Answer:

Driving a motor vehicle often requires <u>LESS or STANDARD</u> reaction time.

Explanation:

While driving on road it requires less or standard reaction time because while driving the motor vehicle on road the situation to make instant decision may occur at any time. While driving on road there may happen that the person driving in front of you may apply brakes instantly.

Due to this you have to instantly react for that situation and apply brakes in your car also.

If our reaction time is not standard or less then in that case the our car will travel closer to the car front of us and then if we even apply hard push on the brakes then also the car will not stop and it will skid towards the another car and it may occur collision with it.

So it always requires less or standard reaction time

LUCKY_DIMON [66]

By Newtons Third law this is an action reaction pair of force
So the momentum is the same
30*20=50*x where x is velocity
x= 12m/s
direction is towards left since they act in opposite directions

The diagram shows a ball resting at the top of a hill.

WARRIOR [948]

Answer:

a) The potential energy in the system is greatest at X.

Explanation:

Let be X the point where a ball rests at the top of a hill. By applying the Principle of Energy Conservation, the total energy in the physical system remains constant and gravitational potential energy at the top of the hill is equal to the sum of kinetic energy, a lower gravitational energy and dissipated work due to nonconservative forces (friction, dragging).

$U_{grav, X} = U_{grav, Y} + K_{Y} + \Delta W_{X \rightarrow Y} = U_{grav,Z}+\Delta W_{X \rightarrow Z}$

Conclusions are showed as follows:

a) The potential energy in the system is greatest at X.

b) The kinetic energy is the lowest at X and Z.

c) Total energy remains constant as the ball moves from X to Y.

Hence, the correct answer is A.

Hybrid

<u>Hybrid</u> modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas powered.

The driving wheels of hybrid vehicles receive power from their drivetrains.
A hybrid car has numerous sources of propulsion.
There are numerous hybrid configurations.
A hybrid vehicle might, for instance, get its energy from burning gasoline while alternating between an electric motor and a combustion engine.
Although they have primarily been employed for rail locomotives, electrical vehicles have a long history of integrating internal combustion and electrical transmission, like in a diesel-electric power-train.
Because the electric drive transmission directly substitutes the mechanical gearbox rather than serving as an additional source of motive power, a diesel-electric powertrain does not meet the definition of a hybrid.
Only the electric/ICE hybrid car type was readily accessible on the market as of 2017.
One type used parallel operation to power both motors at the same time.
Another ran in series, using one source to supply power solely and the other to supply electricity.
Either source may act as the main driving force, with the other source serving to strengthen the main.
