To reach a maximum height of 200 meters when thrown upward from a height of 2 meters, the object must have an initial velocity of approximately 62.32 meters per second, using the kinematic equation with gravity as the acceleration and neglecting air resistance.

To find the initial velocity required to reach a maximum height of 200 meters when thrown up from an initial height of 2 meters, we need to use kinematic equations that describe motion under constant acceleration. Here, the acceleration is due to gravity, which is negative because it is directed downwards. Since air resistance is neglected, the initial velocity will be the same for any object thrown up to reach the specified height.

Using the kinematic equation v^2 = u^2 + 2as, where v is the final velocity (0 m/s at maximum height), u is the initial velocity, a is the acceleration due to gravity (-9.81 m/s^2), and s is the displacement (198 meters, which is the difference between the final height and the initial height), we can solve for u. Rearranging the equation gives u = sqrt(v^2 - 2as). Substituting v = 0 m/s, a = -9.81 m/s^2, and s = 198 m, the calculation of the initial velocity can be performed:

Initial Velocity, u = sqrt(0^2 - 2*(-9.81 m/s^2)*198 m) = sqrt(3883.56 m^2/s^2) = 62.32 m/s.

The initial velocity required is therefore approximately 62.32 meters per second.

Answer:  The momentum of the system after the collision is 0.2 kg m/s.

Explanation:

According to the conservation of momentum, the total momentum of the system before the collision is same the total momentum of the system after the collision in an isolated system.

[tex]m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2}[/tex]

Here, m_{1},m_{2} are the first and second object, v_{1},v_{2} are the initial velocities of the first and second objects and u_{1},u_{2} are the final velocities of the first and the second objects.

Use the formula of the conservation of the momentum.

[tex]m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2}[/tex]

Put m_{1}=0.6 kg, m_{2}=0.5 kg, v_{1}=0.5 m/s and v_{2}=-0.2 m/s.

[tex]m_{1}u_{1}+m_{2}u_{2}=(0.6)(0.5)+(0.5)(-0.2)[/tex]

[tex][tex]m_{1}u_{1}+m_{2}u_{2}[/tex]= 0.2 kg m/s[/tex]

Therefore, the momentum of the system after the collision is 0.2 kg m/s.

Areas near oceans have milder climates than areas in the interior of continents due to the great storage capacity of water.

Areas near oceans have milder climates than areas in the interior of continents because of the great storage capacity of water. Water is able to absorb a tremendous amount of energy with very little resulting temperature change, which leads to more moderate temperatures in coastal areas. The oceans collect and store vast amounts of solar energy and transport that heat with their currents, resulting in smaller temperature variations from day to night and from winter to summer.

Among these 4 forces, the only force acting on the plane at a distance is weight.

In fact, weight is due to gravity, which is a non-contact force (it acts also from a distance). All the other forces, instead, are due to the contact between the plane (or parts of it) with the surrounding air: without the air, all the other 3 forces (thrust, lift, drag) would not be present, while weight would be always present.

C. DC motor

Explanation:

DC motor is an electrical machine which converts DC electrical current into mechanical energy. Generally DC motors work on the forces produced by magnetic fields. Here(in the given diagram) stater is made from the permanent magnets in which magnetic rotor rotates. The rotating magnetic field interacts with stater's permanent magnet and generate torque which rotates armature.

Answer: 4

The mechanical advantage is the ratio of the force exerted  by the object to the force applied to do work on it.

Here, Jeff tried to lift a rock weighing 600 pounds by wedging board under the rock. Jeff who weighs 150 pounds uses all his weight to exert force on lever and lift rock.

Mechanical advantage, [tex]M.A.=\frac{weight\hspace{1mm}of\hspace{1 mm}rock}{weight\hspace{1mm}of\hspace{1 mm}Jeff}=\frac{600 pounds}{150 pounds}=4.[/tex]

Compression waves and water waves share similarities as longitudinal waves that transfer energy through a medium, but they differ in their propagation medium and oscillation nature.

Explanation:

Compression waves and water waves are both types of longitudinal waves that involve oscillations. They share the common characteristic of transmitting energy through a medium. However, they differ in the medium through which they travel and the nature of their oscillations.

Final answer:

The mantle makes up 70% of the Earth's total volume, which is the largest layer of the interior structure of the Earth. It accounts for 82.5% of the Earth's volume, with the core and crust making up the rest.

Explanation:

The component that makes up 70% of the Earth's total volume is the mantle. The mantle is predominantly composed of silicate rock and is situated between the Earth's crust and core. It comprises approximately 82.5% of the Earth's volume, making it the largest layer of the Earth's interior. The core is the second-largest layer, accounting for 16.1% of the volume, while the crust is the thinnest layer, making up only 1.4%. It is important to note that although water covers approximately 71% of the Earth's surface, it is not what comprises the largest volume of Earth's internal structure, as might be mistakenly inferred.

Final answer:

The experiment likely demonstrates heat transfer by conduction as heat is transferred through physical contact. Convection and radiation are other forms of heat transfer explained in the context of the experiment.

Explanation:

Kim's experiment most likely demonstrates **heat transfer by conduction.** Conduction is the transfer of heat through stationary matter by physical contact. In this experiment, the heat from the hot water is transferred to the iron rod, causing the wax on one end to melt due to the direct contact.

Convection involves the heat transfer by the macroscopic movement of a fluid, like in a forced-air furnace or weather systems. Radiation occurs when electromagnetic radiation is emitted or absorbed, like the warming of Earth by the Sun or thermal radiation from the human body.

When a positively charged particle enters a magnetic field, it experiences a force perpendicular to its velocity and the magnetic field, causing it to follow a curved path, typically resulting in circular or spiral motion.

If a positively charged particle moves into a magnetic field traveling in a straight line, its motion will change according to the Lorentz force law. When a positively charged particle enters a magnetic field, it experiences a force known as the Lorentz force that acts perpendicular to both the magnetic field and the velocity of the particle. As a result, the particle's path will bend and it will undergo circular motion or spiral along the field lines, depending on multiple factors such as the angle at which it enters the field.

For instance, if a positively charged particle is moving to the left and enters a magnetic field pointing towards the top of the page, the magnetic force acting on it will be directed into the page, causing it to deviate from its straight-line path. Similarly, if the particle is moving to the right, the force will be directed out of the page. If the magnetic field is uniform, the particle follows a curved path and may complete a full circle, with the radius of this circle determined by the particle's charge, velocity, and the magnetic field strength.

The direction of force and hence the subsequent motion of a positive particle differs from that of a negative particle due to their opposite charges. Different velocities or magnetic field strengths will result in different path curvatures, hence to measure the mass of a charged particle, one might need to observe its motion under various conditions. Doubling the charge or the magnetic field strength will affect the radius of the circular path, while doubling the velocity will change the shape of the path.

For neutral particles, there is no direct interaction with the magnetic field, and as such, their paths remain unaffected. To summarize, a positively charged particle's motion in a magnetic field results in a curved path that depends on its charge, velocity, magnetic field strength, and mass.

The work function of a metal is the minimum energy required to remove an electron from the metal surface. The energy can be calculated with the given light wavelength, but additional data is needed to find the specific work function of aluminium.

The work function of a metal is the minimum amount of energy required to remove an electron from the surface of the metal. This is a concept from the field of physics known as the photoelectric effect, commonly associated with Albert Einstein.

The energy of incident photons can be calculated using the formula E = hc/λ, where E is the energy, h is the Planck's constant, c is the speed of light, and λ is the wavelength of the light. The maximum kinetic energy of the ejected electrons, on the other hand, is given by the equation KE = E - W, where E is the energy of the incident photon and W is the work function of the metal.

Consequently, to find the work function or binding energy of a particular material, you can rearrange the equation into W = E - KE. For this specific problem though, more information would be necessary such as the kinetic energy of the ejected electrons to pinpoint the work function of aluminium metal in kj/mol specifically.

When a plastic rod is rubbed against a wool shirt and acquires a charge of -4.9 µC, it means that about 3.06 × 10¹³ electrons have been transferred from the shirt to the rod.

The plastic rod acquires a charge of -4.9 µC after being rubbed against a wool shirt. This negative charge means that electrons have been transferred from the wool shirt to the plastic rod. To determine the exact number of electrons transferred, we can use the following formula that connects the amount of charge and the number of electrons:

Q = n × qe

where 'Q' is the total charge, 'n' is the number of electrons, and 'qe' is the elementary charge, which is 1.6 × 10⁻¹⁹ C. We solve this equation for 'n':

n = Q / qe

When we put the values in, we get:

n = -4.9 µC / 1.6 × 10⁻¹⁹ C

To convert microcoulombs (µC) to coulombs (C), we must multiply by 10⁻⁶. Hence, the calculation becomes:

n = -4.9 × 10⁻⁶ C / 1.6 ×10⁻¹⁹ C = approximately 3.06 × 10¹³ electrons

So, roughly 3.06 × 10¹³ electrons are transferred from the wool shirt to the plastic rod.
