Newton's 2nd law?

An object of mass m undergoes an acceleration a when acted upon by a force F. In the form of an equation, this reads F = ma

1

The man from New Zealand who Discovered atomic nucleus

Ernest Rutherford

1

Who was the first to use a terminology 'quantum'?

Max Planck

3

Who discovered that light is a wave?

James Clark Maxwell

4

Explain F = G x m1 x m2 / r^2

What is F, G, m1, m2 and r^2

F - force
G - Gravity
M1 and M2 - mass of the two objects
r^2 - square distance

Force equals gravity times the two masses divided by square distance (between the two masses)

5

What does 'quanta' mean?

Packets or Discrete

5

Where did Max Plank work?

Paris

12

James Clerk Maxwell from Scotland

Showed that the Light is an electromagnetic wave

14

Who came up with a new approach to quantum theory?
The job of Nature is to make predictions for quantities that can be compared to experimental result.

German physicist Werner Heisenberg

15

When was radioactivity discovered?

1896

16

Who described once a self important official as being 'like Euclidean point: he has position without magnitude"

Ernest Rutherford

17

What nationality is Niels Bohr

Danish

18

Newtons 1st law?

Every object remains in a state of rest or uniform motion in a straight line unless is is acted upon by a force

19

What happens when electrons jump orbits?

They emit light

20

When did Isaac Newton published his lows?

5 July 1687

21

Newton's equation of gravity?

F = G m1xm2/r^2

22

Jumping electrons emitting light

Niels Bohr

23

Who published the first quantum theory of atomic structure and when?

Niels Bohr in 1913

24

Newton's 3rd law?

To every action there is an equal and opposite reaction
