What does the slope on a velocity-time graph measure?

Ribosomes, endoplasmic reticulum, vesicles, and the Golgi apparatus are the organelles present in the eukaryotic cell. They are involved in various roles and functions involving proteins.

Ribosomes are the organelles involved in the transcription and translation process to synthesize proteins and transport them from ER to the vesicles. The endoplasmic reticulum (ER) is a membraneous structure that along with ribosomes is involved in lipid and protein synthesis.

The proteins synthesized from ER are transported to the Golgi body through the vesicles. They even eliminate the waste from the cell. The Golgi apparatus receives proteins from ER and then packs, modifies, and transports them to the target location.

Therefore, the ER, ribosomes, Golgi, and vesicles are involved in protein synthesis and transportation.

Answer:

a. 6.39 s b. 255.6 m c. 62.6 m/s

Explanation:

a. Find the time it takes to hit the ground.

Using y = ut + 1/2gt² where y = height of cliff = 200 m, u = initial vertical velocity of ball = 0 m/s, g = acceleration due to gravity = 9.8 m/s² and t = time taken for ball to hit the ground.

So, substituting the values of the variables into the equation, we have

200 m = 0 m/s × t + 1/2 × 9.8 m/s² × t²

200 m = 0 + (4.9 m/s²)t²

200 m = (4.9 m/s²)t²

dividing both sides by 4.9 m/s², we have

t² = 200 m ÷ 4.9 m/s²

t² = 40.82 s²

taking square root of both sides, we have

t = √(40.82 s²)

t = 6.39 s

b. Find the RANGE, distance traveled horizontally.

The range is the horizontal distance traveled by the ball, R = vt where v = horizontal velocity of ball = 40 m/s and t = time taken for ball to hit the ground = 6.39 s

So, R = vt

= 40 m/s × 6.39 s

= 255.6 m

c. Find the final vertical velocity.

Using v = u - gt where u = initial vertical velocity of ball = 0 m/s, v = final velocity of ball, g = g = acceleration due to gravity = 9.8 m/s² and t = time taken for ball to hit the ground = 6.39 s.

So, substituting the values into the equation, we have

v = 0 m/s - 9.8 m/s² × 6.39 s

v = -62.62 m/s

v ≅ -62.6 m/s

Answer:

[tex]\boxed {\boxed {\sf 6 \ meters \ per \ second}}[/tex]

Explanation:

Speed can be found by dividing the distance by the time.

[tex]s=\frac{d}{t}[/tex]

The distance is 18 meters and the time is 3 seconds.

[tex]d= 18 \ m \\t= 3 \ s\\[/tex]

Substitute the values into the formula.

[tex]s=\frac{18 \ m }{ 3 \ s }[/tex]

Divide.

[tex]s= 6 \ m/s[/tex]

The speed of the puck is 6 meters per second.

To Find :

The acceleration of the car.

Solution :

We know, by equation of motion :

[tex]2as = v^2 -u^2\\\\a = \dfrac{v^2 -u^2 }{2s}\\\\a = \dfrac{(-10.9)^2 - ( -27.7)^2}{2\times ( -105 )}\\\\a = 3.088\ m/s^2[/tex]

Therefore, acceleration of the car is 3.088  m/s².

Answer:

1.55m

Explanation:

The formula for calculating the maximum height is expressed as;

H = u²/2g

u is the initial velocity

g is the acceleration due to gravity

Substitute

H = 1²/2(9.8)

H = 1/19.6

H = 0.051m

Since it is launched form a height of 1.5m, the height above the ground will be 1.5+0.051 = 1.55m

The answer would have to be 8.47 m/s/s because the backwards pull + the rate of speed it is going would have to be added to get the answer to compensate for the backwards pull

Answer:the nervous system

Explanation:

Anatomy vs Physiology as the Anatomy is the study of the structure of living organisms, while Physiology is the study of the function of living organisms.

Nervous System the nervous system integrates and controls the body's functions through electrical and chemical signaling. Anatomy focuses on the physical makeup of living organisms and their components, such as organs, tissues, and cells.

This includes the external and internal structures of the body, as well as the relationships between these structures. On the other hand, Physiology examines how living organisms perform the functions necessary for life, such as respiration, digestion, circulation, and movement.

Physiology explores the processes and mechanisms behind these functions, including biochemical reactions, electrical and mechanical events, and hormonal regulation.

The nervous system consists of the brain, spinal cord, and a network of nerves that extend throughout the body. It is responsible for collecting, processing, and transmitting information about the internal and external environment to the rest of the body.

The nervous system also regulates the activity of other systems in the body, such as the endocrine, cardiovascular, and respiratory systems.

Therefore, the potential Difference will be 4V.

Answer:

Force = 35 N

Explanation:

From Newton's third law of motion, the boy must apply a force greater than the weight of the sled to lift it.

weight of sled = mg

where m is its mass and g the force of gravity on it.

weight of sled = 50 N

Force applied by the boy on the sled = 15 N

Since the force applied on the sled by the boy is lesser than the weight of the sled, then;

Force that the sled exerts on the student = 50 - 15

                                             = 35 N

The force exerted by the sled on the student is 35 N.

Answer:

K.E = 100 J

Final P.E = 100 J

Explanation:

The kinetic energy of any object can be given by the following formula:

[tex]K.E = (\frac{1}{2})mv^{2}[/tex]

where,

K.E = Kinetic Energy

m = mass of ball = 2 kg

v = speed of ball

Initially, v = 10 m/s. Therefore, the initial K.E is given as:

[tex]K.E = (\frac{1}{2})(2\ kg)(10\ m/s)^{2}[/tex]

K.E = 100 J

Now, at the highest point the K.E of the ball becomes zero. because the ball stops for a moment at the highest point and its velocity becomes zero. So, from Law of Conservation of energy:

Initial K.E + Initial P.E = Final K.E + Final P.E

Initial P.E is also zero due to zero height initially.

K.E + 0 = 0 + Final P.E

Final P.E = 100 J

Answer:

Option (4)

Explanation:

Given polynomial is,

P(x) = 1x³ - 7x² + 2x + 40

If (x - 5) is a factor of the given polynomial,

Synthetic division by x = 5,

5 |  1    -7     2     40

    ↓    5   -10   -40

     1    -2    -8      0

Therefore, factored form of the polynomial will be,

P(x) = (x - 5)(x²- 2x - 8)

Now we further factorize the expression (x² - 2x - 8),

(x² - 2x - 8) = x²- 4x + 2x - 8

                  = x(x - 4) + 2(x - 4)

                  = (x + 2)(x - 4)

Now fully factored form of the polynomial will be,

P(x) = (x - 5)(x + 2)(x - 4)

Therefore, remaining factors of the polynomial other than (x - 5) are (x - 4)(x + 2)

Option (4) will be the correct option.

Answer:

The Enlightenment.

Explanation:

The Enlightenment took place during the eighteen century and it typically involved a period of philosophical, cultural and intellectual movement in which ideas on nature, reason, humanity and God were emphasized on greatly over science and superstition through meetings that were held at coffeeshops, scientific academies, literary salons, masonic lodges, etc. Some of the influential philosophers of the enlightenment were Adam Smith, John Locke, Jean Jacques Rousseau, David Hume, Baruch Spinoza, Montesquieu, Hugo Grotius, Denis Diderot, Gottfried Wilhelm, Cesare Beccaria, Immanuel Kant etc. The enlightenment was also known as the age of reason or the age of enlightenment.

Hence, the enlightenment was a period in European history when many educated people stressed the importance of learning and reasoning; education was considered the key to understanding and solving society's problems.

Answer:

a = - 0.209 [m/s²]

Explanation:

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

∑F = m*a

We will take the positive forces to the right and the negative forces to the left.

[tex]155-277+113=43*a\\-9=43*a\\a = - 0.209[m/s^{2} ][/tex]

The negative sign means that the box accelerates in a negative direction to the left.

Answer:

-180 V

Explanation:

Given that,

No. of turns, N = 150

If the field increases uniformly from 0.00 T to 0.95 T and each coil of wire has an area of 1.4 m²

The coil will move perpendicular through a uniform magnetic field in 1.1 s.

We need to find the magnitude of the induced emf in the coil. The formula for the induced emf is given by :

[tex]\epsilon=\dfrac{-d\phi}{dt}\\\\=\dfrac{-d(BA)}{dt}\\\\=-A\dfrac{dB}{dt}[/tex]

Put all the values,

[tex]\epsilon=-NA\dfrac{dB}{dt}\\\\=-150\times 1.4\times \dfrac{0.95-0}{1.1}\\\\=-181.36\ V[/tex]

Out of four options, induced emf is (-180 V)

So, induced emf in the coil is (-180 V). Hence, the correct option is (c).
