Answer: Option c

Explanation:

Nebula is a birthplace or stellar nursery where stars take birth. Gases condense to form a nebula. Then these gases start to collapse under their own gravity. This heats up the matter which is condensing which gives rise to a protostar. After the formation of protostar, if the mass is sufficient and temperature is high enough, nuclear fusion reaction kicks in at the core and starts to release energy and enters the main sequence.

Hence, the correct order of process leading up to the formation of main sequence star is: option c

  1. Gases condense to form a nebula
  2. gravity causes the nebula to collapse and spin
  3. a protostar forms
  4. nuclear fusion occurs.

__ modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas power

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.

In order for an object to have kinetic energy it must have a mass and a ?
almond37 [142]

Answer:

Velocity

Explanation:

  • The mechanical energy of the body is defined as the sum of the potential energy and kinetic energy.

                                   E = P.E + K.E

  • The potential energy of a body is due to the height from the surface of the earth.

                                  P.E = mgh

  • The kinetic energy of the is possessed by the body due to the virtue of its motion,

                                  K.E = ½ mv²

  • If there is no velocity associated with the body, there is no K.E in the body.
