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.

We want to find the distance the train travels from the time the conductor applies the brakes until the train comes to a complete stop. Which kinematic formula would be most useful to solve for the target unknown? Choose 1 answer:
Answer:
The distance the train travels before coming to a (complete) stop = 40/81 km which is approximately 493.83 meters
Explanation:
The initial speed of the train u = 80 km/h = 22 2/9 m/s = 22.[tex]\bar 2[/tex] m/s
The magnitude of the constant acceleration with which the train slows, a = 0.5 m/s²
Therefore, we have the following suitable kinematic equation of motion;
v² = u² - 2 × a × s
Where;
v = The final velocity = 0 (The train comes to a stop)
s = The distance the train travels before coming to a stop
Substituting the values gives;
0² = 22.[tex]\bar 2[/tex]² - 2 × 0.5 × s
2 × 0.5 × s = 22.[tex]\bar 2[/tex]²
s = 22.[tex]\bar 2[/tex]²/1 = 493 67/81 m = 40/81 km
The distance the train travels before coming to a (complete) stop = 40/81 km ≈ 493.83 m.

A diver runs horizontally off the end of a diving board with an initial speed of 1.95 m/s. If the diving board is 2.00 m above the water, what is the diver's speed just before she enters the water
Answer:
V = 6.56 m/s
Explanation:
in order to find the speed of the diver before she enters we need to find the vertical component of its final velocity by using 3rd equation of motion:
2gh = Vy² - V₀y²
where,
g = 9.8 m/s²
h = height = 2 m
Vy = Vertical Component of Final Velocity = ?
V₀y = Vertical Component of Initial Velocity = 0 m/s
Therefore,
2(9.8 m/s²)(2 m) = Vy² - (0 m/s)²
Vy = √39.2 m²/s²
Vy = 6.26 m/s
Assuming negligible air friction, the x-component of the final velocity will be the same as the initial velocity:
Vₓ = V₀ₓ = 1.95 m/s
Hence, the final velocity will be:
V = √(Vₓ² + Vy²)
V = √[(1.95 m/s)² + (6.26 m/s)²]
V = 6.56 m/s

Here is the parallelogram rule in the file attached... Can someone please explain why the resultant force of these 2 vectors (30 N and 40 N) is 60 N? I know it's with an angle at 26ºC to the horizontal, so it wouldn't be 50 N. So how do you find this? How do you calculate the vectors when they are not straight lines shown. If someone is using this for an advantage of points, I'll report you. Thanks in advance :)
9514 1404 393
Answer:
sum the components, orsolve the triangleExplanation:
The most straightforward way to compute the resultant of two vectors is to add their x- and y- components. In the attached, we have labeled the 30 N force "B" and the 40 N force "A". Their respective (x, y) components are ...
A = 40(cos(0°), sin(0°)) = (40, 0)
B = 30(cos(62.72°), sin(62.72°)) = (13.75, 26.66)
Then the components of the resultant are ...
R = A + B = (40, 0) +(13.75, 26.66) = (53.75, 26.66)
Its magnitude is found from the Pythagorean theorem:
|R| = √(53.75² +26.66²) = 60.00
Its direction is found from the components using the arctangent function:
∠R = arctan(26.66/53.75) = 26.38°
In a sort of shorthand notation, ...
R = 60.0∠26.4°
__
Alternate solution
In order to perform the above calculation, you need to know the angle between the vectors. The other angle in the parallelogram is the supplement of this. So, you can find the resultant by solving the triangle OAR, where O is the origin. Angle A in that triangle will be 180° -62.72° = 117.28°. This gives you enough information to use the Law of Cosines.
OR² = OA² +AR² -2(OA)(AR)cos(A)
OR² = 40² +30² -2·40·30·cos(117.28°) ≈ 3600.0
|R| = √3600 = 60
Then you can find the angle AOR using the law of sines.
sin(AOR)/30 = sin(117.28°)/60
∠AOR = arcsin(sin(117.28°)/2) = 26.38°
So, you now know ...
R = 60.0∠26.4°

Why does the lens need to be thicker for viewing nearby objects?
Answer: To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly. To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.

A permanent magnet picks up an iron nail, magnetizing the nail. How is this system different from an electromagnet?
Answer:the nail is magnetized by a permanent magnet instead of by a solenoid with an electric current running through it
Explanation:
The permanent magnet magnetizing the nail will differently function like electromagnet, by utilizing the electric current through the iron. Hence, option (B) is correct.
The given problem is based on the concept and fundamentals of magnetization. The term magnetizations means that the density of magnetic dipole moments induced in a magnetic material, when it is placed near a permanent magnet.
In the given problem, the magnetization of iron nail takes place by passing the current through the nail.The electric current utilize the electric charge which responds the electric field. When the current carrying nail is placed beside the permanent magnet, the dipole set up and it will create a polarity for which the nail will now itself behave as a magnet.Thus, we can conclude that the permanent magnet magnetizing the nail will differently function like electromagnet, by utilizing the electric current through the iron. Hence, option (B) is correct.

Find the range of a projectile launched at an angle of 30° with an initial velocity of 20m/s.
Answer:
The range is 35.35 m
Explanation:
Projectile Motion
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the initial speed of the object, θ the initial launch angle, and [tex]g=9.8m/s^2[/tex] the acceleration of gravity, then the maximum horizontal distance traveled by the object (also called Range) is:
[tex]\displaystyle d={\frac {v_o^{2}\sin(2\theta )}{g}}[/tex]
The projectile was launched at an angle of θ=30° with an initial speed vo=20 m/s. Calculating the range:
[tex]\displaystyle d={\frac {20^{2}\sin(2\cdot 30^\circ )}{9.8}}[/tex]
[tex]\displaystyle d={\frac {400\sin(60^\circ )}{9.8}}[/tex]
[tex]d=35.35\ m[/tex]
The range is 35.35 m
ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.
In working this problem, assume the value of "g" to be 9.8 m/s2 with two (2) significant digits unless otherwise stated.

A motor with a resistance of 320 is connected to a voltage source. Four amps of current flows
in the circuit. What is the voltage of the source?
I
Answer:
V = 1280 [V]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the resistance by the current.
Therefore we have:
V = I*R
where:
V = voltage [V] (Units of volts)
I = current = 4 [amp]
R = resistance = 320 [ohms]
V = 4*320
V = 1280 [V]

How does the observed pitch of the buzzer change as it moves
observer?
pitch of the buzzer increased (higher tone) as it moves towards the observer
The pitch of the buzzer decreased (lower tone) as it moves towards the observer
The pitch of the buzzer stayed the same no matter where it was in relationship
to the observer
The answer is
Pitch of the buzzer increased (higher tone) as it moves towards the observer
The correct option that explains the change in the observed pitch of the buzzer as it moves towards the observer is;
A; pitch of the buzzer increased (higher tone) as it moves towards the observer
This is based on the concept of doppler effect which is defined as the change in frequency/pitch of a sound that is heard by an observer due to the fact that the sound source and the observer have different velocities with respect to the medium through the sound travels.Now, according to doppler effect, when the source of the sound moves towards the observer, the frequency will increase due to the fact that the time between successive sound waves is shortened. Thus, this means that the pitch will be higher. However, when the sound source moves away from the observer, the frequency would decrease due to the fact that the time between successive sound waves or the crest is now longer. Thus, the pitch will decrease.In conclusion, the pitch of the buzzer will increase as it moves towards the observer.
