This implies that stopping distance and impact force grow as a function of speed. The best ways to improve manoeuvrability and lessen crash severity are to drive at an appropriate pace and to slow down as soon as you spot dangers in front of you.

Keep in mind that stopping distance increases with speed; at 50 mph, it is four times longer than at 25 mph, and at 75 mph, the force of impact is nine times greater.

<h3>What is the impact of speed on kinetic energy ?</h3>

When your car expends or absorbs energy to speed up or slow down, you may feel a pull or a jolt, called impulse. Impulse increases as the energy or force increases, and increases as the duration of the force decreases. You'll feel a harder jolt if you speed up or slow down suddenly.

  • Consider: coming to a stop from 60 mph in ten seconds doesn't hurt you or your vehicle because the force of this event is spread out over a long time. But if you hit a wall and come to a stop in just half a second, you'll feel twenty times the impulse, causing severe damage.

MArishka [77]

Answer:

396.97°C

Explanation:

Charles' Law explains that at constant volume, the pressure of an ideal gas is directly proportional to its temperature (in Kelvin).

P₁ ∝ T₁

P₁ = kT₁

k = constant of proportionality

(P₁/T₁) = (P₂/T₂)

P₁ = 240.0 kPa

T₁ = Boiling point of water = 100°C = 373.15 K

P₂ = 431.0 kPa

T₂ = ?

(240/373.15) = (431/T₂)

T₂ = (431 × 373.15) ÷ 240

T₂ = 670.12 K

T₂ = 396.97°C

Hope this Helps!!!

What are constellations?
tatiyna

Answer:

Option 4

Explanation:

A constellation can be defined as that region formed by the stars in such a way that the formation by the group of stars in that area appear to seem an imaginary pattern of some mythological creature, animal, god or some inanimate object formed apparently.

Thus in accordance with the above definition a constellation is a group of stars that forms some apparent pattern in the celestial sphere.

A car has a distance between axles of 6.2 m and a center of mass located 2.2 m from the front axle. What is the
NARA [144]

Answer:

The correct option is  C

Explanation:

From the question we are told that

    The distance between axles of the car  is  d_a  =  6.2

     The position of the car's center of mass is  D  = 2.2 \ m  \ in \ front \  of  \  the \  axel

Now  we can evaluate the distance of the center of mass to the rear axle as follows

        k  =  d_a  -  D

substituting values

      k  =  6.2 -  2.2

      k  = 4 \ m

assuming the car is   at equilibrium,  taking moment about the center of mass

          W_{front \  axle} *  D  -  W_{rear \  axle} *  k  = 0

=>        W_{front \  axle} *  D     =  W_{rear \  axle} *  k

=>       \frac{W_{front \  axle}}{W_{rear \  axle} }       =    \frac{k}{D}

substituting values

             \frac{W_{front \  axle}}{W_{rear \  axle} }       =    \frac{4}{2.2}

           \frac{W_{front \  axle}}{W_{rear \  axle} }       =    1.81       Note [W_{front \  axle} is the front axle weight  and  

                                                      W_{rear \  axle} is the rear axle weight  ]

does a Neon atom emits specific frequencies of light that correspond to decreases in energy of its electrons.
zlopas [31]

Answer:

Yes, the frequency of light emitted is a property of the difference between the levels of energy of its electrons.

Explanation:

Neon atom is a noble gas which glows when its electrons de-excites after absorbing energy.

Niels Bohr postulated that the energy level in all atoms are quantized, thus electrons do not exist in-between two levels.  When electrons in the Neon atom are excited, this increase in energy causes them to jump to a higher energy levels. On de-excitation, the electrons drops to their initial level releasing the absorbed energy in the form of a photon.

The photon emitted has a frequency that is directly proportional to the energy change in the electron.
