Answer:
Explanation:
When an amount of energy Q is supplied to a sample of substance of mass m, the temperature of the substance increases by according to the equation
where
is the specific heat capacity of the substance
In this problem, we have:
m = 55.0 g is the mass of the sample of silver
is the amount of energy supplied to the sample
is the change in temperature of the sample
Solving the equation for , we find the specific heat capacity of silver:
Answer:
The acceleration of each mass is the same, and approximately equal to
Explanation:
Notice that the mass of the whole system is: 30 kg + 40 kg = 70 kg
If we use a net force of 100 N on the combined system, we can find the acceleration imparted to the masses via Newton's second law:
