Answers

Answer: For forces on flat rigid bodies such as a wall, it is less direct in the calculation of work done as force times distance or displacement compared to other situations. You will have to calculate the pressure exerted first which will be P = F/A, where F is the force as above in Newtons, and A is the area of the wall first. There should also be a pressure limit for the wall in question based on what it is composed of and its dimensions from structural mechanics. The exerted force must exceed the upper limit of tolerated force to break the wall. In any case even without breaking the wall, using very accurate optical technology you can estimate the displacement now a days however minute, or the change in the form of volume of displacement also due to the pressure. Here Work done can be given still as follows : W = F •d, or W = P •V, or W = (F/A)•V. Here V will be the approximate

What do you mean by kinetic energy ?

The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:

Kinetic energy = 1/2 mv²

Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.

Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.

Thus, option 4 is correct.

PLEASE. A 20 kg box is being pulled across a floor by a horizontal rope. The tension in the rope is 99 Newtons. The coefficient of friction is 0.25. What is the force of friction on the box? What is the acceleration of the box?

Answers

Answer:

Force of Friction = -50 (N)

Acceleration = 2.45 (m/s^2)

Explanation:

Force of Friction = f = N * coefficient of friction

N = m * g

=> Force of Friction = m * g * coefficient of friction

f = 20 * 10 * -0.25 = -50 (N)

------------------------------------------------------

(1) F net = F + f

(2) F = m * a

(1) F net = 99 - 50 = 49

(2) a = 49 / 20 = 2.45 (m/s^2)

John is pushing (horizontally) on a 100 kg bench with a force of 380 Newtons. What is the size of the friction force acting on the bench if the coefficient of static friction is 0.4? Where will the bench be 10 seconds after John starts pushing

Answers

Answer:

dx = 0

Explanation:

The Force of Friction = N * coefficient of static friction

N = m * g

=> The Force of Friction = m * g * coefficient of static friction

The Force of Friction = 100 * 10 * 0.4 = 400 (N)

The Force of Friction > The Force of John

=> It won't move!

The bench will not move because the friction force is more than john's applied force. Friction force= 392 N

Calculation

[tex]f_{k} =[/tex][tex]u_{k} *F_{N}[/tex]

where,

[tex]f_{k}[/tex] is friction force,

[tex]u_{k}[/tex] is coefficient of friction.

[tex]F_{N}[/tex] is the normal force

⇒[tex]f_{k} =0.4(100*9.8)=392 N[/tex].

Hence Force applied by john, 380N is less than the Frictional force, 392N.

What is friction?The resistance to motion of one object moving in relation to another is known as friction.It is not regarded as a fundamental force like gravity or electromagnetic.The interplay of small bumps on the surfaces of objects as they rub together is thought to be the primary source of friction, though scientists are not entirely certain of this.Particles that stick out above the rest can be found on even the most smooth surfaces.As the objects move, these high points collide and scrape against one another, creating resistance.Friction is brought on by this unwillingness to move.Sliding friction, fluid friction, and rolling friction are the three primary categories into which friction can be categorized. The items that are moving and the force being applied to them determine the type of friction.

What is kinetic energy?

Kinetic energy of a substance is the energy generated by virtue of its motion. It is dependent on the mass and velocity of the substance. Temperature of the system also affects the kinetic energy of substance.

According to kinetic theory of matter, as thermal energy increases, kinetic energy of the particles also increases leading to more effective collisions results in reactions.

Here, the color spreads more easily in sample 2 because the higher temperature of the solution provide enough thermal energy for the liquid particles to gain kinetic energy to easily move through the solution. Thus, statement d is correct.
