The ratio of their amplitudes will be 2.41.
To find the answer, we have to know more about the simple harmonic motion. 
<h3>How to find the ratio of their amplitudes?</h3>
                         
- We have the relation between these quantities and amplitudes as,
                         
- Here, for both the oscillation, k will be same.
- Thus, the ratio of amplitude will be,
                       
Thus, we can conclude that, the ratio of their amplitudes will be 2.41.

Answer:
the bigger the mass the lesser the acceleration and vice versa 
Explanation:
this is because the acceleration is a function of the mass and this can be proven by the formula for force: F = ma
 
        
             
        
        
        
Answer:
Option A is correct.
Eddies due to enhanced mixing of fluid
Explanation:
Turbulent thermal conductivity is thermal conductivity that arises from the turbulent flow of fluids. It comes into play when a particukar fluid moves into turbulent regiom of flow where flow is no longer orderly and streamlines aren't discernable with the fluid layers all warping into one another forming vortices.
It is represented as K and is shown mathematically through the heat flux at turbulent flow
q = vCρT' = - K (∂T/∂y)
where
K = turbulent thermal conductivity
T' = the eddy temperature relative to the mean value,
C = Heat capacity the fluid
q = the rate of thermal energy transport by turbulent eddies.
The physical mechanism that cause turbulent thermal conductivity are similar to the causes of turbulent flow of fluids.
This includes sharp changes in fluid pressure and velocity of flow which is evident in eddies that come about in the enhanced mixing of fluids.

Answer:
recall that heat absorbed released is given by
Q = mc*(T2 - T1)
where
m = mass (in g)
c = specific heat capacity (in J/g-k)
T = temperature (in C or K)
*note: Q is (+) when heat is absorbed and (-) when heat is released.
substituting,
Q = (480)*(0.97)*(234 - 22)
Q = 98707 J = 98.7 kJ

The net force on the student is A) -294 N
Explanation:
Neglecting air resistance, there is only one force acting on the student: the force of gravity, which is given by

where
m is the mass of the student
g is the acceleration of gravity
In this problem, we have:
m = 30 kg is the mass of the student
 is the acceleration of gravity, where the negative sign means the direction is downward
 is the acceleration of gravity, where the negative sign means the direction is downward
Substituting, we find the force of gravity on the student:

And since this is the only force acting on the student, it is also the net force on him.
