When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater collision force. When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater momentum change.

Explanation:

The weight of a \(45 kg\) box is \(441.45 N\).

Weight refers to the measure of the force exerted on an object due to the gravitational pull of the Earth.

Given the mass of the box is \(m=45 kg\).

The weight of an object (\(W\)) can be found by multiplying the mass of the object (\(m\)) by the acceleration due to gravity (\(g\)).

So, \(W=mg\).

It is known that acceleration due to gravity, \(g=9.81 m/s^2\).

Hence, the weight of the box, \(W=(45kg)\times (9.81 m/s^2)\).

\(\Rightarrow W=441.45 (kg\cdot m/s^2)\\\Rightarrow W=441.45 N\)

Therefore, the weight of the box is \(441.45 N\).

The increase in internal energy of the tie and spike is approximately 1.12 Joules.

The initial kinetic energy of the spike is:

K_i = (1/2) * m * v^2

K_i = (1/2) * 0.60 kg * (1.8 m/s)^2

K_i = 1.94 J

The amount of kinetic energy that is absorbed as internal energy is:

K_absorbed = 0.578 * K_i

K_absorbed = 0.578 * 1.94 J

K_absorbed = 1.12 J

Thus,the value is 1.12 Joules.

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.

Planes primarily operate in the troposphere because this is the layer of the atmosphere that is closest to the Earth's surface and it's where most of our weather occurs. The troposphere extends from the Earth's surface up to about 7-20 km (5-12 miles) and it contains about 80% of the total mass of the atmosphere. The air is also denser in this layer, making it easier for planes to generate lift and fly efficiently. Additionally, the troposphere is where the majority of commercial and civilian air traffic occurs, as it is the layer that is best suited for takeoff, landing and cruising of planes. Planes are able to fly in higher layers of the atmosphere, but the conditions become more challenging and it's less common for commercial planes to operate in those layers because it would require specialized equipment and training.

The resultant array is v = [10; 13; 82; 91; 92; 64].

To perform an insertion sort, we start with the first element of the array and iterate through the remaining elements. For each element, we compare it with the elements before it and insert it in the correct position.

Given the array v = [82; 91; 13; 92; 64; 10], let's perform two full insert processes:

1. First insert process:
- v = [82; 91; 13; 92; 64; 10]
- Compare 91 with 82. Since 91 is greater, no change is needed.
- Compare 13 with 91 and 82. Move 13 to the beginning of the array.
- v = [13; 82; 91; 92; 64; 10]

2. Second insert process:
- v = [13; 82; 91; 92; 64; 10]
- Compare 82 with 13. Since 82 is greater, no change is needed.
- Compare 91 with 82 and 13. Since 91 is greater, no change is needed.
- Compare 92 with 91, 82, and 13. Move 92 to the end of the array.

Explanation:

According to the question the heat capacity of the object is approximately 11.92 J/K.

The heat capacity of an object is defined as the amount of heat energy required to raise the temperature of the object by 1 degree Celsius (or 1 Kelvin).

In this case, the temperature of the object increases by 41.4 °C when it absorbs 3749 J of heat. Therefore, we can calculate the heat capacity using the formula:

Heat Capacity = Heat Energy / Temperature Change

Heat Capacity = 3749 J / 41.4 °C

To ensure consistent units, we need to convert the temperature change from Celsius to Kelvin:

Temperature Change in Kelvin = 41.4 °C + 273.15 K = 314.55 K

Heat Capacity = 3749 J / 314.55 K

Heat Capacity ≈ 11.92 J/K

Therefore, the heat capacity of the object is approximately 11.92 J/K.

The magnitude of the force per unit length is, \(F = \dfrac{\mu_0 \times i^2}{2 \times \pi \times d}\). The force is attractive when the currents flow in the same direction in both wires, and repulsive when they flow in opposite directions.

The magnitude of the force per unit length (also known as the force per unit of current) that each wire exerts on the other can be calculated using the formula:

\(F = \dfrac{\mu_0 \times i_1 \times i_2}{2 \times \pi \times d}\)

where \(\mu_0\) is the magnetic constant (also known as the permeability of free space) and has a value of \(4\pi \times 10^{-7}\) Tm/A, i₁ and i₂ are the currents in the wires, and d is the distance between the wires.

The current is same in both the wires that is i. Hence, the force per unit length will be,

\(F = \dfrac{\mu_0 \times i \times i}{2 \times \pi \times d}\\\\F = \dfrac{\mu_0 \times i^2}{2 \times \pi \times d}\)

The force is attractive when the currents flow in the same direction in both wires, and repulsive when they flow in opposite directions. This is because the magnetic fields produced by the current-carrying wires interact with each other, and the direction of the resulting force depends on the relative orientation of the magnetic fields.

If the currents are in the same direction, the magnetic fields reinforce each other, resulting in an attractive force. If the currents are in opposite directions, the magnetic fields oppose each other, resulting in a repulsive force.

B) The evidence that a chemical reaction has likely occurred is the formation of a precipitate.

A precipitate is a solid that forms from a chemical  response in a liquid  result. This is a clear  suggestion that a chemical  response has taken place because the reactants have  experienced a chemical change to form a new product that's  undoable in the original detergent.   Option A( a liquid  sluggishly losing volume) may be an  suggestion of evaporation or  immersion, but it doesn't  inescapably indicate a chemical  response.

Option C( boiling water releasing) is a physical change caused by a change in temperature, not a chemical  response.

9 ma at 1.9 v for 382 h (under other test conditions, the battery may have other ratings).The battery stores approximately 0.0066366 kJ of total energy.

The total energy stored in the battery can be calculated by multiplying the current (I) by the voltage (V) and the time (t) for which the battery is used. In this case, the current is 9 mA (0.009 A), the voltage is 1.9 V, and the time is 382 hours.
To calculate the total energy (E), we can use the formula:
E = I * V * t
First, we need to convert the current from milliamperes to amperes:
Current = 9 mA = 0.009 A
Now we can calculate the total energy:
E = 0.009 A * 1.9 V * 382 hours
To convert the energy from joules (J) to kilojoules (kJ), we divide the result by 1000:
E = (0.009 A * 1.9 V * 382 hours) / 1000
Simplifying the equation, we get:
E = 0.0066366 kJ
Therefore, the total energy stored in the battery is approximately 0.0066366 kJ, rounded to two decimal places.
In conclusion, the battery stores approximately 0.0066366 kJ of total energy.

To calculate the angle of refraction when a ray travels from one medium to another, you can use Snell's law, which states:

n₁ * sin(θ₁) = n₂ * sin(θ₂), where:

n₁ = refractive index of the first medium

θ₁ = angle of incidence

n₂ = refractive index of the second medium

θ₂ = angle of refraction

In this case, the ray is traveling from Quartz (n₁ = 1.46) to Water (n₂= 1.33), and the angle of incidence is 35.0 degrees.

Plugging the values into Snell's law, we have:

1.46 * sin(35.0°) = 1.33 * sin(θ₂)

Rearranging the equation to solve for θ₂:

sin(θ₂) =\(\frac{1.46 * sin(35.0^{0})}{1.33}\)

θ₂ = arc sin(\frac{1.46 * sin(35.0^{0})}{1.33})

Using a calculator, we can evaluate this expression:

θ₂≈ arc sin(0.8948) ≈ 61.64°

Therefore, the angle of refraction in water (n = 1.33) is approximately 61.64 degrees.

The magnitude of the impulse that the plate gives to the bullet is 6.7 N

We know change in momentum horizontally = m v cos Ф2 - m u cos Ф1

and change in momentum vertically = m v sinФ2 - (- m u sinФ1)

where, m = mass = 20g = 0.02 kg

v = final velocity = 320 m/s

u = initial velocity = 350 m/s

Ф1,Ф2 = angle = 30 degrees

Putting these values we get,

Change in momentum horizontally = - 0.5196 kg-m/s

Change in momentum vertically = 6.700 kg-m/s

Magnitude of change in momentum is : \(\sqrt{-0.5196^{2} + 6.7^{2} } = 6.7 N\)
