Explanation:

When an object is placed inside the focal point of a concave mirror, the image formed will be virtual, upright, and magnified.

This occurs because the light rays reflecting off the mirror diverge and never intersect on the real side of the mirror. Instead, they appear to converge on the virtual side, behind the mirror.

As a result, the image of the object will be farther from the observer than the object itself. The observer will see the image behind the mirror, which is not the actual position of the object, making it appear more distant than it truly is.

Typos and irrelevant parts of the question should be ignored.What is thermodynamics?Thermodynamics is the study of how energy is transferred between systems and surroundings. It includes topics such as heat transfer, work, and temperature. In order to understand thermodynamics, it is important to understand the concept of a system and its surroundings.A system is a specific part of the universe that is being studied. The surroundings are everything else in the universe that is not part of the system. The system and surroundings are separated by a boundary.What is temperature difference?Temperature is a measure of how hot or cold a substance is. Temperature difference is the difference between the temperature of the system and the temperature of the surroundings. In thermodynamics, it is important to understand that energy tends to flow from areas of high temperature to areas of low temperature. This is known as the second law of thermodynamics.The temperature difference between the system and surroundings is infinitesimally small because the system and surroundings are in thermal equilibrium. This means that there is no net transfer of energy between the system and surroundings, and the temperature difference is zero. If the temperature difference were not infinitesimally small, then there would be a net transfer of energy between the system and surroundings. This would violate the second law of thermodynamics.
The temperature difference between the system and surroundings is infinitesimally small in order to maintain a quasi-equilibrium state during a thermodynamic process. This ensures that the process occurs gradually and the system remains in equilibrium at each stage, allowing for reversible processes and accurate thermodynamic analysis.

A puck moves at 2.35 m/s in a -22° angle.It is pushed for 0.215 seconds by a hockey stick, changing its velocity to 6.42 m/s in a 50.0° direction. The negative sign indicates that the puck has fallen below its initial height.

How to solve the given problem with the help of trigonometry?

To solve the problem, we need to use the equations of motion and trigonometry.

First, let's find the initial velocity components:

\(\mathrm V_{i,x} = v_i cos(\theta_i) = 2.35 cos(-22^\circ) \approx 2.216\text{ m/s}\)

\(\mathrm V_{i,y} = v_i sin(\theta_i) = 2.35 sin(-22^\circ) \approx -0.891\text{ m/s}\)

where \(v_i\) is the initial velocity and \(\theta_i\) is the initial angle in degrees.

Next, we need to find the final velocity components:

\(\mathrm V_{f,x} = v_f cos(\theta_f) = 6.42 cos(50^\circ) \approx 4.121\text{ m/s}\)

\(\mathrm V_{f,y} = v_f sin(\theta_f) = 6.42 sin(50^\circ) \approx 4.936\text{ m/s}\)

where \(v_f\) is the final velocity and \(\theta_f\) is the final angle in degrees.

The change in velocity components are:

\(\Mathrm\Delta V_x = V_{f,x} - V_{i,x} \approx 1.905\text{ m/s}\)

\($\Delta V_y = V_{f,y} - V_{i,y} \approx 5.827\text{ m/s}\)

The time of the push is t = 0.215 s.

Using the equation of motion, we can find the change in position in the y-direction:

\($\Delta y = V_{i,y} t + \frac{1}{2} a_y t^2\)

where a_y is the acceleration in the y-direction.

Since the puck is in flight, the only force acting on it is gravity, which causes an acceleration of \(-9.8 m/s^2\) in the y-direction.

Plugging in the values, we get:

\(\Delta y = (-0.891\text{ m/s})(0.215\text{ s}) + \frac{1}{2} (-9.8\text{ m/s}^2)(0.215\text{ s})^2 \approx -0.139\text{ m}\)

Note that the negative sign indicates that the puck has fallen below its initial height.

Therefore, the change in position in the y-direction is approximately 0.139 m.

The critical angle of a light ray at the interface between the material and a vacuum is 30 degrees.

To find the critical angle of a light ray at the interface between the material and a vacuum when the speed of light in the material is 0.50c, we can use Snell's Law. Snell's Law is given by:
n1 * sin(theta1) = n2 * sin(theta2)
where n1 and n2 are the indices of refraction of the two materials,
theta1 is the angle of incidence, and
theta2 is the angle of refraction.

In this case, n1 is the index of refraction of the material, n2 is the index of refraction of a vacuum (which is 1), and theta2 is the critical angle. The critical angle is the angle of incidence when the angle of refraction (theta2) is 90 degrees.

First, we need to find the index of refraction of the material. The index of refraction can be found using the formula:
n = c / v
where n is the index of refraction,
c is the speed of light in a vacuum, and
v is the speed of light in the material.

Since the speed of light in the material is given as 0.50c, we can plug this value into the formula:
n = c / (0.50c) = 1 / 0.50 = 2

Now, we can use Snell's Law to find the critical angle:
2 * sin(theta1) = 1 * sin(90)
sin(theta1) = 1/2
theta1 = arcsin(1/2)
theta1 ≈ 30 degrees

Explanation:

Because it's the most logical answer.

Answer:

28 N

Explanation:

From the question given above, we were told that 10 N force and 18 N force act in the same direction on the object.

The net force acting on the object can be obtained by simply adding both forces together since they both act on the object in the same direction. This is illustrated below:

Force 1 (F₁) = 10 N

Force 2 (F₂) = 18 N

Net force (Fₙ) =?

Fₙ = F₁ + F₂ (since they both act in the same direction)

Fₙ = 10 + 18

Fₙ = 28 N

Therefore, the net force acting on the object is 28 N.

The mass of the sample of neon gas is equal to the mass of the container, which is 47.2 g.

To solve this problem, we can use the principle of conservation of energy, assuming that no heat is exchanged with the surroundings.

We'll use the equation:

Q_neon + Q_container = 0,

where Q_neon represents the heat gained or lost by the neon gas and Q_container represents the heat gained or lost by the container.

The heat gained or lost by a substance can be calculated using the equation:

Q = mcΔT,

where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Let's calculate the heat gained or lost by the neon gas:

Q_neon = m_neon × c_neon × ΔT_neon,

where m_neon is the mass of the neon gas and c_neon is its specific heat capacity.

We need to assume that the specific heat capacity of neon gas at constant volume is approximately equal to its specific heat capacity at  constant pressure.For monatomic gases like neon, the molar specific heat capacity at constant volume (Cv) is (3/2)R, where R is the molar gas constant. The molar specific heat capacity at constant pressure (Cp) is (5/2)R.

Since we have the molar mass of neon, we can calculate the molar gas constant (R) as follows:

R = 8.314 J/(mol·K).

The mass of neon gas can be determined using its molar mass (M) and the number of moles (n):

m_neon = n × M.

The number of moles can be obtained from the ideal gas law:

PV = nRT,

where P is the pressure, V is the volume, T is the temperature, and R is the molar gas constant.

In this case, we are assuming no change in the volume of the container, so the volume factor cancels out. Therefore, we don't need to consider the volume in our calculations.

Now let's calculate the heat gained or lost by the container:

Q_container = m_container × c_container × ΔT_container,

where m_container is the mass of the container and c_container is its specific heat capacity.

Since the final temperature is the same as the initial temperature of the container, ΔT_container is zero, and there is no heat gained or lost by the container.

Returning to the conservation of energy equation:

Q_neon + Q_container = 0,

we have:

Q_neon + 0 = 0,

Q_neon = 0.

Since Q_neon is zero, it means that no heat is gained or lost by the neon gas. This implies that the initial and final temperatures of the neon gas are the same, 13.0°C.

Now, let's calculate the mass of the neon gas:

m_neon = n × M,

where n is the number of moles.

To find the number of moles, we can use the ideal gas law:

PV = nRT,

where P is the pressure and R is the molar gas constant.

Given that no pressure is specified in the problem, we assume that the pressure remains constant. Therefore, the number of moles (n) and the mass of the neon gas (m_neon) remain the same.

In conclusion, the mass of the sample of neon gas is equal to the mass of the container, which is 47.2 g.
