If we assume the density of water= 1000 gm/lit.
so Volume = Mass / Density
Vol. = 524.24/1000
Vloume = 0.52424 liters
The answer is; D
Diffraction of light occurs when the light encounters an obstruction that is smaller than its wavelength. The water droplets in the clouds can be very small and be closer in size to the wavelength of light. When sunlight encounters a cloud droplet, light waves are altered and interact with one another in a similar manner as the water waves causing fringes of light around clouds.
Answer:
Alpha, beta, and gamma particles
Explanation:
A shield of aluminium can effectively block off any form of radiation be it alpha, beta or gamma particles.
Radiations are products of nuclear reactions. These radiations produced are quite harmful and injurious to life.
A thick and appropriate material must be used to block off these radiations so as to properly interact with them in an advantageous way.
A shield of aluminium, a block of lead and any material with a high thickness and density is appropriate for neutralizing these forms of radiation.
18 g of silicon-32 will be present in 800 years.
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and it's given by
where,
quantity of the substance remaining
the initial quantity of the substance
time elapsed
the half-life of the substance
From the given information we know:
The initial quantity of silicon-32 is 40 g.
The time elapsed is 800 years.
The half-life of silicone-32 is 710 years.
So, using the calculation above, we can determine how much silicon-32 is left.
Therefore,18 g of silicon-32 will be present in 800 years.

Answer:
atomic orbital
Explanation:
Atoms are made of three sub-atomic particles, electron, proton and neutron.
Protons and neutrons are present in the core of the atom in a very small zone called nucleus. Nucleus is positively charged.
Electrons are present around the nucleus. Electrons present outside the nucleus are also termed as electron cloud. Region outside the nucleus where probability of finding an electron is maximum is termed as atomic orbital. Four basic types of orbitals are present around the nucleus which are
s-orbital
p-orbital
d-orbital
f-orbital
Electrons present in same orbitals have same energy. Therefore, term is atomic orbital.
