Use the Pythagorean theorem to answer this question. A paper airplane is thrown westward at a rate of 6 m/s. The wind is blowing at 8 m/s toward the north. What is the actual velocity of the airplane?2 m/s, northwest
10 m/s, northwest
14 m/s, northwest
48 m/s, northwest

Answers

Answer 1

Answer:

The correct answer to the question is : 10 m/s , northwest.

EXPLANATION:

As per the question, the velocity of wind V = 8 m/s towards north.

The velocity of the paper airplane is V' = 6 m/s towards west.

We are asked to calculate the actual velocity of the airplane.

By putting Pythagorean theorem, the actual velocity of the airplane is calculated as -

$V_(net)^2 =\ V^2+V'^2$

⇒ $V_(net)^2=\ 6^2+8^2$

⇒ $V_(net)^2\ =\ 100$

⇒ $V_(net)=\ √(100)\ m/s$

⇒ $V_(net)=\ 10\ m/s$ towards northeast.

Hence, the correct answer is 10 m/s , northwest.

Answer 2

Answer: 6^2 + 8^2 = 36 + 64 = 100

sqrt(100) = 10 m/s northwest

Answers

Resistance is the ratio of

(current between the same points).

It's expressed in units of Ohms, so the correct choice is "none of the above".

It's e. none of the above because electrical resistance is measured in ohms.

Which event can be excluded from a list of interactions among Earth's spheres?A solar flares
B volcanic eruption
C fracking for natural gas
D hurricane

Answers

Final answer:

Solar flares can be excluded from a list of interactions among Earth's spheres because they are not directly related to interactions among the geosphere, hydrosphere, atmosphere, and biosphere.

Explanation:

The event that can be excluded from a list of interactions among Earth's spheres is A solar flares. Solar flares are not directly related to interactions among Earth's spheres, which include the geosphere, hydrosphere, atmosphere, and biosphere.

On the other hand, volcanic eruptions, fracking for natural gas, and hurricanes are all examples of interactions among Earth's spheres. Volcanic eruptions involve the release of gases and materials from the geosphere into the atmosphere. Fracking for natural gas involves extracting resources from the geosphere and potentially impacting the hydrosphere. Hurricanes involve interactions between the atmosphere and the hydrosphere, resulting in powerful storms.

Therefore, the correct answer is A solar flares.

Hurricane is the answer

The _____ theory is the most accepted theory regarding the origin of the solar system. It suggests that our star, the Sun, was first created by a cloud of dust and gas.

Answers

The Nebular Hypothesis is the most accepted explanation of the origin of our solar system. It states that the Sun was formed by a massive cloud of dust and gas light-years across, and it was bigger than the actual sun itself. Most of the mass in the center formed the sun, and the rest expanded outward.

A. Nebular is the answer

A spherical electron cloud surrounding an atomic nucleus would best represent

Answers

The s, p, d, and f orbitals are the areas where electrons will be most likely found. These letters give us an idea of the shapes of these formed by the electron clouds. Going by this, a spherical electron cloud surrounding an atomic nucleus would best represent an;

a. s Orbital

The s Orbital has spherical symmetry and is located around the nucleus of an element.

As there becomes an increase in the energy levels, the size of the orbital increases, leading to the extension of the electrons further away from the nucleus.

The angular quantum number (l) of the s subshell is 0. When fixed into the equation; 2 (2l + 1), the maximum number of electrons that this subshell can hold is 2.

Answer:

a S orbital

Explanation:

Atomic orbitals is the place where we are most likely to find at least one electron, this definition is based on the equation posed by Erwin Schrödinger.

It is said that each electron occupies an atomic orbital that is defined by a series of quantum numbers s, n, ml, ms. In any atom each orbital can contain two electrons. It is possible that thanks to the function of the orbitals, the appearance that atoms can have is that of a diffuse cloud.

The orbitals s (l = 0) have a spherical shape. The extent of this orbital depends on the value of the main quantum number, so a 3s orbital has the same shape but is larger than a 2s orbital.

The orbitals p (l = 1) are formed by two identical lobes that project along an axis. The junction zone of both lobes coincides with the atomic nucleus. There are three orbitals p (m = -1, m = 0 and m = + 1) in the same way, which differ only in their orientation along the x, y or z axes.

The orbitals d (l = 2) are also formed by lobes. There are five types of d orbitals (corresponding to m = -2, -1, 0, 1, 2)

Friction causes kinetic energy to be converted into what energy

Answers

Friction causes kinetic energy to be converted into 'thermal energy'. The answer to this question is 'thermal energy'. An example would be if something is being rubbed against another object, there is friction and thermal energy will be produced. I hope this helps you on your assignment! You're welcome.

Final answer:

Friction causes kinetic energy to be converted into thermal energy.

Explanation:

Friction causes kinetic energy to be converted into thermal energy, among other forms of energy. When an object is in motion and experiences friction, the work done by friction is negative, which reduces the object's kinetic energy. This converted energy is often released as heat.
