The crumple zone help protect a passenger from injury by converting some of the kinetic energy possessed by the car into a controlled deformation, or crumpling when there is a crash.

<h3>What is impact?</h3>

The term impact refers to a large force that acts for a short time. Passengers in a vehicles sustain injuries after an accident due to the high impact of the crash.

As such, the crumple zone help protect a passenger from injury by converting some of the kinetic energy possessed by the car into a controlled deformation, or crumpling when there is a crash.

What is the resistance of a 15 ampere current with 8 volts of potential difference?
Alex Ar [27]

Answer:

Resistance in circuit = 0.53 ohm (Approx.)

Explanation:

Given:

Flow of current in circuit = 15 amp

Potential difference = 8 Volts

Find:

Resistance in circuit

Computation:

In an electrical system, resistance is a stopper of a material to electric current.

Resistance in circuit = Potential difference / Flow of current in circuit

Resistance in circuit = 8 / 15

Resistance in circuit = 0.53 ohm (Approx.)

A flare is launched from a boat. The height, , in meters, of the flare above the water is approximately modelled by the function
Tpy6a [65]

Answer:

10 seconds

Explanation:

If the height is modeled by the function h(t)=-15t^{2} +150t, then the seconds it takes to reach the water (when the height equals 0) is modeled by the following.

0=-15t^{2} +150t\\0=-15t*(t-10)\\\\t=0\\t=10

Black_prince [1.1K]

Answer :

Label A - nucleus.

Label B- electron cloud.

Explanation :

An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.

The electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

In the picture, label A shows the nucleus.

Electrons has the ability to revolve around the nucleus in a fixed circular orbit. Electron cloud represents the spreading of the electrons energy.

In the picture, label B shows the electron cloud.

Hence, the label A - nucleus and label B- electron cloud.
