I am going to assume that the rider starts at rest. Using the equation for kinetic energy, the answer would be equivalent to \(\frac{1}{2} (100)(11)^{2}\). The final answer would be 50 N.

The acceleration of the eraser is 169.19 m/s².

A body travelling in a circle has centripetal acceleration. Due to the fact that velocity is a vector quantity (i.e., it has both a magnitude and a direction), when a body travels in a circle, its direction is continually changing, which causes a change in velocity, which results in an acceleration.

Given that angular velocity of the eraser: ω = 127 rpm

= 126×2π/60 radian/second

= 13.2 radian/second.

radius of the circle: r = 0.974 meter.

Hence, its centripetal acceleration is = ω²r

= 13.2×13.2×0.974 m/s²

=169.19 m/s².

The efficiency of the system of the levers is  122%.

We have to note that the efficiency is the ratio of the work out put to the work out put multiplied by 100. In this case, we are told that a lift is used to carry boxes to the top floor of a hotel 20 m high. A total weight of 100 kg of boxes was carried up in 20 seconds. and that  the useful output of the engine driving the lift mechanism is 1.2 kilowatt.

Work input = 100 Kg * 9.8 m/s^2* 20 m = 19600 J

Work output = 1.2 kilowatt * 10^3 * 20 = 24000 J

Then we have;

Efficiency = Work out put/ Work input * 100

= 24000/19600 * 100

The angular acceleration of the pulley can be determined by considering the forces acting on the system and the moment of inertia of the pulley. Based on the task, the angular acceleration of the pulley is 2.45 rad/\(s^{2}\).

The angular acceleration of the pulley can be determined by considering the forces acting on the system and the moment of inertia of the pulley. The net force acting on the system is given by the weight of the hanging mass, which creates a tension in the rope that is transferred to the pulley. The tension in the rope produces a torque on the pulley, given by:

The tension in the rope produces a torque on the pulley, given by:

τ = T * r

where,

T = the tension in the rope

r = the radius of the pulley.

The net torque on the pulley can be used to determine its angular acceleration, given by:

α = τ / I

where,

I is the moment of inertia of the pulley, given by:

I = (1/2) * m * \(r^{2}\) + m * \(r^{2}\)

where m is the mass of the pulley.

Substituting the values, we get:

α = (T * r) / ((1/2) * m *  \(r^{2}\) + m *  \(r^{2}\))

A concave mirror is a mirror with a curved, inwardly facing surface. When an object is placed in front of a concave mirror, the mirror will form an image of the object. The nature of the image formed depends on the position of the object relative to the mirror.

To find the image distance from the pole of the mirror, you can use the mirror equation:

1/image distance + 1/object distance

= 1/focal length.

If the object is X distance from the pole of the mirror, you can substitute this value for the object distance in the mirror equation to find the image distance.

The relationship between the object distance, image distance, and focal length of a concave mirror can be expressed using the mirror equation:

1/image distance + 1/object distance

= 1/focal length.

This equation tells us that the sum of the reciprocals of the object distance and image distance is equal to the reciprocal of the focal length.

No, the sun cannot explain global warming. Global warming is a phenomenon in which the temperature of the Earth's surface and atmosphere is rising continuously due to human activities such as deforestation, burning of fossil fuels, and industrialization.

This increase in temperature cannot be explained only by an increase in solar radiation.There are several factors which contribute to global warming, including greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the Earth's atmosphere, which causes the planet's temperature to rise. The sun's radiation does contribute to global warming, but it is not the main cause.

i) To calculate the increase in solar radiation that would cause the Earth to warm up by 1 K, we can use the following formula:ΔS = ΔT / αWhere ΔS is the increase in solar constant, ΔT is the increase in temperature, and α is the Earth's albedo (reflectivity).α = 0.30 is the standard value used for the Earth's albedo.ΔS = ΔT / αΔS = 1 K / 0.30ΔS = 3.33 W/m2So, to explain the increase in temperature of 1 K over the last hundred years, the solar constant would need to increase by 3.33 W/m2.

ii) The observed fluctuation of the solar constant over the past 400 years has been around 0.1% to 0.2%. This is much smaller than the 3.33 W/m2 required to explain the increase in temperature of 1 K over the last hundred years. Therefore, it is unlikely that the sun is the main cause of global warming.

The sun cannot explain global warming. While the sun's radiation does contribute to global warming, it is not the main cause. The main cause of global warming is human activities, particularly the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.

The mass and magnitude of the second particle are calculated below.

The initial velocity of an object is its velocity prior to the effect of acceleration, which causes the change. The velocity will be the final velocity after accelerating the object for some time. When a particle moves at a constant speed, it can be accelerated. When a point object moves in a horizontal circular path at a constant speed, the direction of its velocity vector changes over time. It means that in a uniform circular motion, the object's velocity vector changes over time.

Distance between the charges, r = 3.2 × \(10^{-3}\)m

initial acceleration of first particle, \(a_{1}\) = 7m / \(s^{2}\)

Initial acceleration of second particle, \(a_{2}\) = 9.0m / \(s^{2}\)

Mass of first particle, \(m_{1}\) = 6.3 × \(10^{-7}\)kg

Mas of second particle, m₂ = ?

a) Since, \(F_{1}=F_{2}\)

∴ \(m_{1}a_{1} = m_{2}a_{2}\)

mass of second particle-\(m_{2}\) =\(\frac{m_{1}\times a_{1}}{a_{2}}\)

= \(\frac{6.3\times10^{-7}\times7.0}{9.0}\)

=4.9 × \(10^{-7}\)Kg

b)As, \(F_{1} = F_{2}\)

       = \(\frac{q_{1}q_{2}}{4\pi E_{0}r^{2}}\) = \(m_{1}a_{1}\)

       = 6.3 × \(10^{-7} \times\) 7.0

Among the given options, the correct statement about the combination of four unequal resistors connected in parallel is that the equivalent resistance is less than that of the smallest resistor.

In a parallel combination, the voltage across each resistor is the same and the current is divided among the resistors. Therefore, the total current through the combination is equal to the sum of the currents through the individual resistors. According to Ohm's Law, the current through a resistor is inversely proportional to its resistance.

Therefore, the resistor with the smallest resistance will allow the most current to flow through it. As a result, the overall resistance of the combination will be less than that of the smallest resistor.
