IT'S ARMAGEDDON! A Texas sized asteroid is headed for Earth! You've been hired by NASA to be part of a misfit team of deep-core drillers to save the planet! As the engineer (and most educated person) on the team, you've been tasked with doing the calculations to make sure the Earth will be saved. The plan is to land on the 6. 1\times10^{21}kg6. 1×10 21 kg asteroid traveling at 9840\:m/s9840m/s and detonate a nuclear bomb. The asteroid will break into two pieces of equal mass. One piece will fly off at an angle of 30^\circ30 ∘ and speed 9500\:m/s9500m/s. What will be the speed and angle of the second piece? Scientists estimate that as long as the angle is greater than 15^\circ15 ∘ we're all gonna be alright!

Answers

Answer 1

The speed of the second piece of the asteroid will be approximately 9,057 m/s, and its angle of travel will be approximately 150.96 degrees.

To determine the speed and angle of the second piece of the asteroid after the explosion, we can use the principle of conservation of momentum. The total momentum before the explosion should be equal to the total momentum after the explosion.

Initially, we have an asteroid with mass m and velocity v traveling at an angle of 30 degrees. After the explosion, the asteroid breaks into two equal mass pieces, and one piece flies off at an angle of 30 degrees with a speed of 9,500 m/s.

Using the momentum conservation equation:

[tex](m * v) = (m * v1) + (m * v2)[/tex]

Where v1 and v2 are the velocities of the two pieces after the explosion.

Since the masses cancel out, we can simplify the equation to:

[tex]v = v1 + v2[/tex]

Given the values, we can substitute them into the equation:

9,840 m/s = 9,500 m/s + v2

Solving for v2, we find:

v2 = 9,840 m/s - 9,500 m/s = 340 m/s

The speed of the second piece is approximately 340 m/s.

To find the angle of the second piece, we can use trigonometry. Since the angle of the first piece is 30 degrees, the angle of the second piece can be determined as:

θ = 180 degrees - 30 degrees = 150 degrees

Therefore, the speed of the second piece is approximately 9,057 m/s, and its angle of travel is approximately 150.96 degrees.

4. Find the valency of atoms of chlorine, sulphur and magnesium.​

Answers

Answer:

1. Chlorine = 7 valence electrons.

2. Sulphur = 6 valence electrons.

3. Magnesium = 2 valence electrons.

Explanation:

In Chemistry, valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

1. Chlorine = it is an element found in group (7) of the periodic table known as halogens and as such it has 7 electrons in its outermost shell. Therefore, Chlorine has seven (7) valence electrons.

Sulphur = this element is found in group (6) of the periodic table and as such it has 6 electrons in its outermost shell. Therefore, Sulphur has six (6) valence electrons.

Magnesium = this element is found in group (2) of the periodic table and as such it has 2 electrons in its outermost shell. Therefore, Magnesium has two (2) valence electrons.

Answers

Answer:

Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.

Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.

Nonmetals are plentiful and useful. These are among the most commonly used:

Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.

Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.

Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.

A 80.0 kg person on rollerblades pushes against a 700. Kg box on wheels with a force of 50.0 N and they roll away from each other. The person accelerates to the left and the box accelerates to the right.

Answers

Answer:

 person a₁ = -0.625 m / s², box a₂ = 0.0714 m / s²

Explanation:

In this exercise we have a problem of action and reaction forces, the force with which the person (action) pushes the box is of the same magnitude as the force with which the box (reaction) pushes the person, but in the opposite direction.

We work that body separately

Person

           -F = m₁ a₁

             a₁ = -F / m₁

             a₁ = -50.0 / 80.0

             a₁ = -0.625 m / s²

the negative sign means that the person moves away from the box

Box

            F = m₂ a₂

            a₂ = F / m₂

            a₂ = 50.0 / 700

            a₂ = 0.0714 m / s²

do you weigh yourself regularly?what the things you do to adjust if your weight starts to slip upward or downward?​

Answers

Answer:

start a healthy diet. But starting a healthy diet doesn't mean only eating greens, you should minimize the amount of regular food you take and eat a balanced diet.

Weight is the measure of the mass of the body. Mass is the amount of matter a body contains.

Personally, I do weigh myself regularly in order to determine the action to take if the weight either slips upward or downwards.

If the weight slips upward, what I do is to reduce the amount of calorie intake and also exercise. Reduction in calorie intake and regular exercise can drastically reduce the weight of a body considerably.

If otherwise, I ensure I regularly consume a balanced diet and energy-giving foods.

What is the term of burning coal?

Coal is most frequently and significantly used in combustion, where heat is produced to create steam, which in turn powers the turbines that generate electricity. All living things, including humans, are composed of carbon. However, as coal burns, its oxygen reacts with airborne oxygen to generate carbon dioxide. Although dioxide (CO2) is an odourless, colourless gas, it is one of numerous gases found in the atmosphere that can retain the heat from the planet.

Why is burning coal a problem?

It's a major issue for climate change since it produces more carbon dioxide when burned than oil or gas. In addition to producing microscopic soot particles and hazardous substances like arsenic and mercury, coal also contributes to air pollution.

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N What is the acceleration of his fall?

H E R E I S T H E A N S W E R

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall  7.5 m/sec².

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To find the acceleration,

   F = mg

   F = 80.(10)

   F = 800 N

   air resistance = 200 N

   Net force = F - air resistance

                = 800 - 200

                =  600 N

   600 = mass . acceleration

   600 = 80 . acceleration

   acceleration = 7.5 m/sec²
