Answer:
F= 11.76 kn
Explanation:
The rocket engines apply a constant upward force of 15680 N.
What is force?Force can be said as the amount of pressure that is applied ob an object. One can easily determine the mass and the velocity to find the force that is applied to an object.
Gravitational acceleration which will be represented by g = 9.8 m/s2
Mass of the rocket which will be represented by M = 400 kg
Constant upward force that is applied on the engine of the rocket which will be represented by F
The height through which engines accelerate the upward force upon the rocket will be represented by h = 100 m
Work done by the engine which will be represented by W
W = Fh
Maximum height well above the surface, this data will represent the rocket reaches which will be represented by H
The work completed with the help of the engine on the rocket is equal to the potential energy gained with respect to maximum height.
W = MgH
Fh = MgH
F(100) = (400)*(9.8)*(400)
F = 15680 N

On a test flight, a rocket with mass 400 kg blasts off from the surface of the earth. The rocket engines apply a constant upward force F until the rocket reaches a height of 100 m and then they shut off. If the rocket is to reach a maximum height of 400m above the surface of the earth, what value of F is required? Assume the change in the rockets mass is negligible.

Answer:
A. shadow
Explanation:
I took the test on edge
Shadow is the area of dark created when an object blocks light. The correct option is a.
A shadow is a dark area or shape cast by an object that stands between a light source and a surface.
When an object blocks light, it prevents light from reaching the surface behind it, resulting in a dark area the shape of the object.
This is what is commonly known as a shadow. Shadows are an important element in art, photography, and other visual media because they can create the illusion of depth and three-dimensional space while also adding drama and interest to a composition.
Shadows can also be used to add contrast and highlight specific elements in an image or scene.
Thus, the correct option is a.

you want to arrange digits 0 to 9 such that 1 and 2 always have 2 digits between them
We want to arrange digits 0 to 9 such that 1 and 2 always have 2 digits between them (we want to find the number of different combinations to do this).
There are 564,480 ways of arranging the digits 0 to 9 in such a way that there is always 2 digits between 1 and 2.
Now let's see how to get the number of combinations.
We have 10 numbers to order, so we have 10 places to put these numbers.
_ _ _ _ _ _ _ _ _ _
Let's start by assuming that the first number is the 1
1 _ _ _ _ _ _ _ _ _
Because 1 and 2 must have 2 digits between them, we put the 2 in the third place
1 _ _ 2 _ _ _ _ _ _
Now in the other 8 places we can put any of the other 8 numbers in any order, The number of combinations is just given by:
8! = 8*7*6*5*4*3*2*1 = 40,320
Now we also need to take in account the permutations of the 1 and the 2.
First, these two can permute (so the 2 goes first and then the 1) so there is a factor 2.
Also, we fixed the first one at the first position, but it could be in the second, third, fourth, fifth, sixth or seventh position, so there is also a factor 7.
Then the total number of combinations is given by:
2*7*40,320 = 564,480
This means that there are 564,480 ways of arranging the digits 0 to 9 in such a way that there is always 2 digits between 1 and 2.

an equation for the line tangent to the graph of the differentiable function f at x=2 is y=9x−12. which of the following statements must be true?
The true statements is B that comprises of option 1 and option 2 which are y(0) = -12 and y(2) = 6
From the given information, the equation y = 9x + 12 which is tangent to some function F when x = 2. To get the accurate value of our function we shall make x=0 and x = 2. Lets solve functions at these values of x:
X = 0
y = 9x - 12
y = 9(0) - 12
y = 0 - 12
y = -12
X = 2
y = 9x - 12
y = 9(2) + 12
y = 18 - 12
y = 6
Conclusively, we can say that The true statements is B that comprises of option 1 and option 2 which are y(0) = -12 and y(2) = 6

Which type of burn is BEST described as having reddish skin, white border, and some pain? A. first-degree burn B. second-degree burn C. third-degree burn D. forth-degree burn Please select the best answer from the choices provided. A B C D
Answer:
The correct answer to this equation is A.
Explanation:
~Hope this helps :)
Second-degree burns also referred to as partial-thickness burns, are characterized by reddened skin with a white or pale border. Therefore option B is correct.
These burns affect both the outer layer of skin (epidermis) and a portion of the underlying layer (dermis).
The reddening of the skin is due to inflammation and increased blood flow, while the white or pale border results from the destruction of skin cells in the affected area.
Second-degree burns typically cause pain due to the involvement of nerve endings in the dermis. Blisters may also develop.
Unlike first-degree burns, which affect only the outermost layer of skin, second-degree burns involve deeper tissue layers, making them more severe and requiring appropriate medical attention for proper care and healing.
Therefore option B is correct.

on january 1, 2017, a subsidiary sold equipment to its parent for $520,000. the subsidiary's original cost was $200,000 and as of january 1, 2017, $20,000 in depreciation had been recorded on the subsidiary's books. at the date of sale, the equipment had a 10-year remaining life, straight-line. it is now december 31, 2021 (5 years since the sale), and the parent still holds the equipment. in the consolidation eliminating entries for 2021, depreciation expense is reduced by
Answer:
Explanation:
Given:
Selling cost of equipment = $520,000
Original cost of the equipment = $200,000
Depreciation of asset = $20,000
The net amount of the Equipment = Original cost - Accumulated Depreciation
The net amount = $200,000 - $20,000 = $180,000
The Profit on Sale of the Equipment = Selling cost - The net amount
= $520,000 - $180,000
= $340,000
The equipment account (gross cost) is reduced by a net amount of $340,000 .

Why do lunar and solar eclipses not happen every month? Eclipses only occur during full and new moons. Earth rotates around its axis faster than the moon. The moon and Earth only travel through the penumbras. The tilt of the moon’s axis does not allow for monthly alignment.
The lunar and solar eclipses do not happen every month because the tilt of the moon’s axis does not allow for monthly alignment. It is for that reason we cannot observe a lunar/solar eclipse every month.
A solar eclipse occurs when the Moon moves between Earth and the Sun.
Moreover, a lunar eclipse happens when Earth moves between the Sun and the Moon, thereby partially or totally shadowing the Moon.
The Moon's orbit the Earth lies in a plane tilted by 5.15° with regard to the plane that Earth's orbit about the Sun.
If the Earth and Moon orbit on exactly the same plane around the Sun, then we could observe both a lunar eclipse and solar eclipse every month.
