A book with a mass of 5 kg is pushed off a table with the velocity of 2 m/s. What is its momentum? A. 7 kg-m/s
B. 3 kg-m/s
C. 15 kg-m/s
D. 10 kg-m/s

Answers

Answer 1
Answer:

The momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s is option D. 10 kg-m/s.

What is momentum?

  • Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
  • It is the vector quantity. It has both magnitude and direction.
  • In the International System of Units, the unit of measurement of momentum is Kg*m/s.

What is the momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s?

  • Formula of momentum = p = mv

Here,

        p = momentum

        m = mass

         v = velocity

  • Here the given mass is 5 and velocity is 2. then,

        p = mv

           =5×2

           =10 Kg*m/s

Hence, the momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s is option D. 10 kg-m/s.

Two or more waves combining to produce a wave with a smaller displacement is called _____. A. constructive diffraction

B. constructive interference

C. destructive interference

D. destructive diffraction

Answers

Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .

What is the definition of destructive interference?

Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:

\rm d sin \theta = n \lambda

Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .

Hence, option C is correct.

What is the difference between a permanent magnet and a temporary magnet

Answers

A permanent magnet does not loose its magnetism easily. It can only be lost by permanent destruction say by fire. Example of this is magnetism from a bar magnet. This magnetism is not induced by say electric current.

A temporary magnet looses its magnetism easily. The magnetism is gained or loosed for the action of carrying out a particular task. This magnetism can be achieved by the gain or loss by passing of electric current over say an iron core.    
Pernament magnet is one that retains its magnetic properties for a long period of time. Temporary megnet only maintains its magnetism while in a magnetic field produced by permanent magnet or electric current.

What happens on the side of earth opposite the moon?

Answers


On the side of Earth opposite the Moon, people over there don't see
the Moon, for about 12 hours and 20 minutes.  Then they see it again. 
And they tend to have a high tide somewhere around the middle of that
period of time.  I mean if they live on the coast, of course.

Didn't you really mean to ask about the side of the Moon opposite the Earth ? ?
That story is a lot more interesting.
The sun and moon gets the angle of a seabed coming up the coast land and the high ocean currents and winds all affect the height of the tides.
