LC = ω

Therefore the frequency of resonance is equal to the original value.

Even your pencil and a piece of paper attract one another. You can't feel this force because the masses of the pencil and paper are so small. Even you exert a gravitational force on other objects. Because your mass is so much less than the mass of the Earth, you can't feel your gravitational force.

In simple word gravitational force is directly proportional to weight of and objects and indirectly proportional to distance.

F=G(m1 x m2) /r^2

F = force

G = gravitational constant

m_1 = mass of object 1

m_2 = mass of object 2

r = distance between centers of the masses

When a toroidal inductor with an inductance of 91.0 mh encloses a volume of 0.02m^3 then the current through the inductor is calculated as 4.91 A.

The tendency of an electrical conductor to oppose change in the electric current flowing through it is called inductance.

As we know, the magnetic energy stored in the toroid is;

U = 1/2 * L i²

Here, L -- inductance and i -- current

Average energy density, u = B²/2μ

U = u V

Here V is volume, = 0.02 m^3

Given L = 91.0 mH;  u=  55.0 j/m3 and V= 0.02 m^3

i = √2u V/L

Most substances expands when temperature increases.

At low temperatures, most substances are solids. When the temperature rises, it becomes a liquid. At higher temperatures it becomes gaseous. The process by which a solid becomes a liquid is called melting (an old term you sometimes come across is fusion).

Thermal energy is added to a material during heating. As a result, its particles accelerate and its temperature rises. The loss of thermal energy that occurs during cooling results in a decrease in temperature and slower particle motion in the cooled material. When a substance's temperature rises, its molecules expand because they have more energy and are moving faster and further apart. When a material is heated, the molecules absorb energy. The inter-molecular connections between molecules are first disrupted.

So, most substances expands when temperature increases.

It fall during the next second of time is 3hrs.

Gravitational potential energy is transformed into kinetic energy as the object is propelled out of rest and falls to Earth. Since the object is released closer to the Earth's surface, the force of gravity's acceleration is constant.

Knowing this

u = 0 m/s.

velocity after t = 1s

v = u+gt

v = 0 + 9.81 x 1s

v = 9.81 m/s

area covered in the first second

area covered in the first second = ut + 0.5 x g x t²

area covered in the first second =0 + 0.5x 9.81 x 1 = 4.90m

Let 4.90 be h

We will now use the distance traveled in the second second.

so that velocity after t = 1s

velocity after t is 1s = 1 x t+ 0.5 x g x t²

velocity after t is 1s = 9.81 x 1 + 0.5 x 9.81 x 1 = 3 x 4.90

Answer:

The elongation of the wire is approximately 4.81 x 10-³ m.

Explanation:

To find the elongation of the wire, we can use the formula:

Elongation = (Force * Length) / (Young Modulus * Cross Sectional Area)

Plugging in the given values, we have:

Elongation = (10³ N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)

We can simplify this to:

Elongation = (2500 N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)

Which simplifies to:

Elongation = (625 x 10-⁸ m³) / (1.3 x 10-¹¹ m³)

Simplifying further, we have:

Elongation = 4.81 x 10-³ m

Therefore, the elongation of the wire is approximately 4.81 x 10-³ m.

It's important to note that this is an approximate value, as the actual elongation may depend on various factors such as the temperature and the specific properties of the wire.

Free fall motion is motion in which the only force acting on the body is gravity.

The student should launch the sphere at 2v₀, for the sphere will land at approximately 1.41D, which is in the 3 point zone

The given parameter are;

The distance covered by the sphere when launched at height, H = D

The velocity with which the ball reaches D = v₀

The current available height of launcher= H/2

The available velocities = v₀, and 2v₀

Now,

From H = ut + (1/2)gt², where, initial velocity of the vertical motion of the ball, u = 0

we know;

H = (1/2)gt²

Therefore, the time it takes the ball to drop from H, t = √(2H/g)

The distance, D = v₀ × √(2H/g)

When the height is H/2, we get;

t = √(2H/(2g)) = √(H/g)

Thus, the distance covered, D₁ = v₀ × √(H/g)

Therefore, D = (√2) × v₀ × √(H/g) = (√(2))D₁

Now, D₁ = D/(√2) ≈ 0.71D

D₁ ≈ 0.71D

At speed 2v₀, we have;

D₂ = 2v₀ × √(H/g) = √2 × v2 × v₀ × √(H/g) = √2 × v₀ × √(2H/g) = √2D₁ ≈ 1.41D

D₂ ≈ 1.41D

The 2 point zone = D/2 < x < D = 0.5D < x < D (Position D₁ ≈ 0.71D is located here)

The 3 Point Zone =  D < x < 3D/2 = D < x < 1.5D (Position D₂ ≈ 1.41D is located here)

Given that at D₂, the ball lands in the 3 Point Zone, the student should launch the sphere at the speed, 2v₀, so that the ball will land at D₂ ≈ 1.41D,  which is in the 3 Point Zone

The complete question is as follows:

A group of students prepare for a robotic competition and build a robot that can launch large spheres of mass M in the horizontal direction with variable speed and from a variable vertical position and a fixed horizontal position x=0.

The robot is calibrated by adjusting the speed at which the sphere is launched and the height of the robot’s sphere launcher. Depending on where the spheres land on the ground, students earn points based on the accuracy of the robot. The robot is calibrated so that when the spheres are launched from a vertical position y=H and speed v0, they consistently land on the ground on a target that is at a position x=D. Positive directions for vector quantities are indicated in the figure.

When the students arrive at the competition, it is determined that the height of the sphere launcher can no longer be adjusted due to a mechanical malfunction. Therefore, the spheres must be launched at a vertical position of y=H2. However, the spheres may be launched at speed v0 or 2v0.

Question: In a clear response that may also contain diagrams and/or equations, describe which speed, v0 or 2v0, the students should launch the sphere at so that they earn the maximum number of points in the competition.
