If you have the other values, use the momentum equation p = m•v to determine an object's momentum or velocity.

When the momentum of each automobile is known, the after-collision velocity may be calculated by dividing the momentum by the mass (v=p/m). We can predict some things about the relative velocities before and after the impact if kinetic energy and momentum are conserved. Both before and after the impact, the relative velocity's magnitude is the same.

The impact velocity is calculated using the formula below. Take the square root of the result to determine the impact velocity by multiplying the height by the acceleration caused by gravity twice.

A high-pressure system at the surface is created with sinking air.

High-pressure weather systems are also referred to as anticyclones that have higher atmospheric pressure at their center than the areas around them, resulting in cold air to be sinking. As the cold air sinks, it warms. It means that air can hold more water, so as a result no clouds or rain are formed.

So high-pressure weather system is associated with sinking air; on the other hand, a low-pressure weather system is associated with rising air.

Torque is a force that can cause an object to rotate around an axis. In the same way that force causes an object to accelerate in linear kinematics, torque causes an object to acquire angular acceleration. Torque is measured as a vector quantity. Torque is a rotational or twisting force expressed as a force. Vehicle engines generate torque by rotating about an axis. It can be thought of as a vehicle's strength.

Answer :Total pressure = 7293.2 torr or 9.60 atm

What is volume ?

-- Volume is a measure of three-dimensional space.

--  It is often quantified numerically using SI derived units or by various imperial or US customary units.

-- The definition of length is interrelated with volume.

Total pressure = partial pressure of nitrogen + partial pressure of oxygen

The partial pressure due to nitrogen is determined using the equation of Gay-Lussac's law: P₁/T₁=P₂/T₂

P₁ = 760 torr = 1atm, T₁ = 28∘C = (273+28)K = 301k, P₂ = ?, T₂ = 310∘C =(310+273)K = 583K

P₂ = P₁ T₂/ T₁

P₂ = 760 * 583 / 301 = 1472.03 torr

The pressure due to Oxygen gas produced is calculated thus:

Balanced equation of the decomposition of Ag₂O at s.t.p. is as follows;

2Ag₂O ----> 4Ag + O₂(g)

2 moles of Ag₂O produces 1 mole of O₂

molar mass of Ag₂O = (2*108 + 16)g = 232g/mol

molar volume of gas at s.t.p. = 22.4L

2*232g i.e. 464g of Ag₂O produces 22.4L of O₂

5.57g of Ag₂O will produce 5.57g*22.4L/464g = 0.269L or 269mL of O₂

Using the General gas equation  P₁V₁/T₁=P₂V₂/T₂

P₁ = 1atm = 760 torr, V₁ = 269mL, T₁=273K, P₂ = ?, V₂= 75mL, T₂ = 583K

P₂ = P₁V₁T₂/V₂T₁

P₂ = 760*269*583 / 75*273

P₂ = 5821.17 torr

Answer:

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be different due to factors such as air resistance and efficiency of the crane.

Explanation:

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. To determine the height to which the car was lifted, we need to use the equation of work done (W) which is equal to the force applied (F) multiplied by the distance moved (d). Work done here is equal to 3MJ, force applied is equal to the mass of the car (10,000 kg) multiplied by the gravitational acceleration (10m/s2). Therefore, the equation to determine the distance moved (d) is:

W = Fd

3MJ = (10,000kg)(10m/s2)d

d = 3MJ/(10,000kg)(10m/s2)

d = 3,000m

This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be slightly different due to various factors such as air resistance and the efficiency of the crane.

To understand how this calculation was made, it is important to understand the concept of work. Work is defined as the product of force and the distance moved in the direction of the force. In this case, the force is the gravitational force acting on the car which is equal to the mass of the car multiplied by the gravitational acceleration (10m/s2). The distance moved is in the direction of the gravitational force which is upwards.

The next step is to calculate the work done by the crane in lifting the car. Work done is equal to the force applied multiplied by the distance moved. Here, the force applied is the mass of the car (10,000 kg) multiplied by gravitational acceleration (10m/s2) and the distance moved is the height to which the car was lifted. From the equation of work done, we can calculate the distance moved (d) which is equal to the work done (3MJ) divided by the force applied (10,000kg)(10m/s2). This gives us a value of 3,000m for the distance moved, which is the height to which the car was lifted.

In conclusion, the amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be slightly different due to various factors such as air resistance and the efficiency of the crane.

The height of the car is lifted is 3,000m.

Work done by a force is defined as the product of the displacement and the component of the applied force on the object in the direction of displacement. When we push a block with some force, the body moves with some acceleration, work is done.

Work done can be calculated with this equation:

Work = Force x Distance.

The SI unit for work is the Newton meter (N m).

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. To determine the height to which the car was raised, we need to use the equation for work done (W), which is equal to the force applied (F) multiplied by the distance moved (d). Here the work done is equal to 3MJ, the force applied is equal to the mass of the car (10,000 kg) multiplied by the acceleration due to gravity is [tex]10m/s^2[/tex]

W = Fd

3MJ = (10,000)(10)d

d = 3/(10,000)(10)

d = 3,000m
