Answer:

D is the answer. Force can change the shape and size of an object.

The minimum amount of following time needed to create an open front zone is 3 seconds.

An open front zone is a space in front of your vehicle that allows you to see and react to potential hazards. To create an open front zone, you need to have a minimum of 3 seconds of following time between you and the vehicle in front of you.

This means that you should be able to count at least 3 seconds from the time the vehicle in front of you passes a fixed object until your vehicle passes the same object.

Having a 3-second following distance gives you enough time to react to sudden changes in traffic and avoid collisions. It also helps you maintain a safe speed and avoid tailgating, which is a common cause of accidents. In adverse weather conditions, such as rain or snow, it is recommended to increase the following distance to at least 4 seconds to allow for the reduced visibility and longer stopping distance.

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.

If a meteor with a 20 m in diameter impacts Earth on land, approximately the crater will be 200-400m in diameter long.

The size of the crater created by a meteorite impact depends on several factors, such as the composition of the meteorite and the density of the material it impacts. Generally speaking, a 20 m in diameter meteorite would create a crater with a diameter between 200 and 400m. A few meters to several hundred meters can make up the crater's depth.  A crater will most likely be created at the point of impact when a meteor impacts a planet. The size of the crater will increase as the object moves faster and becomes larger or heavier. The biggest predictors of impact crater size are the meteor's mass and velocity.

Explanation:

The maximum charge that can be placed on the capacitor before the charge arcs is 23.7 nano-coulombs.

The maximum charge that can be placed on a capacitor before the charge arcs can be calculated using the formula

Q = εAEd,

where Q is the charge, ε is the permittivity of free space, A is the area of the plates, E is the electric field, and d is the distance between the plates. Since we are given the area of the plates and the electric field, we can plug these values into the formula and solve for Q.
First, we need to convert the area of the plates from cm2 to m2:
A = 8.9 cm2

A = 8.9 x 10-4 m2
Next, we can plug the values into the formula:
Q = (8.85 x 10-12 F/m)(8.9 x 10-4 m2)(3.0 x 106 V/m)
Q = 2.37 x 10-8 C
Finally, we can convert the charge from coulombs to nano-coulombs:
Q = 2.37 x 10-8 C x (109 nC/C)

Q = 23.7 nC

The fact that a thermometer "takes its own temperature" illustrates A) thermal equilibrium. When a thermometer is placed in contact with an object or substance, the transfer of heat occurs between the thermometer and the substance until they reach the same temperature.

This state, where no net heat transfer occurs, is known as thermal equilibrium. The thermometer then displays the temperature based on the equilibrium it has reached with the substance being measured. This process demonstrates the concept of thermal equilibrium rather than energy conservation, the difference between heat and thermal energy, or the constant motion of molecules.
