For example Existing rock is weathered into sediment, then compacted, cemented and finally Lithified (Lithification)
Answer:
Electrons- 95
Protons- 95
Neutrons-146
Explanation:
An atoms is made up of three fundamental particles; electrons, protons and neutrons,
Americium belongs to the f block in the periodic table. It is an actinide element.
An atom of Am-241 contains 95 protons, 95 electrons and 146 neutrons.
Answer:
Similarly, if magnet is held stationary and the coil is moved away and towards the magnet, the galvanometer shows deflection in similar manner. It is also seen that, the faster the change in the magnetic field, the greater will be the induced emf or voltage in the coil.

Answer:
0.027g
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules.
From the above, it means that 1mole of SO3 also contains 6.02x10^23 molecules.
1mole of SO3 = 32 + (16x3) = 32 + 48 = 80g
If 1 mole (80g) of SO3 contains 6.02x10^23 molecules,
Then Xg of SO3 will contain 2x10^20 molecules i.e
Xg of SO3 = (80x2x10^20)/6.02x10^23 = 0.027g
Answer:
Velocity = 4.41×10⁵ m/s
Explanation:
The force of attraction between the nucleus and the electron is equal to the centrifugal force acting on the outermost electron due to circular rotation. It can be mathematically written as:
Where,
K is the Coulomb's constant having value 9×10⁹ N. m²/C²
q is the charge on the electron or the proton which is 1.6×10⁻¹⁹ C
r is the radius of the atom
m is the mass of the electron having value 9.1×10⁻³¹ Kg
v is the velocity of the electron.
The equation can be written to calculate the velocity as:
Given that:
r = 1.3×10⁻⁹ m
So,
<u>Velocity = 4.41×10⁵ m/s</u>
