Answer:
- The positive charge in an atom is concentrated in one location.
Explanation:
In Rutherford's experiment when alpha particles are projected towards the gold foil then he observed that major proportion of the alpha particles are moved out undeviating.
This shows that alpha particles which are positively charged are not repelled by other positive charge of nucleus as it is concentrated at small part of atom
because very few alpha particles are reflected back at 180 degree so he concluded that nucleus charge is concentrated at very small space
and that part is termed as nucleus.
so correct answer is
- The positive charge in an atom is concentrated in one location.
a. 2
b. 1
c. 0
d. 2
Answer:
1) An unstable nucleus
c. emits energy when it decays
2)The charge on gamma ray is
c. 0
3) what particle is emitted in alpha radiation?
c. helium nucleus
4) The least penetrating form of radiation is
c. Alpha radiation
5) What is the change in atomic number when an atom emits a BETA particle?
D. increases by 1

a lithosphere
a biosphere
a cryosphere
the answer is bioshere
Answer:
A biosphere
Explanation:
Biosphere refers to the zone of life on a planet. It includes all living elements of a planet. It is also known as Eco-sphere and includes the interaction of all living being with their surrounding.
Of all the planets and exo-planets, Earth is the planet known to have life and thus biosphere.
Whereas atmosphere, lithosphere and cryosphere can be found on other planets as well.
Atmosphere: Layer of air and gases surrounding a planet or any celestial object. (Except Mercury, all the planets of solar system have atmosphere)
Lithosphere: it refers to the rigid outer part of the planet which includes crust and mantle. (All the rocky planets have lithosphere)
Cryosphere: portion of the planets where water is in ice form. (Many exoplanets have been discovered having cryosphere)
Answer:because of small amount of oxygen
Explanation:
If you get higher by the atmosphere the air will start to decrease
Answer:
Curiosity
Explanation:
The word that is more in line with this definition is curiosity, a good scientist is characterized by being extremely curious about the phenomena that surround him, a very clear example of this was Einstein, who said "I have no special talent. I am only passionately curious. "
This question comes along with four answer choices:
a) the thermal energy moving from the coffee to her tongue
b) the thermal energy moving from her tongue to the coffee
c) her coffee
d) her tongue
Answer: a) the thermal energy moving from the coffee to her tongue.
Explanation:
Heat, heat energy and thermal energy are terms to refer the same thing.
Heat is the kinetic energy of the molecules or particles in a substance wich is transferred from hot substances to cool substances.
In the example, the coffe is hot and Ixchelt's tongue is cool, so the heat is the thermal energy transferred from the hot coffe to Ixtchel's tongue.
The thermal energy (heat) always flows from the hot to the cold, never the other way around.
