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.

Answer: D) continue in the same direction with no change of speed.

In other words, the velocity of the object won't change.

A net force of 0 means that all forces acting on the object are in balance. If the object is in motion, then it stays in motion. If the object is at rest, then it stays at rest. This is newton's first law of motion describing inertia.

This is the answer. This answer also works on acellus

Answer:

F = 20.61 N

Explanation:

Given that,

Mass of the object, m = 2 kg

It is moving with a speed of 10 m/s

It is acted upon by a 5 N of friction.

The force of gravity acts in downward direction which is given by :

W = mg

W = 2 × 10 = 20 N

5 N of force is acting in horizonal surface.

The net force is given by the resultant of two vectors as follows :

[tex]F=\sqrt{20^2+5^2} \\\\=20.61\ N[/tex]

So, the net force acting on the object is 20.61 N.

The net force acting on the mass is equal to 13.6 Newton.

Given the following data:

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 [tex]m/s^2[/tex].

To calculate the net force:

First of all, we would determine the normal force acting on the mass.

Mathematically, the normal force is given by the formula:

[tex]F_N = mg[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]F_N = 2 \times 9.8[/tex]

Normal force = 19.6 Newton

To find net force:

[tex]Net\;force = 19.6 - 5[/tex]

Net force = 13.6 Newton.

Note: We subtracted because friction opposes the motion of an object and as such acts in opposite direction.

Answer:

101 J

Explanation:

Answer:

[tex]\boxed {\boxed {\sf 101 \ Joules}}[/tex]

Explanation:

Kinetic energy can be found using the following formula:

[tex]KE=\frac{1}{2}mv^2[/tex]

The mass of the baseball is 0.140 kilograms and the velocity is 38.0 meters per second.

[tex]m= 0.140 \ kg \\v= 38.0 \ m/s[/tex]

Substitute the values into the formula.

[tex]KE=\frac{1}{2} [0.140 \ kg][(38.0 \ m/s)^2][/tex]

First, evaluate the exponent.

[tex]KE=\frac{1}{2}(0.140 \ kg)(1444 \ m^2/s^2)[/tex]

Multiply the two numbers in parentheses together.

[tex]KE=\frac{1}{2}(202.16 \ kg*m^2/s^2)[/tex]

Multiply the fraction by the number, or divide the number by 2.

[tex]KE=101.08 \ kg*m^2/s^2[/tex]

Round to the nearest whole number. The 0 in the tenth place tells us we can leave the number as is.

[tex]KE\approx 101 \ kg*m^2/s^2[/tex]

1 kg*m²/s² is equal to 1 Joule. Therefore, our answer of 101 kg*m²/s² is equal to 101 Joules (J).

[tex]KE\approx 101 \ J[/tex]

The kinetic energy of the baseball is about 101 Joules.

The rock will hit the ground at 20.44 m from the point of the drop

Explanation:

Horizontal Motion

It occurs when an object is thrown horizontally from a height h at an initial speed v.

The range or maximum horizontal distance traveled by the object can be calculated as follows:

[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]

When the small rock is dropped from a car at speed v=32 m/s, it starts a curved path that ends up when the rock hits the ground. The height is h=2 m, thus the range is:

[tex]\displaystyle d=32\cdot\sqrt{\frac {2\cdot 2}{9.8}}[/tex]

[tex]\displaystyle d=32\cdot\sqrt{0.4082}[/tex]

[tex]d=20.44\ m[/tex]

The rock will hit the ground at 20.44 m from the point of the drop

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

Answer:

i. 1.84 m

ii. The ball's time in the air is 1.23s.

Explanation:

The ball moves upward (against the gravitational pull) with an initial velocity of 6 m/s.

I. Applying the third equation of free fall, the maximum height is;

[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2gs

where the variables have there usual meaning.

[tex]V^{2}[/tex] = 0 m/s, [tex]U^{2}[/tex] = 6 m/s, g = 9.8 m/[tex]s^{2}[/tex].

0 = [tex]6^{2}[/tex] - 2 x 9.8 x s

0 = 36 - 19.6s

⇒ 19.6s = 36

s = [tex]\frac{36}{19.6}[/tex]

 = 1.8367

 = 1.84 m

The maximum height of the ball is 1.84 m.

II. The time the ball was in air can be determined by,

time of flight, T = [tex]\frac{2USin A}{g}[/tex]

where U is the initial velocity of the ball, A is the angle of projection and g is the acceleration due to gravity.

U = 6 m/s, A = [tex]90^{o}[/tex] (since the ball is thrown vertically upward), and g = 9.8 m/[tex]s^{2}[/tex].

T = [tex]\frac{2 *6 Sin90^{o} }{9.8}[/tex]

  = [tex]\frac{12}{9.8}[/tex]

  = 1.2245

T = 1.23s

The ball's time in the air is 1.23s.

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.

Answer:

His speed, in metres per second, is approximately 10m/s. The correct option is B.

Explanation:

Speed is defined as the rate in which an object cover a distance in a given time. It is measured in meters per second ( m/s). From the question, the jogger covered a distance of 3Km which when converted to meter is 3000meters in a given time 5 minutes which is 300seconds. The calculation of his speed in meter per second is shown below:

Distance= 3Km to meters ( as 1000meters = 1Km). Therefore 3× 1000 = 3000m

Time= 5 minutes to seconds ( as 1 minute = 60 Seconds). Therefore 5× 60= 300.

Speed= distance/ time

= 3000/300

= 10m/s

Therefore his speed, in metres per second, is approximately 10.
