Answer:
Frequent shallow earthquakes
Explanation:
Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.
During an earthquake when the earth shakes it produces a super shear earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity.
The mechanisms of shearing depend on the pressure and temperature of the rock and on the rate of shear which the rock is subjected to.
Answer:
d) 1/32 microgram
Explanation:
First half life is the time at which the concentration of the reactant reduced to half.
Second half reaction is the time at which the remaining concentration reduced to half or the initial concentration reduced to 1/4.
Third half life is the time at which the remaining concentration reduced to half or the initial concentration reduced to 1/8.
Forth half life is the time at which the remaining concentration reduced to half or the initial concentration reduced to 1/16.
Fifth half life is the time at which the remaining concentration reduced to half or the initial concentration reduced to 1/32.
The initial mass of the sample = 1 microgram
After 5 half-lives, the mass should reduce to 1/32 of the original.
So the concentration left = 1/32 of 1 microgram = 1/32 microgram

Answer:
The mass is
Explanation:
From the question we are told that
The mass of the stars are
The orbital speed of each star is
The orbital period is
The centripetal force acting on these stars is mathematically represented as
The gravitational force acting on these stars is mathematically represented as
So
=>
=>
=>
=>
The distance traveled by each sun in one cycle is mathematically represented as
Now this can also be represented as
Therefore
=>
=>
So
=>
=>
