The distance travelled by the car along the plane is 29.56 m.

The acceleration of the car down the incline is calculated by applying Newton's second law of motion as shown below;

F - Ff = ma

where;

frictional force acting on the car, Ff = μmg cosθ

0 - μmg cosθ = ma

-μmg cosθ = ma

-μg cosθ = a

where;

a = -(0.45 x 9.8 x cos11)

a = -4.33 m/s²

The distance travelled by the car along the plane is calculated as follows;

v² = u² + 2aL

where;

0 = (16²) + 2(-4.33)L

0 = 256 - 8.66L

The statement as it has been written in the question is false. This is because, the upthrust must be equal to the weight in order for the object to float.

The principle of floatation states that an object would float in water when the upthrust on the object is equal to the weight of the object. We know that the upthrust is the force that acts on an object thereby throwing it up. The weight is the force that tries to sink the object into the fluid.

The location of the centre of the mass of the CO molecule relative to the carbon atom is 6.46 ×10⁻¹¹ m.

The Centre of Mass of that object is a position that is relative to an object or a system of objects. The average position of all parts of the system that are weighted to their masses is known as the Centre of Mass.

Given, the distance between the carbon and oxygen atoms, r = 1.13 ×10⁻¹⁰m.

The ratio of the mass of the carbon and oxygen:

Mc/Mo = 12/16 = 0.750

Consider that Xc is the position of carbon and Xo is the position of the oxygen atom in CO molecule.

The centre of the mass of the system is equal to the:

[tex]X_{co}=\frac{M_CX_C+M_OX_O}{M_C+M_O}[/tex]

[tex]X_{co}=\frac{(M_C/M_O)X_C+X_O}{M_C/M_O+1}[/tex]

As we are calculating the centre of the mass relative to the carbon atom.

Since he pilot releases the brakes and he finds that the plane still does not start to move, the  explanation I agree with is option C:

The lift of the airplane is provided by the flow of air around the wings. Additionally, the wings' form contributes to lift. The airplane is being pulled toward Earth by weight. The weight of an airplane is distributed evenly from front to back during construction.

Note that the design of an airplane wing is intended to speed up airflow across the top of the wing. Air pressure decreases when it moves more quickly. Therefore, the pressure at the top of the wing is lower than that at the bottom. The pressure differential exerts a force on the wing, lifting it into the air.

After being pushed away from the departure gate, an aircraft is standing still with the brakes applied and the engine running on very low. When the pilot releases the brakes he finds that the plane still does not start to move. Here are three explanations for why the plane does not move. Which one do you agree with?

A. When a single force that is too weak acts on an object it will not move. When the pilot releases the brakes the only force acting on the plane is that of the

engines but because this force is too weak, the plane will not move.

B. When the pilot releases the brakes two forces act on it. The engines exert a force in one direction and the ground exerts a force on the wheels in the opposite direction. The plane does not move because the force exerted by the ground on the wheels is stronger than the force of the engines.

C. When the pilot releases the brakes two forces act on it. The engines exert a force in one direction and the ground exerts a force on the wheels in the opposite direction. The plane does not move because the force exerted by the ground on the wheels is the same strength as the force of the engines.

g = 9.8 m / s²

μ[tex]_{k}[/tex] = 0.45

W = m g

W = 1090 * 9.8

W = 10682 N

Resolving W into its horizontal and vertical components,

[tex]W_{y}[/tex] = W cos θ

[tex]W_{y}[/tex] = 10682 * cos 11°

[tex]W_{y}[/tex] = 10682 * 0.98

[tex]W_{y}[/tex] = 10468.36 N

[tex]W_{x}[/tex] = W sin θ

[tex]W_{x}[/tex] = 10682 * sin 11°

[tex]W_{x}[/tex] = 10682 * 0.19

the colder air is more dense, then you would go through more mass (density) in a shorter vertical distance,

Explanation

Consider cold and warm air columns with equal weights, and equal amounts of overlying air.

Colder air is denser because the molecules of air are more closely packed together. As a result, pressure decreases more rapidly as you ascend through cold air than through warm air

It takes a shorter column of cold air to exert the same pressure as a taller column of warm air.

so,Since the colder air is more dense, then you would go through more mass (density) in a shorter vertical distance,

Energy can neither be created nor destroyed. It can only be transferred from one object to another.

Claim 2 is correct.

Energy cannot be created or destroyed. So, objects can not make their own energy.

Energy can be transferred or transformed. Energy can be changed in many ways, such as conversion of kinetic energy into potential energy and vice-versa, when one object moves another object, etc.

For example, to lift an object against the gravity, work is done on the object. This work is converted in the form of potential energy, called as gravitational potential energy. When an object, say an apple falls towards Earth from a tree, gravitational potential energy is converted into kinetic energy.

The minimum force that the contestant must exert to get the block moving is 53.33 N and the acceleration of the block is 0.874m/s² once it starts to move and the force is maintained.

When a force is applied at an angle, the force will have two components, one along the floor and one along the vertical.

If the force is F applied at an angle θ, then the vertical component of force is Fsinθ and the floor component is Fcosθ.

In out case θ = 25°,

A.) There will we a frictional force acting on the body which will be opposite to the component of the force which is along the floor, if the floor component just overcomes the static frictional force than the block will start to move.

So, we can write,

Friction force =  Fcosθ

μN = Fcosθ

where,

μ is the coefficient of static friction,

N is the normal reaction by the floor on the block which would be equal to the mg,

F is the minimum force Applied.

Putting all the values,

(0.1)(10)(48) = (F)(cos25°)

48 = F(0.9)

F = 53.33 Newtons.

B.) When the block will start moving,

There will be a kinetic frictional force on it as well as a Fcosθ on it,

The friction will be opposite direction of the motion, Fcosθ will be in the direction of the motion,

So, we can write, The net force on the body

F = Fcosθ - Fr

F = Fcosθ - μN

F = Fcosθ - umgsinθ

When the box is moving the normal reaction N will be equal to the vertical component of the force,

Here, u is the coefficient of kinetic friction,

Putting all the values,

F = 48 - 0.03x10x48x0.42

F = 48 - 6.048

F = 41.95 N

we can also write,

F = ma

where a is the acceleration of the block and m is the mass of the block,
