Answer:
when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium
Explanation:
The concept of center of gravity is equivalent to the concept of center of mass, in this place all external forces applied can be considered.
When we analyze the balance of a body that is the torque it is the one that defines the balance
τ = F xd
If the torque tends to restore the body to the initial position the balance is stable, but if the torque has to increase the body's rotation the balance is unstable
. When the body tends to rotate the torque with respect to the pivot point at the base it decreases because the distance from the center of gravity to the end of the base decreases in value, but it has to return it to the initial position, the balance is stable. The critical point of this process is when the center of gravity is at the limit of the body base area in this case the torque is zero; If the body rotates a little more the center of gravity is outside the base, the torque changes sign and has to increase the turn, going to an unstable balance.
In summary, when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium.
Answer:
Heat capacity, Q = 2090 Joules.
Explanation:
Given the following data;
Mass = 100 grams
Specific heat capacity = 4.18 J/g°C.
Temperature = 5°C
To find the quantity of heat required;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
t represents the temperature of an object.
Substituting into the formula, we have;
Heat capacity, Q = 2090 Joules.
Answer:
The patient could be going through paralysis, which is when the motor neurons are severed which stops electrical signals from passing into the muscles. It can be caused by severe trauma to the body or psychological stress.

Answer:
I am pretty sure is either C or D hope this helps
Answer:
The value is 
Explanation:
From the question we are told that
The diameter of the nucleus is 
The charge of the proton that makes up the nucleus is 
The energy to be impacted is 
Generally the radius of the nucleus is mathematically represented as
=> 
=> 
Generally from the law energy conservation we have that
i.e
Here
Here 
is the initial kinetic energy which is mathematically represented as
Here 
is the initial potential energy of the proton and the value is 0 J given that the proton is moving
Also 
is mathematically represented as
Here
is the final potential energy which is mathematically represented as
Here 
is the charge on the proton with a value of 
So
=> 
So
=> 
Here m is the mass of the moving proton with value 
So
=> 
=>
