Referring to the graph below of data describing a cart pulled across a level surface. When a 4 N force pulls on the cart, the cart accelerates at 5 m/s^2. What is the friction force resisting the pull?

Answers

Answer:

0.5 N

Explanation:

(0.6 kg)(9.8 m/s^2) = 5.88 N

(0.6 kg)(5 m/s^2) = 3 N

4 N - 3 N = 1 N

1 N/5.88 N = 0.17

(0.17)(3 N) = 0.51 N which rounds to 0.5 N

When a 4 N force pulls on the cart, the cart accelerates at 5 m/s². The frictional force resisting the pull is 0.5 N.

What is friction?

Friction is defined as the force preventing sliding solid surfaces, fluid layers, and material components from moving relative to one another. When two bodies in contact move in relation to one another, friction, a resistive force, arises. friction factors Between-body surface adhesion: When two materials are in close proximity to one another, a molecular force called adhesion is created.

(0.6 kg) (9.8 m/s²2) = 5.88 N

(0.6 kg) (5 m/s²2) = 3 N

4 N - 3 N = 1 N

1 N/5.88 N = 0.17

(0.17) (3 N) = 0.51 N ≅ 0.5 N

Thus, when a 4 N force pulls on the cart, the cart accelerates at 5 m/s². The frictional force resisting the pull is 0.5 N.

A light ray transfers from more to less dense medium at certain condition , if we repeat this experiment by increasing the angle of incidence in more dense medium to double its value in the 1st condition so the value of the relative refractive index between the 2 media is

increased to double
decreased to half
still constant
there is no relative refractive index between more and less dense medium

Answers

Answer:

The correct option is;

Still constant

Explanation:

The relative refractive index ₁n₂ between the two medium can be as follows;

[tex]_1n_2 = \dfrac{The \ speed \ of \ light \ in \ medium \ 1}{The \ speed \ of \ light \ in \ medium \ 2} = \dfrac{c_1}{c_2}[/tex]

Therefore, given that the speed of light in medium 1 is constant and the speed of light on medium 2 is also constant, the relative refractive index ₁n₂ = c₁/c₂ is always constant.

1. How much heat is produced if you heat .25 kg water from 25 degrees C to 100 degrees C. The specific heat of water is 4180 J/kg C.

Answers

Answer:

Q = 78375 [J]

Explanation:

To solve this problem we must use the following ideal equation for the thermal energy of an element or substance depending on the temperature change.

[tex]Q=m*C_{p}*(T_{final}-T_{initial})[/tex]

where:

Q = heat [J]

m = mass = 0.25 [kg]

Cp = specific heat = 4180 [J/kg*C]

Tinitial = 25[°C]

Tfinal = 100 [°C]

[tex]Q =0.25*4180*(100-25)\\Q = 78375 [J][/tex]

Explanation:

Un carro parte del reposo y acelera uniformemente a 4.0 m / s^2 durante 5.0 s. A continuación, mantiene la velocidad que alcanzó durante 10 s. Luego, disminuye la velocidad a una velocidad constante de 2.0 m / s^2 durante 4.0 s.

Answers

Answer:

Average speed of the car = 16.53 m.s

Explanation:

For first 5 seconds:

As the car starts from rest, so the initial speed of the car, u=0

Acceleration, a= 4 m/s^2

So, the final speed (speed at time, t=5 second)

v=u+at

v=0 + 4 x 5 = 20 m/s

Distance covered,

[tex]s=ut+\frac 1 2 a t^2 \\\\s=0+\frac 1 2 \times 4 \times 5^2[/tex]

s=50 m

As the car maintained the constant speed of 20 m/s for the next 10 seconds.

Distance traveled in 10 seconds, d=20 x 10 =200 m

For the last 4 seconds:

The car slows down at the rate of 2.0 m / s ^ 2 from the speed of 20 m/s.

As the car slows down, so the acceleration will be negative, i.e a=-2 m/s^2

[tex]s=ut+\frac 12 at^2 \\\\s=20\times 4 +\frac 12 (-2)4^2[/tex]

s=80-16=64 m.

Considering all three cases, the total distance covered=

=50+200+64=314 m

Total time= 5+10+4=19 s

So, the averate peed= Totat distance covered / total time taken

=314/19=16.53 m/s

Determine the molar mass of CeAl12O19.

Answers

Answer:

1 mole = 767.882 g

1 gram = 0.001 mole

Explanation:

The molar mass of CeAl₁₂O₁₉ is 770.686grams. The molar mass of a substance is the amount of substance which is present in one mole of the compound.

What is Molar mass?

Molar mass of a substance is the mass in grams of one mole of the compound or chemical substance. In a chemical substance, the amount of entities which are present such as atoms, molecules, ions, is defined as a mole. A mole of any substance has 6.022 × 1023 molecules in it.

The molar mass of CeAl₁₂O₁₉  can be calculated as it is made up of three atoms which are Ce (Cerium), twelve atoms of Aluminium (Al), and nineteen atoms of O (Oxygen).

Atomic mass of Cerium = 140.116u

Atomic mass of Aluminium = 26.981539 u

The mass of 12 Aluminium atoms = 12 × 26.98 u

The mass of 12 Aluminium atoms = 323.76 u

Atomic mass of Oxygen =  15.999 u

The mass of 19 atoms of Oxygen = 303.81 u

Therefore, the mass of CeAl₁₂O₁₉ = 140.116 u + 323.76 u + 303.81 u

The molar mass of CeAl₁₂O₁₉ is 770.686 grams.

The diagram is a real world example of the first and second laws of thermodynamics. It shows how thermal energy is used to generate electricity. Which best describes how the diagram illustrates both laws of thermodynamics?

Answers

Answer:

First law: kinetic energy is used to turn an electric generator

Second law: some thermal energy is lost to the environment as it travels through the system

Explanation:

The first law of thermodynamics is known as the law of conservation of energy. It states that energy can neither be created nor destroyed but can only be transferred or changed from one form to another. When thermal energy is used to generate electricity, the kinetic energy of the steam is used to turn the electric generator (thereby producing electrical energy).

The second law of thermodynamics states that energy transfer or transformation leads to an increase in entropy resulting in the loss of energy. This law also states that as energy is transferred or transformed, some is lost in a form that is unusable. When thermal energy is used to generate electricity, some of the thermal energy is lost to the environment as it travels through the system.

Assuming a constant force, and hence a constant acceleration a, we have by Newton's second law,

4.0 N = (1.2 kg) a   →   a = (4.0 N) / (1.2 kg)

and by definition of average velocity,

a = (5.0 m/s - 2.0 m/s) / t

where t denotes the time for which the force is applied.

So,

(4.0 N) / (1.2 kg) = (3.0 m/s) / t   →   t = (3.0 m/s) (1.2 kg) / (4.0 N) = 0.90 s

[tex]Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W][/tex]

Answer: Electromagnetic waves can transfer energy through empty space.

Explanation:

Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. The electric field and magnetic field of an electromagnetic wave are perpendicular to each other. They are also perpendicular to the direction of the wave.

Electromagnetic waves travel with speed of light in vacuum.

Electromagnetic wave does not need a medium to propagate or travel from one place to another. Electromagnetic waves are 'transverse' waves which means that they are measured by their amplitude and wavelength.

Electromagnetic waves do not lose energy when they travel and thus can travel far from its source.
