Beta emission is occurring in the given nuclear reaction.
Answer: Option B
<u>Explanation:</u>
In this equation, the reactant is the Thorium atom, which is reduced to palladium. As the atomic number get decreased by one, so an electron will be emitted. This process of emission of electrons by radiation or decaying the reactant nuclei to form a new product nuclei is termed as beta emission.
So, the electrons are generally termed as beta particles while the positrons are termed as positive beta particles. So this is a kind of radioactive reactions where the reactant changes to new element by releasing an electron and thus there is a change in the atomic number of the product by one.
Explanation:
The given data is as follows.
mass = 0.20 kg
displacement = 2.6 cm
Kinetic energy = 1.4 J
Spring potential energy = 2.2 J
Now, we will calculate the total energy present present as follows.
Total energy = Kinetic energy + spring potential energy
= 1.4 J + 2.2 J
= 3.6 Joules
As maximum kinetic energy of the object will be equal to the total energy.
So, K.E = Total energy
= 3.6 J
Also, we know that
K.E = 
or, v = 
= 
= 
= 6 m/s
thus, we can conclude that maximum speed of the mass during its oscillation is 6 m/s.
Answer:
The vibrations will put the particles into suspension reducing the frictional forces between them.
Explanation:
The downslope movement of surface material under the direct influence of gravity is called "Mass Wasting." Mass wasting plays a vital role in transferring the products of weathering from their original sites to lower-lying places where the agents of erosion can pick them up for transporting a longer distance.
There are 2 main types of mass wasting;
1. rapid mass movements
2. slow mass movements.
Shearing of soil grains from S-waves rounds jagged corners reducing frictional resistance. Also, Shaking from the seismic waves increases the water content of the material.
Mass movements are part of a continuum of erosional processes between weathering and stream transport. Mass movement causes regolith and rock to move down-slope where sooner or later the loose particles will be picked up by another transporting agent and eventually moved to a site of deposition such as an ocean basin or lake bed.
Mass movement processes are occurring continuously on all slopes; some act very slowly, others occur very suddenly, often with disastrous.
How earthquake cause mass movement
1. Earthquake causes vibrations and this will put the particles into suspension reducing the frictional forces between them.
2. It also cause the shaking from the seismic waves increases the water content of the material.
