Explanation:

Answer:

Cellulose

Explanation:

Cellulose is the carbohydrate which is unable to be digested by body. Adding fiber's (cellulose)  to one's diet reduces blood cholesterol level because soluble fiber  dissolves in water to form a gel, which moves slowly through the intestines binding up fat, dietary cholesterol, bile salts, and sugar to be excreted. Once excreted, these are no longer available to build more cholesterol. Also cellulose remains undigested but is effectively making one gain more calories, so it helps prevents over eating.

Screw pump, Drill Machine, Bottle Caps, Faucets and Car Jack are the five examples of screws that we see in everyday life.

Screw is defined as a short, sharp-pointed metal pin with a raised helical thread present round it. It has a slotted head that is used to join things together by rotating it so that it pierces wood and is held tightly on its place. Screw is used in many materials in order to join two frames or bodies with each other. Without this screw, we can't imagine many materials to work together so screw has very high importance.

So we can conclude that Screw pump, Drill Machine, Bottle Caps, Faucets and Car Jack are the five examples of screws that we see in everyday life.

Answer:

F = 780 [N]

Explanation:

To solve this problem we must use newton's second law which tells us that the sum of forces on a body must be equal to the product of mass by acceleration

ΣF =m*a

where:

F = force [N] (units of Newtons)

m = mass = 2600 [kg]

a = acceleration = 0.3 [m/s²]

F = 2600*0.3

F = 780 [N]

Answer:

The length of rod A will be greater than the length of rod B

Explanation:

We, know that the formula for final length in linear thermal expansion of a rod is:

L' = L(1 + ∝ΔT)

where,

L' = Final Length

L = Initial Length

∝ = Co-efficient of linear expansion

ΔT = Change in temperature

Since, the rods here have same original length and the temperature difference is same as well. Therefore, the final length will only depend upon the coefficient of linear expansion.

For Rod A:

∝₁ = 12 x 10⁻⁶ °C⁻¹

For Rod B:

∝₂ = β₂/3

where,

β₂ = Coefficient of volumetric expansion for rod B = 24 x 10⁻⁶ °C⁻¹

Therefore,

∝₂ = 24 x 10⁻⁶ °C⁻¹/3

∝₂ = 8 x 10⁻⁶ °C⁻¹

Since,

∝₁ > ∝₂

Therefore,

L₁ > L₂

So, the length of rod A will be greater than the length of rod B

Answer:

The correct option is D

Explanation:

When an object at rest is acted upon by an external force, the motion gained (of the body) will proceed in the direction of the force. This is caused by the workdone by the bat on the ball. The motion gained mentioned earlier is the kinetic energy.

Kinetic energy can be described as the energy in a moving object.

Answer:

(D) work done by the bat on the ball

Explanation:

The principle of work-energy theorem, states that work done by the sum of all the forces acting on an object, is equal to the gain in the kinetic energy of the object.

When the baseball bat strikes the baseball which causes a displacement in the initial position of the baseball, work is said to be done which is equal to the change in the kinetic energy of the baseball.

Thus, The kinetic energy gained by the baseball as it leaves the bat is due to the work done by the bat on the ball.

Answer:

a) Approximately 0.2066 m

b) 0.00002568443 s

c) Approximately 188.87 s

Explanation:

a) The total energy of the electron = 190GeV

The rest energy of the electron = 0.51 MeV

[tex]\dfrac{19 \ GeV}{0.51 \ MeV} = 37254.902 = \dfrac{1}{\sqrt{1 + \dfrac{u^2}{c^2} } }[/tex]

[tex]\left ( 1 - \dfrac{u^2}{c^2} \right ) = \dfrac{1}{37254.902^2} } }[/tex]

[tex]\left ( 1 - \dfrac{1}{37254.902^2} } } \right ) = \dfrac{u^2}{c^2}[/tex]

u = √(299792458² × (1 - 1/37254.902²)) = 299792457.892

β = v/c = 299792457.892/299792458 = 0.99999999964

[tex]\beta = \sqrt{1 - \left ( \dfrac{\Delta x}{\Delta x'} \right )^2}[/tex]

Δx = √(Δx'²×(1 - β²)) = √(7700²×(1 - 0.99999999964²)) ≈ 0.2066 m

The length of the tube in the electron's frame ≈ 0.2066 m

b) The time in the frame of the electron is given as follows;

Δt' = 7700/299792457.892 = 0.00002568443 s

c) The time in the frame of the tube is given as follows;

[tex]\beta = \sqrt{1 - \left ( \dfrac{\Delta t'}{\Delta t} \right )^2}[/tex]

1 - β² = (Δt'/Δt)²

Δt = √(Δt'/(1 - β²)) = √(0.00002568443 /(1 - 0.99999999964²)) ≈ 188.87 s.

Answer:

Other one is wrong, this one I got 100% on.

Explanation:

Protection – Protect the wounded area with a support or something similar. this means after an injury has happened, use tools or simple objects to cover and protect the injury so nothing else can harm or get into the injury.

Rest – Do not continue to exercise while your wound is healing. It may take a few weeks or months to recover. You may need crutches or a sling. This means take the time to give your body the rest and relaxation it needs in order to be strong and healthy again.

Ice – Wrap a bag of ice or a bag of frozen peas in a towel and apply it to the wounded area for 15–20 minutes every two to three hours. As it states, ice can help recover an injury or make the swelling and pain go away, this will also help you stay relaxed and calm

Compression – Apply elastic compression bandages to the wounded area during the day to reduce swelling. Compression greatly helps stop any blood or fluid from leaving the body, using the compression method closes an open wound and uses pressure to keep the wound closed

Elevation – Make sure the injured body part is elevated above the height of your heart as much as possible to help reduce swelling. This is also important, elevation helps keep swelling down and help keeps unwanted blood out of the wound

a) F = 353.2 N

b) [tex]F_{f} = 147.2 N [/tex]

   a = 4.21 m/s²

Explanation:

a) The minimum force necessary to start moving the box s given by:       

[tex]\Sigma F = 0[/tex]

[tex] F - \mu_{s}N = 0 [/tex]

[tex] F = \mu_{s}mg [/tex]

Where:

F: is the force applied to move the box

μs: is the static coefficient of friction = 0.6

In order to solve this problem, we must remember that the x & y components of a vector can be determined using the cosine and sine function of the angle.

Fx = 10*cos (48) = 6.69 [N]

Fy = 10*sin (48) = 7.43 [N]

Answer:

There is a logical explanation for that.

Explanation:

Human activities such as lighting campfires and discarding lit cigarettes are responsible for starting fires, hotter weather makes forests drier and more susceptible to burning.

Rising temperatures, a key to climate change, evaporate moisture from the ground, drying out the soil, and making vegetation more flammable. At the same time, winter snowpacks are melting a month earlier, meaning forests are drier for longer periods.

As drought and rising heat continue with rising greenhouse gas emissions, there will be more expected wildfires in the years ahead, especially with the fire seasons getting longer.

Answer:

1) For the swung puck tied to the string that has a mass m₁ and having another mass m₂ attached to the string that passes through a hole in the table, such that m₂ > m₁

The swung puck rotating on the table is kept in the circular motion on the table by the centripetal force acting towards the center of its rotation along the string, which is given by the amount the weight of m₂ exceeds m₁, in the same way a planet moving around the Sun is kept in its orbit by the gravitational attraction between the planet and the Sun.

2) i) The forces acting on the puck are;

a) The centripetal force in the string, acting inward, towards the center of rotation provided by the weight of m₂

b) The centrifugal force of the puck, acting outward, tending to continue its motion in a straight line

ii) The forces acting on the planet are;

a) The force of gravitational attraction between the planet and the Sun, acting towards the Sun, such that, the planet revolves around the Sun

b) The centrifugal force of the planet, acting outward, tending to move in a linear or straight path

Explanation:

Forces on Puck  Swung

Centrifugal Force (Outwards from  puck swung  )

Tension( Towards the center)

Forces on the Planet

Centrifugal Force (Outwards from  Planets  )

Gravitational Force ( Inwards towards Sun )

Let us suppose that the

The  puck swung is connected with a center at a distance of radius  r

so it is revolving around the point  just like planets revolve around the Sun.

The Centrifugal  Force and Gravitational Force  causes the planetary motion around the sun.

The Centrifugal force is an outward force  and is observed  from the accelerated frame of reference , In our case Planet and  puck swung are    the accelerated frame of references.

The Gravitational Force between the Sun and the planets  (directed towards Sun) is balanced by Centrifugal Force.

Let us consider that the string of  puck swung has negligible mass

So the Tension which is directed towards the center will provide the  force to counterbalance the centrifugal  force acting on puck swung.

So Tension will act towards the center in case of puck swung and centrifugal force will act outwards.

La potencia o consumo en watt de una ampolleta conectada a una red de energía eléctrica doméstica monofásica de 220 volt, si la corriente que circula por el circuito de la ampolleta es de 0.45 ampere, es 99 Watts.

Explanation:

Potencia es la velocidad o rapidez con la que se consume la energía. Siendo la energía la capacidad que tiene un mecanismo o dispositivo eléctrico cualquiera para realizar un trabajo, también se puede definir potencia como la energía desarrollada o consumida en una unidad de tiempo. Su unidad de medida es el Watt.

La ley de Watt establece que la potencia eléctrica P suministrada por un elemento de circuito, es directamente proporcional al producto entre la tensión de la alimentación V del circuito y la intensidad de corriente I que circula por él.  

Matemáticamente, la ley de Watt se expresa:

P = V.I

donde V es medida en Volt e I es medida en Ampere.

En este caso:

Reemplazando:

P= 220 volt* 0.45 ampere

P= 99 Watts

La potencia o consumo en watt de una ampolleta conectada a una red de energía eléctrica doméstica monofásica de 220 volt, si la corriente que circula por el circuito de la ampolleta es de 0.45 ampere, es 99 Watts.
