Jayden created a cell model using a glass bottle with a cork. He said that the cork could be opened to eliminate waste material that’s generated after digestion in the cell. A number of particles resembling organelles are in the bottle. Which organelle’s function will cause Jayden to open the cork to eliminate waste material?
A. chloroplast
B. cytoplasm
C. nucleus
D. lysosome
E. ribosome

Answers

Answer 1

Answer:

D. lysosome

Explanation:

A. chloroplast  - the role of the chloroplast is to trap light energy and perform photosynthesis

B. cytoplasm  - the cytoplasm is the fluid-filled space inside the cell

C. nucleus  - the nucleus houses the genetic material

D. lysosome  - This is the correct answer. Lysosomes trap and digest waste products in the cell and break them down into reusable components.

E. ribosome - the ribosomes are protein synthesis machines

Define what velocity means.

Answers

Decelerate sounds a lot like the word accelerate, but we know that the speed is decreasing, so it would have to be going down, getting slower, so whichever sounds like a good example of speed decreasing should be a good answer!

Two children are pulling and pushing a 30.0 kg sled. The child pulling the sled is exerting a force of 12.0 N at a 45o angle. The child pushing the sled is exerting a horizontal a force of 8.00 N. There is a force of friction of 5.00 N.


What is the weight of the sled?

(blank) N

What is the normal force exerted on the sled? Round the answer to the nearest whole number.

(blank) N

What is the acceleration of the sled? Round the answer to the nearest hundredth.

(blank) m/s2

Answers

Answer:

Explanation:

Find the diagram of the scenario in the attached file.

From the diagram, the weight = mass * acceleration due to gravity

mass of sled = 30.0kg

acc. due to gravity = 9.81m/s

weight of the sled = 30.0*9.81

weight of the sled = 294.3N

The normal reaction force R in the diagram will be gotten by resolving the 12N force along the vertical

Ry = 12sin45°

R = 12 * 1/√2

R = 12√2/√2

R = 6√2 N

R = 8.49N ≈ 9.0N

The normal force exerted on the sled is approximately is 9.0N

Get the acceleration

Using the formula [tex]\sum Fx = ma_x[/tex] where;

m is the mass of the sled = 30.0kg

[tex]a_x[/tex] is the acceleration of the sled

[tex]\sum Fx = 8 + 12cos45^0\\\sum Fx = 8 + 12(0.7071)\\\sum Fx = 8 + 8.49\\\sum Fx = 16.49N[/tex]

Substitute into the formula;

[tex]a_x = \frac{\sum Fx }{m} \\ a_x = \frac{16.49}{30}\\ a_x = 0.55 m/s^2[/tex]

Hence the acceleration of the sled rounded to the nearest hundredth is 0.55m/s²

1)A 1 kg brick is carried to up the Eiffel Tower to the 275 m platform. How
much gravitational potential energy does it acquire?

Answers

Answer:

The gravitational potential energy is 2,750 Joules

Explanation:

Given the following data;

Mass of brick = 1kg

Height of Eiffel Tower = 275m

Potential energy can be defined as the energy possessed by an object due to its position.

Mathematically, potential energy is;

[tex] P = mgh[/tex]

Also, we know acceleration due to gravity = 10m/s2

[tex] P = mgh[/tex]

[tex] P = 1 * 275 * 10 [/tex]

P = 2750 Joules.

Hence, the gravitational potential energy the brick acquired is 2750 Joules.

It is your parent's 25th Wedding Anniversary and you thought it would be special to throw them a surprise party. Your entire family is up north at your Traverse City cottage (240 miles from your home) and you plan on waking up early Saturday morning to drive home and set up for the party. You wake up at 10:00 am to head out but to your surprise your parents decide on leaving at 11:00 am instead of 1:00 pm like they originally planned. Your father ALWAYS drives 60 miles per hour on the expressway and it will take you about 2 hours to set up for the party. How fast must you drive in order to get home in enough time to make the surprise a success? Show your work.

Answers

Answer:

120 miles per hour.

Explanation:

We need to find the time it takes my parents to drive home from the cottage. Since my father drives at 60 miles per hour, and the cottage is 240 miles from our home, and distance = speed × time. So, time = distance/speed = 240 mi/60 mi/h = 4 h.

So, it will take my father 4 hours to drive home from the cottage.

Since I have 2 hours to prepare for the party, the time left for me to drive to the cottage is 4 - 2 hrs = 2 hrs.

So, I'm supposed to drive to the cottage in at most 2 hours.

The speed at which I must drive in this time period is thus,  speed = distance/time = 240 miles/2 hours = 120 miles per hour.

So, I must drive at a minimum speed of 120 miles per hour.

Answer: The options are not given.

Here are the options.

A. energy is continuously created.

B. energy is continuously destroyed.

C. energy exists in a field.

D. all of these

The correct option is C.

Energy exists in a field.

Explanation:

Energy is the ability to do work or the property i.e force or power that is moved to an object so that it can perform work.

Energy exists in a field because a field is a region in which each area is affected by a force or power on an object . For example a paper clip placed on a magnetic field require a force or power to be able to attract or repel magnets.

An electric field surronds an electric charge when another particle is around it, it uses energy to either attract or repel the object e.t.c.

Therefore energy exists in field.

Answers

Answer:

b

Explanation:

The factor that is most likely to be responsible for the changes observed in the world's rainforest is human activities.

There has been a surge in the human population leading to an increased need for housing, foods, and other infrastructures. All these needs are directly or indirectly provided by the forest. Hence, the more the population of human expands, the more pressure that would be exerted on the rainforest and, indeed, other forests of the world.
