2. A metal weighing 50.0 g absorbs 220.0 J of heat when its temperature increases by
1 answer:
The specific heat of the metal is
Explanation:
When a sample of a material absorbs energy, its temperature increases according to the equation
where
Q is the amount of energy supplied to the sample
m is the mass of the sample
Cs is its specific heat capacity
is the increase in temperature
In this problem,
m = 50.0 g
Q = 220.0 J
Solving for C_s, we find the specific heat capacity:

Answer:
12 units
Explanation:
This problem can be solved if we take into account the equation for a sphere
where we took that the radius is 13 units. If we take z=5 and we replace this value in the equation of the sphere we have
where we have taken x2 +y2 because if the equation of a circunference.
In this case the intersection is made when we take z=5, for this value the sphere and the plane coincides in values.
Hence, the radius is 12 units
