Answer:

P₄ + 3O₂ → 2P₂O₃

Explanation:

To balance an equation we take each element one by one on each side and balance their atoms.

Like P₄ (Tetraphosphorus) in the left side has 4 atoms of phosphorus.

While on the right side P₂O₃ (Diphosphorus Trioxide) has 2 Phosphorus atoms.

So place 2 as a coefficient in front of P₂O₃.

Now Phosphorus atoms (4 atoms) are balanced on each side.

Now number of Oxygen atoms in P₂O₃ = 2 × 3 = 6

On the left left side number of Oxygen atoms in O₂ = 2

To balance Oxygen atoms in each side, place 3 as a coefficient before O₂ on the left.

Therefore, balance equation will be,

P₄ + 3O₂ → 2P₂O₃

A rocket ship has several engines and thrusters. While the solid rocket booster (srb) and main engines only work together during the first 2 minutes of flight, the main engines operate for a total of 8. 5 minutes after the launch. Once the srbs are released, the main engines alone accelerate the rocket from about 1341 m/s to 7600 m/s. During the first two minutes of flight, the SRB and main engine accelerate at a rate of 52.16 m/s2.

Acceleration is the rate at which a moving object's speed and direction change over time. When something moves faster or slower, it is considered to be accelerating. The engine's initial velocity (u), final velocity (v), and time of motion (t), which is equivalent to two minutes, are the parameters given (2 x 60 s).

The calculations for the main engine's and SRB's acceleration are listed below.

a= Δv / Δt

a=7600-1341 /2*60s

a=52.16 m/s²

As a result, during the first two minutes of flight, the main engine and SRB accelerate at a rate of 52.16 m/s2.

Answer:

B. Kinetic energy of the system is partially used up in the deformation of the vehicles.

Explanation:

In an inelastic collision, momentum is conserved, but kinetic energy is not. Kinetic energy is lost as heat or lost in the deformation of the objects.

The correct statement about Kinetic energy of the system after the collision is that KE of the system will be partially used up in the deformation of the vehicles. Hence, option B is correct.

The force that an object has because it is moving is known as kinetic energy in physics. It is defined as the quantity of effort required to accelerate anybody of a specific mass from rest to its specified velocity. The body keeps its kinetic energy after acquiring it during acceleration, barring changes in speed.

When slowing from its current pace to a condition of rest, the body expends the very same amount of energy. Any term in the Lagrangian of a system that has a derivative in regard to time is formally referred to as kinetic energy.

The momentum of an object is conserved, but kinetic energy is not in an inelastic collision. In the form of heat or by the distortion of the objects, kinetic energy is lost.

Explanation:

If a light bulb uses 60J of electrical energy and produces 30 J of light energy, the percent efficiency of the light bulb is 50%.

The total amount of beneficial work accomplished, excluding waste and spoilage, is known as output or work output.

This pulp creates 30 jewels' worth of light energy, for a total of 60 jewels. So that's the energy output. Let's use E. O. to symbolize it. Those are 30 Jews.

Additionally, we must calculate the light bulb's efficiency %. Therefore, we will start by computing the efficiency, which is defined as the ratio of energy output to energy input in this book.

And 30/60 is the efficiency that we obtain. Moreover, this is 1 x 2.

The straightforward ratio between output and input energy—by 100. And the result is that this is 50%. That is the required efficiency percentage for this light bulb.

The ratio of the number of turns in the primary and the secondary coil of a step-up transformer is 1 : 200.

The formula for calculating the secondary voltage in a transformer is: N = V = Where No and N are the primary and secondary coils' respective turn counts; V and V are the RMS voltages across the primary and secondary coils, and I and Is are the primary and secondary currents.

Calculation: Due to this:

The coil's N2 to Ns turn ratio is 1/20.

We understand that N=1/20 = 4/LP: Is = 20:1.

The transformer uses the following principles: A wire's magnetic field moves as a result of a changing current flowing through it. A wire exposed to a moving magnetic field will create a changing current.One of the coils produces a magnetic field that grows and contracts in response to the changing voltage of the AC when an AC source is connected to it.

In other words, the coil generates a growing magnetic field as the voltage across it rises. The magnetic field generated around the capacitor increases when the voltage reaches its maximum and starts to decline.

velocity of the two sound waves, v = 343 m/s

wavelength of the first wave, λ₁ = 5.72 m

wavelength of the second wave, λ₂ = 11.44 m

The frequency of the first wave is calculated as follows;

F₁ = v/λ₁

F₁ = 343 / 5.72

F₁ = 59.97 HZ

The frequency of the second wave is calculated as follows;

F₂ = v/λ₂

F₂ = 343 / 11.44

F₂ = 29.98 Hz

The beat frequency is calculated as;

Fb = F₁ - F₂

Fb =  59.97 HZ - 29.98 Hz

A refracting and reflecting telescope have the same diameter; the refracting telescope will be much longer than the reflector'

The answer choice is true.

Because refracting and reflecting telescopes are designed differently, they can have different lengths even though they have the same diameter. Refracting telescopes, commonly known as refractors, bend and concentrate light to create images. The length of a refractor is mostly dictated by the size of its objective lens, which is the primary light-gathering lens at the front of the telescope. A bigger lens necessitates a longer tube in order to accommodate it, resulting in a greater overall length of the telescope.

Reflecting telescopes, also known as reflectors, on the other hand, employ mirrors to gather and focus light. The length of a reflector telescope is dictated by the size of its primary mirror. A longer optical tube is required to accommodate a larger mirror, but it does not have to be as long as a refractor of the same diameter because the light from the mirror travels a shorter distance before reaching the eyepiece.

Even if a refractor and a reflector have the same diameter, the refractor will be considerably longer due to the length necessary to accommodate its huge lens, but the reflector will have a lower overall length since the light it gathers travels a shorter journey.

The strong nuclear force overcomes the repulsive electric force of protons in the atomic nucleus because it is a much stronger force. It is able to act over very short distances and is mediated by particles that are much heavier than electrons and photons.

The repulsive electric force of protons in the atomic nucleus does not cause the protons to fly apart because of the strong nuclear force. The strong nuclear force is an attractive force between nucleons that overcomes the repulsion between protons due to the electromagnetic force. This force is responsible for holding the nucleus of an atom together.

We will explain the physics behind why the strong nuclear force overcomes the repulsive electric force. The protons in the nucleus are positively charged and would normally repel each other due to the electrostatic force. The reason why they do not is because they are held together by a stronger force, the strong nuclear force. This force acts between nucleons, which are particles found in the nucleus of an atom. The strong nuclear force is a short-range force that acts over distances of less than a femtometer. It is much stronger than the electrostatic force, which is why it is able to hold the nucleus together. The reason for this is that the strong nuclear force is mediated by particles called mesons, which are much heavier than electrons and photons. The strong force is able to overcome the repulsion between protons because it is much stronger than the electromagnetic force, which is what causes the repulsion in the first place.

No matter where an object is in the universe, the more matter an object has, the more mass it will have as well.

Answer:

The time it will take the bomb to reach the target is approximately 2.402 seconds

Explanation:

The given information are;

The direction the bomber is travelling = 45° below the horizontal

The speed at which the bomber was travelling = 320 m/s

The elevation at which the bomber releases its load = 600 m

Therefore, we have;

The height at which the bomb is released, s = 600 m

The inclination of the direction of motion of the bomb = 45° below the horizontal

The magnitude of the velocity of the bomb at release = 320 m/s

The vertical component of the velocity = 320 m/s × sin(45°) = 160·√2 m/s

Therefore, the initial vertical velocity, \(u_v\), of the bomb = 160·√2 m/s downwards

From the equation of motion, we have;

s = \(u_v\) × t + 1/2 × g × t²

Where;

t = The time it takes the bomb to hit the target

g = The acceleration due to gravity = 9.81 m/s²

∴ 600 = 160·√2 × t + 9.81 × t²

9.81 × t² + 160·√2 × t - 600 = 0

By the quadratic formula, we have;

\(x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}\)

\(t = \dfrac{-160 \times \sqrt{2} \pm \sqrt{(160 \times \sqrt{2} )^{2}-4\times 9.81\times (-600)}}{2\times 9.81}\)

t ≈ -25.467 seconds or t ≈ 2.402 seconds

Given that t is a natural number, we have the correct option is t ≈ 2.402 seconds

Therefore, the time it will take the bomb to reach the target ≈ 2.402 seconds.

Answer:  the hunter should aim his rifle 3,422 meters above the deer to hit it.

Explanation: We can solve this problem using projectile motion equations. Let's first identify the known variables:

Distance to the deer along the line of sight (horizontal distance): d = 10,181 m

Height of the hill: h = 90 m

Muzzle velocity of the gun: v0 = 100 m/s

Acceleration due to gravity: g = 10 m/s^2

We want to find the vertical distance (height) between the hunter's location and the deer, which we can call y. We can use the following equation for the vertical motion of a projectile:

y = v0tsin(theta) - (1/2)gt^2

where t is the time it takes for the bullet to reach the deer, and theta is the angle between the line of sight and the horizontal (the angle at which the rifle is aimed).

To find t, we can use the fact that the time of flight of a projectile is given by:

T = 2v0sin(theta)/g

We can solve for sine(theta) using the fact that the horizontal distance is related to the time of flight by:

d = v0*cos(theta)*T

Combining these equations, we get:

sin(theta) = d/(2Tv0)

cos(theta) = sqrt(1 - sin^2(theta))

t = T/2

Substituting these values back into the equation for y, we get:

y = (d*t/tan(theta)) - (1/2)gt^2

Now we just need to plug in the numbers and solve for y:

sin(theta) = 90/10,181

theta = arcsin(sin(theta)) = 0.523 degrees

cos(theta) = cos(0.523) = 0.999

T = 2100sin(theta)/g = 3.189 seconds

t = T/2 = 1.595 seconds

y = (10,181*t/tan(theta)) - (1/2)gt^2 = 3,422 meters

Therefore, the hunter should aim his rifle 3,422 meters above the deer to hit it. Note that this assumes no air resistance and that the rifle is perfectly aimed. In reality, the bullet would be affected by air resistance and the trajectory would depend on the accuracy of the rifle and the shooter's skill.

The magnitude of momentum of the ball after 3.333 sec is 10F/3 kg.m/sec. None of the options provided match this answer exactly.

What is Momentum?

Momentum is a physical property of an object that describes its motion. It is defined as the product of an object's mass and velocity, and it is a vector quantity, which means it has both magnitude and direction.

The magnitude of momentum of the ball after 3.333 sec can be calculated using the equation:

p = m * v

where p is momentum, m is mass, and v is velocity.

Given that the ball gains a velocity of 6m/s from the force and stops after 10 seconds, we can calculate the mass of the ball as:

v = F * t / m

6 = F * 10 / m

m = 10F / 6

m = 5F / 3

Now, we can calculate the momentum of the ball after 3.333 sec using the above equation:

p = m * v

p = (5F / 3) * (6 * 3.333 / 10)

p = (5F / 3) * 2
