Answer:

There are many things that convinced scientists of the existence of atoms,  and it has been accepted for at least 100 years now, examples are the macroscopic behaviour of gases, the light emitted by hydrogen lamps, and more recently it has become possible to see individual atoms with the best microscopes!

Explanation:

There are many reasons why people thought that our material world was composed of atoms. One of the most striking reasons why scientists came to believe in atomic theory was how it could explain phenomena like the behaviour of gases, by assuming that gases were composed of a great number of individual particles moving randomly, scientists like Maxwell and Boltzmann developed a theory that could explain the macroscopic behaviour of gases, this theory is called the Kinetic Theory of Gases.

More convincing maybe is how Quantum mechanics can predict phenomena like the atomic emission spectrum of Hydrogen and many molecules and atoms. That the spectra of different elements can be explained by assuming they are made of atoms and using quantum mechanics to predict the frequency at which these atoms will emit or absorb light is a very convincing argument! The Spectrum of hydrogen can be seen with an hydrogen lamp and a prism to separate the different wavelengths.

Moreover, modern electron microscopes can indeed detect single atoms! That means that one can quite literally see single atoms.

Most of the technological development of humanity for the last century wouldn't have been possible without atomic theory, as it underpin our understanding of the physical world.

A ball thrown with 50N of force accelerates at 25 m/s2.  What is the mass of the ball?
MrRissso [65]
F=ma
Force is 50N. Acceleration is 25 m/s^2.
50N=m*25 m/s^2
Divide both sides by 25.
mass=2 kg

As the temperature of water drops, it continues to give off thermal energy until it freezes. This is an example of.
jeka57 [31]

Answer:

The answer should be C

Explanation:

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.

A 42.0-kg parachutist is moving straight downward with a speed of 3.85 m/s. (a) If the parachutist comes to rest with constant a
RideAnS [48]

Answer:

-414.96 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-3.85^2}{2\times 0.75}\\\Rightarrow a=-9.88\ m/s^2

F=ma\\\Rightarrow F=42\times -9.88\\\Rightarrow F=-414.96\ N

The force the ground exerts on the parachutist is -414.96 N

If the distance is shorter than 0.75 m then the acceleration will increase causing the force to increase

A object is located 16.0 cm in front of a converging lens whose focal length is 12.0 cm. A diverging lers ength of 10.0 cm is lo
Anuta_ua [19.1K]

Answer:

first lens v = 48 cm

second lens v = -15.6 cm

magnification =  1.67

final image is virtual

and final image is upright

Explanation:

given data

distance = 16 cm

focal length f1 = 12 cm

focal length f2 = 10.0 cm

to find out

location of the final image and magnification and Type of image

solution

we apply here lens formula that is

1/f = 1/v + 1/u     .....................1

put here all value and find v  for 1st lens

1/12 = 1/v + 1/16

v = 48 cm

and  find v  for 2nd lens

here u = 20- 48 = -28

- 1/10 = 1/v - 1/28

v = -15.6 cm

and

magnification = first lens (v/u) ×  second lens ( v/u)

magnification =  (-15.6/-28) ×  ( 48/16)

magnification =  1.67

so here final image is virtual

and final image is upright
