Answer:

Design 2

Explanation:

I had this same question

My answer:

"Design 2 is the well-designed one, because the air molecules are the most compact and could protect the individual better than 1,3,and no air bag."

<h3>What is the Earth system?</h3>
  • The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the conditions we are accustomed to.
  • The rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle, and the energy cycle are a few examples found in the Earth system.
  • The major Earth circulation processes that move water, carbon, and nutrients renew essential elements for life and contribute to climate control. The continents, atmosphere, oceans, ice, and life on Earth are dynamic elements that constantly change and interact in a wide variety of ways.
  • A system is made up of four independent spheres. A change in one sphere may result in another change because the spheres interact. Fields are plowed by humans (biosphere) using farm equipment made of geosphere materials, while plants are watered by precipitation (hydrosphere) brought by the atmosphere.

1. Is the collision between the ball and the pendulum elastic or inelastic? Justify your answer by calculating the kinetic energ
Nitella [24]

Answer:

So energy is not conserved and inelastic shock

Explanation:

In the collision between a bullet and a ballistic pendulum, characterized in that the bullet is embedded in the block, if the kinetic energy is conserved the shock is elastic and if it is not inelastic.

Let's find the kinetic energy just before the crash

         K₀ = ½ m vₓ₀²

After the crash we can use the law of conservation of energy

Starting point. Right after the crash, before starting to climb

        Em₀ = K = ½ (m + M) v₂²

Final point. At the maximum height of the pendulum

       Em_{f} = U = (m + M) g h

Where m is the mass of the bullet and M is the mass of the pendulum

        Em₀ = Em_{f}

        ½ (m + M) v₂² = (m + M) g h

        v₂ = √ 2g h

Now we can calculate the final kinetic energy

       K_{f} = ½ (m + M) v₂²²

       K_{f} = ½ (m + M) (2gh)

The relationship between these two kinetic energies is

      K₀ / K_{f} = ½ m vₓ₀² / (½ (m + M) 2 g h)

      K₀ / K_{f} = m / (m + M)  vₓ₀² / 2 g h

We can see that in this relationship the Ko> Kf

So energy is not conserved and inelastic shock

2. A box filled with books has a mass of 15.0 kg. It is pushed across the floor with a constant force of 60.0 N. If the friction
sesenic [268]

Answer:

3 m/s^{2}

Explanation:

ΣF=ma

The two forces at play are the force applied and the force due to friction. As they are opposing forces set the direction being pushed as the positive in the x direction. the equation you come out with is 60 - 15=(15)A (we know mass to be 15kg). Solve for 3 m/s^2.

How to find weight in science
Kaylis [27]

There are several different methods, depending on the particular situation.  A few that might occasionally be useful include:

-- Read the label on the package.

-- Measure the mass and multiply by the local acceleration of gravity.

-- Measure the mass AND the local acceleration of gravity, then multiply.

-- Place the object or sample on a bathroom scale.

-- Place the object on one end of a symmetrical see-saw.  Through trial and error, determine the weight required on the other end to balance the system.
