Explanation:

Answer:

Because a new shellof electronic are added to the atom at every step

The answer is False. A polarized material does not need to have a nonzero net electric charge. Polarization occurs when the positive and negative charges within a material are displaced relative to each other, creating an electric dipole moment.

This can happen in materials such as dielectrics or insulators, which do not conduct electricity. The net electric charge of a polarized material can still be zero, as the overall positive and negative charges remain balanced, but the charges are spatially separated. Polarization plays an important role in phenomena such as capacitance, dielectric constant, and polarization-induced electric fields.

The mass of the interstellar cloud is the primary factor that causes its gravitational contraction. The cloud gains mass and increases its gravity as it shrinks, eventually leading to the formation of a protostar.The correct option is a.

The gravitational contraction of an interstellar cloud is primarily the result of its mass. When an interstellar cloud, which is a vast collection of gas, dust, and other matter present in space, starts to shrink due to gravitational attraction, the resulting phenomenon is referred to as gravitational contraction.

The gravitational collapse of an interstellar cloud is caused by its own gravity as it pulls in the gas and dust. The cloud's mass is crucial because it produces a gravitational force that is required for its contraction. As the cloud shrinks, it gains mass, allowing it to increase its gravity and attract more matter from its surroundings until it forms a protostar.

:Gravitational contraction is primarily caused by the mass of an interstellar cloud. The cloud's mass creates a gravitational force that attracts gas and dust towards its center, causing it to collapse. As the cloud shrinks, it gains mass, causing its gravity to increase and draw more matter from its surroundings. This process continues until a protostar forms. Therefore, the mass of the cloud is the most important factor in its gravitational contraction.The correct option is b.

The true statement is: c. The time constant has units of time and is constant for a given circuit.

To explain further, the time constant (T) of a circuit containing a resistor (R) and a capacitor (C) is given by the product of the resistance and capacitance values: T = R * C.

The time constant has units of time (typically seconds) and remains constant for a given circuit unless the resistance or capacitance values change.

When you add another capacitor with a value of C in parallel to the first capacitor, the equivalent capacitance (C eq) of the combined capacitors becomes 2C.

To find the new time constant (T') with the added capacitor, use the same formula: T' = R * C eq.

In this case, T' = R * 2C. The new time constant will be different from the original time constant T because the equivalent capacitance has changed.

The refrigeration load for the cold-storage plant using ammonia as a refrigerant and a coefficient of performance (COP) of 3.5 is calculated to be 57.143 kW.

The coefficient of performance (COP) is defined as the ratio of the desired effect (refrigeration) to the required work input (compressor power).

In this case, the COP is given as 3.5. COP = Q/W, where Q is the refrigeration effect and W is the work input. Rearranging the equation, we can express the refrigeration effect as Q = COP * W.

The refrigeration effect is the amount of heat removed from the cold-storage space per unit time. To calculate the refrigeration load, we need to determine the heat transfer rate, which is the product of the mass flow rate of the refrigerant and the change in enthalpy between the evaporator outlet and the compressor outlet.

The change in enthalpy is given as 2000 kJ/kg - 1800 kJ/kg = 200 kJ/kg. Therefore, the heat transfer rate is 1 kg/s * 200 kJ/kg = 200 kW.

Using the COP equation, we can now calculate the work input: W = Q / COP = 200 kW / 3.5 = 57.143 kW.

Both the transverse and longitudinal waves move faster at higher temperatures.

A wave in which the motion of the particles is perpendicular to the direction of the wave propagation is referred to as a transverse wave.

Here,

As a result of the shear stress that is produced, transverse waves are frequently observed in elastic materials.

In this situation, the oscillations are caused by the displacement of the solid particles from their relaxed state in directions perpendicular to the wave's propagation.

The wave in which the particles of the medium oscillate parallel to the direction of propagation of the wave is called a longitudinal wave.

Sound waves similarly oscillate parallel to the direction of propagation, forming the compressions and rarefactions. Hence sound waves are called longitudinal waves.

The correct option is B: The tension on the aluminum wire is approximately 65 N.

To find the tension on the aluminum wire, we can use the formula for the speed of transverse waves in a string:

v = √(T/μ)

where:

v = speed of transverse waves

T = tension in the wire

μ = linear mass density (mass per unit length) = density * area

First, let's calculate the area of the aluminum wire:

Given diameter = 4.6 mm

Radius = diameter/2 = 4.6 mm / 2 = 2.3 mm = 2.3 x \(10^(^-^3^)\) m

Area = π * \(r^2\)

      = π * (2.3 x 10⁽⁻³⁾)²

      = π * (5.29 x 10⁽⁻⁶⁾)

      ≈ 1.658 x 10⁽⁻⁵⁾ m²

Now, let's calculate the linear mass density (μ):

Density of aluminum = 2700 kg/m³

Linear mass density (μ) = density * area

                       = 2700 kg/m³ * 1.658 x 10⁽⁻⁵⁾ m²

                       ≈ 0.0447 kg/m

Now, we can rearrange the formula for the speed of transverse waves to solve for tension (T):

T = μ * v²

Given v = 38 m/s and μ = 0.0447 kg/m, we can calculate T:

T = 0.0447 kg/m * (38 m/s)²

 ≈ 63.9906 N

Rounding to the nearest whole number, the tension on the wire is approximately 64 N.

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, when you push horizontally on the large crate, the crate exerts a backward force on you with the same magnitude.

This is why the crate doesn't initially move; the backward force from the crate cancels out the forward force you exert on it. However, once the crate breaks free and starts moving, the situation changes.

Now, as you continue to push the crate along the floor, the force you exert on the crate is greater than the force the crate exerts on you. This is because the crate has overcome static friction and is now experiencing kinetic friction, which is generally smaller in magnitude than static friction.

The force you exert on the crate needs to be greater than the force of kinetic friction to accelerate the crate and maintain its motion. So, in this case, the force exerted by you on the crate is greater than the force exerted by the crate on you.
