Answer:
B. Golgi body
Explanation:
The Golgi body is the region where proteins are modified, packaged, and transported to the appropriate location, usually outside of the cell.
The cytoplasm is the intracellular fluid/space, the mitochondrion produces energy, the ribosome produces proteins, and the vacuole is a storage organelle.
The Answer is B , Because the golgi body stores stuff for later use.

A runner moves at an average speed of 3.0 m/s and covers 9.5 km. In seconds, how long does the run take?
28.5 s
29.0 s
3.16 s
3200 s
Answer:
3200 seconds
Explanation:
If he ran at 3 m/s for 28.5 seconds, he would have run 85.5 meters
29 seconds would be 87 meters run not 9.5 km
Describe the nucleus of the atom.
Answer:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger Marsden gold foil experiment. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.

A car starts from rest and accelerates for 2.9 s
with an acceleration of 2 m/s2.
How far does it travel?
Answer in units of m.
Answer:
[tex]a \: = \frac{v - u}{t} [/tex]
2 = v-0/2.9
2× 2.9 = v
v = 5.8 m/s
[tex]v \: = \frac{d}{t} [/tex]
5.8 = d/2.9
5.8×2.9 = d
d = 16.82 m
Molten (melted) iron and carbon monoxide are produced in a blast furnace by the reaction of iron(III) oxide and pure carbon. Fe2O3 + 3C ---> 2Fe + 3CO If 4 moles of Fe2O3 are used, how many moles of Carbon Monoxide (CO) can be produced?
Answer:
Explanation:
Fe₂O₃ + 3C ---> 2Fe + 3CO
1 mole 3 moles
From the balanced equation above , we see that , 1 mole of Fe₂O₃ reacts with carbon to form 3 moles of CO .
So , 4 moles of Fe₂O₃ will react with carbon to form 3 x 4 moles of CO .
moles of CO formed = 3 x 4 moles = 12 moles.

Together, Denise and her brother painted a total of 3 5 of a living room wall. Denise painted 3 5 of that part, and her brother painted the rest. What part of the living room wall did Denise paint herself? Denise paintedof the living room wall.
Answer:
9 ÷ 25
Explanation:
The computation of the part of the living room that should be painted is shown below:
= Living room painted × rest of the part painted
= 3 ÷ 5 × 3 ÷ 5
= 9 ÷ 25
We simply multiplied with the above two items and the same is to be considered
hence, the part of the living room i.e. painted is 9 ÷ 25
The same is to be considered
mechanical advantage of a simple machine is 4,what does it mean?
Answer:
I hope this answer is correct
Explanation:
The mechanical advantage of a machine is 4. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.

How are Covalent bonds formed?
I believe it is introduced when the variation between the electronegativities of only two atoms is way too small for any transfer to take place to produce new ions.
Considering the definition of covalent bond, Covalent bonds are formed when valence electrons of non-metallic elements are shared and hold this elements together, forming a molecule.
Covalent bondThe covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule.
Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.
SummaryCovalent bonds are formed when electrons in the outermost level of non-metallic elements are shared and hold this elements together, forming a molecule.

Explanation:
An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark. What was the total distance the ant traveled?
Given :
An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west.
It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark.
To Find :
The total distance the ant traveled.
Solution :
Total distance travelled by ant = (distance between 14 and 20 inch mark) +
(distance between 20 and 16 inch mark)
Total distance = (20-14 ) + ( 20-16) = 6 + 4 = 10 inch.
Therefore, total distance the ant traveled is 10 inch.
Hence, this is the required solution.

A vertical rope is attached to an object that has a mass of 40.0 kg and is at rest.
The tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is
Answer:
239.2 N
Explanation:
Given that a vertical rope is attached to an object that has a mass of 40.0 kg and is at rest.The tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is
The tension in the rope and the weight of the mass will be acting in an opposite direction.
T - mg = ma ....... (1)
Where acceleration a = Velocity/ time
a = 3.5 / 0.7
a = 5 m/s^2
Substitutes acceleration a into the equation 1 above.
T - 40 × 9.8 = 40 × 5
T - 39.2 = 200
T = 200 + 39.2
T = 239.2N
Therefore, the tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is 239.2N
Answer:
The answer is T=592 N
Explanation:
Fw= 392N
a=v/t, so a=3.5ms^-1/0.7s
a=5ms^-2
Fnet=ma
T-Fw=ma
T-392N=40kg(5ms^-2)
T=592N

Can an object have a positive position, but a negative velocity? Explain your reasoning.
Answer:
Yes
Explanation:
A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.
So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity
Which of these equations will you used to find the final velocity if the initial
velocity and time is given? *
Answer:
2.77 would be the answer for this
How is acceleration related to force when mass is constant, according to Newton's second law of motion?
Answer:
According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.
[tex]f = ma[/tex]
[tex]a = \frac{f}{m} [/tex]
f = force
m = mass
a = acceleration
According to Newton's second law of motion, acceleration is directly proportional to the force.
What is Newton's second law of motion?According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.
Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.
According to Newton's second law of motion, an object's acceleration is directly proportional to the force acting on it.

find weight of 45 kg at height 800 km from earth's surface?
Answer:
The weight is 348.4 N
Explanation:
Effect of the Altitude on the Acceleration of Gravity
The effect of gravity decreases with altitude because greater altitudes mean greater distances from the Earth's center.
The practical formula to calculate the gravity as a function of the altitude h is:
[tex]{\displaystyle g_{h}=g_{0}\left({\frac {R_{\mathrm {e} }}{R_{\mathrm {e} }+h}}\right)^{2}}[/tex]
Where go is the conventional gravitational acceleration = [tex]9.80665\ m/s^2[/tex]
R is the Earth's mean radius at the equator = 6,378 Km
h is the altitude.
At a height of h=800 Km, the acceleration of gravity is:
[tex]{\displaystyle g_{h}=9.80665 m/s^2\left(\frac {6,378 Km }{6,378 Km+800Km}}\right)^{2}}[/tex]
Calculating:
[tex]g_h=7.74\ m/s^2[/tex]
The weight is the product of the acceleration of gravity by the mass of the object, thus:
[tex]W=45\ Kg\cdot 7.74\ m/s^2=348.4\ N[/tex]
The weight is 348.4 N
