Answer : The specific heat capacity of the alloy
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of alloy = ?
= specific heat of water =
= mass of alloy = 21.6 g
= mass of water = 50.0 g
= final temperature of system =
= initial temperature of alloy =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat capacity of the alloy
Answer:
Explanation:
The electric field produced by a single point charge is given by:
where
k is the Coulomb's constant
q is the charge
r is the distance from the charge
In this problem, we have
E = 1.0 N/C (magnitude of the electric field)
r = 1.0 m (distance from the charge)
Solving the equation for q, we find the charge:
