Answer:

<h2>e. sound. </h2>

Explanation:

  • Such type of atmosphere in which oxygen was not present or was present in little amount is known as the primitive atmosphere and such type of atmosphere was present in the initial stage of the earth formation.
  • During this period, water vapor, nitrogen, hydrogen and carbon dioxide gases were present.
  • These gases interact with the help of energy that comes from many sources such as lightning, ultraviolet radiation, electric spark and some other.
  • When these inorganic molecules react in the then the formation of organic compounds takes place that becomes the basis of the organization of the life on the earth and called an organic evolution of life.

Please answer with an explanation.
nydimaria [60]

Answer:

A, D, E

Explanation:

The force of Earth's gravitational pull is equal to the mass of the object times the acceleration due to gravity:

W = mg

The greater the mass, the greater the pull.  A truck, bicycle, and camel all have greater mass than a baseball.

Select all of the following that describes momentum, p [mark all correct answers]
Inga [223]

Answer:

c. Momentum is the product of mass and velocity

e. Momentum is a vector quantity

g. Momentum has unit of kgm/s

Explanation:

Linear momentum P

P = m .v

m =mass

v=Velocity

If mass take in kg and velocity is in m/s then momentum p will be in kg.m/s.

1. momentum is the product of velocity and mass.

2.Momentum is a vector quantity.

3.Momentum have kg.m/s unit.

So the following option are correct.

c. Momentum is the product of mass and velocity

e. Momentum is a vector quantity

g. Momentum has unit of kgm/s.

Note-

1.Joule is the unit of energy.

2.One-half the product of mass and the square of the object's speed is known as kinetic energy.

Which BEST describes the difference between speed and velocity?
kirill [66]

Answer : The correct option is, (D) Velocity includes rate of change and direction.

Explanation :

Speed : Speed is defined as the distance traveled by an object with respect to the time taken. It is a scalar quantity that means it tell us about the magnitude of an object not direction.

Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.

The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only.

Hence, the correct option is, (D) Velocity includes rate of change and direction.
