The heat capacity is given by the expression:
When the
is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in
, we can then determine the specific heat "C" by simply remplazing in the expression.
To solve this problem we will apply the concepts related to the moment of inertia and Torque, the latter both its translational and rotational expression.
According to the information given the moment of inertia of the body would be
Replacing we have
Now the translational torque would be the product between the force applied (Its own Weight) and the distance (Its center of mass at the middle)
Now the rotational torque is defined as the product between the moment of inertia and the angular acceleration, then,
Replacing,
Therefore the angular acceleration is
Answer:
0.86 m
Explanation:
q₁ = magnitude of positive charge = 5 x 10⁻⁶ C
q₂ = magnitude of negative charge = 3 x 10⁻⁶ C
r = distance between the two charges = 0.250 m
d = distance of the location of third charge from negative charge
q = magnitude of charge on third charge
Using equilibrium of electric force on third charge
d = 0.86 m
