C. Should be the answer it worked for me

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.

A pitcher throws a 0.14-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just
kykrilka [37]

Answer

given,

mass of base ball = 0.14 kg

speed before it made the contact with the ball (V i) = 42 m/s

speed after batter hit the ball(V f) = - 48 m/s

a)                                            

impulse = change in momentum

             = m\times (V_f-V_i)      

             =0.14\times (-48-42)

             = -12.6 Kg m/s

Magnitude of impulse = 12.6 Kg m/s

b)                                                        

Force = \dfrac{impulse}{time}

          =  \dfrac{12.6}{0.005}

Force = 2520 N

Assume your mass is 60 kg. The acceleration due to gravity is 9.8 m/s 2 . How much work against gravity do you do when you climb
Andre45 [30]

Answer:

W=1705.2 J

Explanation:

Given that

mass ,m= 60 kg

Acceleration due to gravity ,g= 9.8 m/s²

Height ,h= 2.9 m

As we know that work done by a force given as

W = F . d

F=force

d=Displacement

W=work done by force

Now by putting the values

F= m g (Acting downward  )

d= h  (Upward)

W= m g h    ( work done against the force)

W= 60 x 9.8 x 2.9 J

W=1705.2 J

Therefore the answer will be 1705.2 J.
