A boy ties a stone to the end of a string which he then whirls above his head round a circular path of radius 2 metre. If the stone makes 10 oscillations in 4 seconds, calculate the angular and linear speed of the stone.

If you are driving an oscillatory system at a certain frequency, but the amplitude is much smaller than it could be, you can be certain that the driving frequency is not matched to the natural frequency of the oscillatory system.

When an oscillatory system is driven at its natural frequency, it undergoes resonance, resulting in maximum amplitude. However, if the driving frequency is not matched to the natural frequency, the system will not respond with a large amplitude. Instead, the amplitude will be smaller.
In such a case, the oscillatory system is not efficiently absorbing energy from the driving force, and the motion becomes less pronounced. This indicates that the driving frequency does not coincide with the natural frequency of the system, leading to a suboptimal response and a smaller amplitude.

To express t1 (the first term) in terms of S1 (the sum of the first term), we can use the formula for the nth term of an arithmetic series:

t_n = a + (n-1) * d

Here, t_n represents the nth term, a is the first term, n is the number of terms, and d is the common difference.

In our given series, the first term is a = 3 and the common difference is d = 4. To find t1, we need to determine the value of n.

The angular acceleration at t = 3s is approximately -11.20 rad/s^2.t

To find the angular acceleration at t = 3s, we first need to determine the angular velocity (ω) at that time.

The angular velocity (ω) can be calculated using the formula:

ω = v / r

where v is the velocity and r is the radius of the circle.

Given that the radius (r) is 40.4 m, we need to find the velocity (v) at t = 3s. We can use the equation provided:

v(t) = v0 e^(-bt)

Substituting the values, we have:

v(3) = 445 e^(-0.73 * 3)

When a burning candle is covered with an inverted gas jar, it eventually stops burning due to the lack of oxygen inside the jar. The combustion process in a candle requires oxygen to sustain the chemical reaction that produces heat and light.

Initially, the burning candle consumes oxygen from the surrounding air, creating a partial vacuum inside the gas jar. As the flame continues to burn, it rapidly depletes the available oxygen within the jar. Once the oxygen concentration drops below the level necessary to sustain combustion, the flame gradually weakens and eventually extinguishes. The inverted gas jar acts as a sealed environment, preventing the entry of fresh air into the jar and limiting the supply of oxygen. As the oxygen is consumed by the flame and not replenished, the candle's fuel source becomes depleted, leading to the cessation of the burning process. In summary, the burning candle stops burning when covered with an inverted gas jar due to the depletion of oxygen inside the jar, which is essential for the combustion process.

The common velocity of masses m and M after the impact is v = mv / sqrt(m (m + M)). A pendulum consists of a mass m hanging at the bottom end of a massless rod of length l, which has a frictionless pivot at its top end. A mass m, moving as shown in the figure with velocity v impacts m and becomes embedded.

The given figure shows the before and after impact of two masses m and M with velocities v and 0, respectively, where mass M is hanging with the help of a rod and performing simple harmonic motion. Therefore, the given system of masses is an example of an inelastic collision. As per the principle of conservation of linear momentum in physics, the momentum of a system is conserved if the net external force acting on it is zero. As the given system of masses has no external force acting on it, its momentum is conserved.

The initial momentum of the system can be calculated as:pi = mv + 0Since mass M is at rest, its initial momentum is zero. Therefore, the total initial momentum of the system ispi = mv. The final momentum of the system can be calculated as:pf = (m + M)V. Here, V is the common velocity of masses m and M after the impact, which can be calculated using the principle of conservation of mechanical energy.

As the given system of masses is an example of an inelastic collision, some energy is lost during the impact due to deformation of the masses. Therefore, the conservation of mechanical energy can be written as:

1/2 mv² = (1/2) (m + M) V²

Solving for V, we get:V² = mv² / (m + M)V = v * sqrt(m / (m + M))

Therefore, the final momentum of the system can be calculated as:pf = (m + M) v * sqrt(m / (m + M)) = v * sqrt(m (m + M))

Therefore, applying the principle of conservation of linear momentum, we have:pi = pfmv = v * sqrt(m (m + M))v = mv / sqrt(m (m + M))

The model that best describes how gravity causes star formation is the gravitational collapse model. According to this model, stars form from the gravitational collapse of dense regions within interstellar clouds of gas and dust.

The process begins with a molecular cloud, which is a large cloud of gas and dust in space. Within these molecular clouds, there are regions that are denser than their surroundings, often referred to as dense cores or protostellar cores. These dense cores can contain several times the mass of the Sun.

Under the influence of gravity, the dense core begins to collapse inward. As the core collapses, it becomes denser and hotter due to the increasing pressure. The gravitational energy is converted into thermal energy, raising the temperature and causing the core to heat up.

As the temperature rises, nuclear fusion reactions start to occur at the core's center. These fusion reactions convert hydrogen into helium, releasing enormous amounts of energy in the form of light and heat. This marks the birth of a star, as it begins to emit its own light and heat.

Gravity plays a crucial role throughout this process, providing the force necessary to overcome the outward pressure and hold the collapsing material together. The gravitational collapse model explains how the force of gravity initiates the collapse of interstellar clouds, leading to the formation of stars.

It is important to note that other factors, such as the presence of magnetic fields and turbulence within the cloud, also influence the star formation process. However, gravity is the primary driving force behind the initial collapse and subsequent formation of stars.

If heavier cars were used, the barricade would need to be designed to absorb more kinetic energy. In order to design a barricade that can absorb more kinetic energy from heavier cars, the design of the barricade must be modified. The key to designing a barricade that can absorb more kinetic energy is to use a material that can do so.

In addition, the barricade would need to be designed in such a way that it would be able to absorb as much kinetic energy as possible. One way to do this is to make the barricade thicker and heavier. This would increase its mass, which would increase the amount of kinetic energy that it could absorb. The design of the barricade would also need to take into account the work that would be required to stop the car.

The work required to stop a car is directly proportional to the kinetic energy of the car. Therefore, in order to stop a heavier car, more work would need to be done. In order to minimize the work required to stop the car, the barricade would need to be designed in such a way that it can absorb the kinetic energy of the car with minimal work.

V_x = V_initial * cos(angle)

V_x = 4.22 m/s * cos(63.0°)

V_x ≈ 1.834 m/s

Using the equation for distance traveled horizontally:

distance = V_x * t

distance = 1.834 m/s * 0.376 s

distance ≈ 0.689 m

Therefore, the grasshopper lands approximately 0.689 meters away horizontally from its initial position.

Inertia refers to the natural tendency of every object to resist any change in either speed or direction. Every object tends to maintain its state of motion until an external force acts on it.

Inertia is an essential concept in physics, and it can be observed in everyday life. Here is how you can observe inertia in your everyday life:

When you are in a moving car, and the driver suddenly stops, your body tends to move forward. This is because of inertia. Your body is already in motion, and when the car stops, your body tends to keep moving in the same direction. The seatbelt helps to prevent this movement by exerting a force on your body in the opposite direction.

When you are on a merry-go-round and it starts spinning, you tend to feel a force pushing you away from the center of the ride. This is also due to inertia. Your body is already in motion, and when the ride starts spinning, your body tends to keep moving in the same direction. The force that pushes you away from the center of the ride is known as the centrifugal force.

When you are playing a game of pool, and you hit the cue ball, it tends to keep moving until it comes into contact with another ball or hits the wall of the table. This is also due to inertia. The cue ball is already in motion, and it tends to maintain its state of motion until it comes into contact with another object or hits the wall of the table.

These are just a few examples of how you can observe inertia in your everyday life.

The time period of the pendulum will remain the same, which is 4 seconds in this case.

The time period of a simple pendulum is affected by its length and the acceleration due to gravity. However, it is independent of the amplitude of the pendulum swing. Therefore, increasing the amplitude of a simple pendulum by 4 times while keeping all other factors the same will not affect its time period. So, the time period of the pendulum will remain the same, which is 4 seconds in this case. The time period of a simple pendulum depends only on the length of the pendulum and the acceleration due to gravity, not on the amplitude of its swing.
