Answers

Answer 1

Answer:

A different answer to this is AI

Explanation:

Answer 2

Lithium, beryllium and boron are the elements that have an oxidation number of +3.

What is oxidation number?

Oxidation number refers to the total number of electrons that an atom gains or loses in order to get stability and formed chemical bond with another atom. Atoms that lose electron form positive charge.

So we can conclude that Lithium, beryllium and boron are the elements that have an oxidation number of +3.

There are two tall slides at the newly opened theme park, a blue slide and a red slide. The slides have such a height that, if it weren't for friction and air resistance, riders would travel twice as fast at the bottom of the blue slide as they do at the bottom of the red slide. If the red slide is 8m tall, how tall is the blue slide?

Answers

Answer:

32 m

Explanation:

By energy conservation, total energy at the top of slide must be equal to the total energy at at the bottom.

therefore

mgh = (1/2)mv^2

v^2= 2gh

[tex]v = \sqrt(2gh)[/tex] ..............(1) i.e., velocity is a function of height of slide.

1st part

Let height of blue slide be H and height of red slide be h.

Let velocity of rider in blue slide= V and red slide= v

At the bottom of slide,

From equation (1)

therefore  

[tex]\frac{V^{2}}{v^{2}} = \frac{2gH}{2gh}[/tex]

Given, V= 2v  

[tex]\therefore  \frac{4v^{2}}{v^2{}} = \frac{H}{h}[/tex]

H = 4h

therefore, height of blue slide is 4 times that of red slide= 4*8=32 m

at terminal velocity what will be relationship between drag force and driving force​

Answers

Answer:

The answer to this question is given below in this explanation section.

Explanation:

                "relationship between drag force and driving force​"

The velocity at any time during the flight depends on the corresponding acceleration of the vehicle and the balance of forces acting of the vehicle.Forces acceleration and velocity are all vector quantities having both a magnitude and a direction.When describing the motion of an object caused by forces,one must account for both the magnitude and direction.The forces present during coasting flights are the drag and the weight.The weight is constant is magnitude and is always directed toward the center of earth.The magnitude of the drag change the square of the velocity.During ascent the drag is in the same direction as the weight .But during descent the drag opposes the weight.

For the descending rocket the next vertical external force  F is equal to the difference between the drag D and the weight W:

                  F=D-W

Newton's Second Law of Motion states that the force of an objects is the product of mass and acceleration.

Newton's Third Law of Motion states that when two objects interact, a pair of forces act on the objects, and they are equal and act in opposite directions.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combination is

Answers

Answer:

The equivalent resistance of the combination is R/100

Explanation:

Parallel Connection of Resistances

If resistances R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

It's known the 10 parts or resistance R/10 were connected in parallel, thus the electric resistance is:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}+...+\frac{1}{R/10}[/tex]

Note the sum consists of 10 equal terms. Operating on each term:

[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]

The sum of 10 identical fractions yields 10 times each fraction:

[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]

Solving for Re needs to take the reciprocal of both sides of the equation:

[tex]R_e=R/100[/tex]

The equivalent resistance of the combination is R/100

why water molecules are closer together in the liquid state than in the solid state.​

Answers

Answer:

because of the hydrogen bonds, as water molecules come together they stick to one another for a small, but significant amount of time. This slows them down, and holds them closer to one another. They become a liquid; a different state of matter where the molecules are closer and slower than in a gas.

Answer:

When water is in its solid-state, the water molecules are packed close together preventing it from changing shape.

Explanation:

In general, when considering the states of matter, solids are denser than liquids, and normally liquids are denser than gases.

A boxer pushes on a 25 kg heavy bag which is attached to the ceiling until it makes an angle of 36 degrees to the vertical. How much force must the boxer exert on the bag?

Answers

Answer:

198.20 N

Explanation:

Given that,

Mass of a heavy bag, m = 25 kg

The bag is attached to the ceiling until it makes an angle of 36 degrees to the vertical.

We need to find the force must the boxer exert on the bag. The force acting on the bag is given by :

[tex]F=mg\cos\theta\\\\=25\times 9.8\times \cos(36)\\\\=198.20\ N[/tex]

However, the role of Paul McCartney is often overlooked. John Lennon and Paul McCartney were in other bands together before the forming of the Beatles. In 1962, along with Ringo Starr and George Harrison, they formed the rock group known as "The Beatles." The group featured a modern rock that was new and popular during the period with John and Paul composing and doing the leads on most of the songs. They were backed by George on lead guitar and Ringo on drums. George and Ringo also assisted on backing vocals. When they first began playing, the main influence inside the band was John Lennon, who had an ability to compose songs at a moment's notice with an inspiration that others missed. He pushed the members of the band during their touring years and was able to achieve the best possible results from the group. However, McCartney was also a strong force in the group since Lennon many times asked for McCartney's advice about ideas for songs. McCartney wrote many of the group's biggest hit songs, and often, he didn't even ask for song writing credit. After the breakup, McCartney launched a successful solo career. He has released many recordings both in the United States and abroad. One accomplishment was his first classical piece, Liverpool Oratorio, which is no small feat considering that McCartney never learned to read music.Which text would most likely follow the same text structure as the passage?
