The temperature of a sample of water from the faucet increases from 22.7°C to 48.9°C when 3,710J are applied through electric sh
MakcuM [25]

Answer:

33.8.

Explanation:

Hello,

In this case, since the used equation is:

Q=mCp(T_2-T_1)

Whereas the specific heat is 4.184 J/(g°C), we compute the mass as follows:

m=\frac{Q}{Cp(T_2-T_1)}

Thus, the mass turns out:

m=\frac{3,710J}{4.184\frac{J}{g\°C} (48.9-22.7)\°C}\\\\m=33.8g

And without units:

33.8.

Best regards.

What is the relationship between the strength of the magnetic field and the deflection of the galvanometer needle?
Karo-lina-s [1.5K]

Answer:

Similarly, if magnet is held stationary and the coil is moved away and towards the magnet, the galvanometer shows deflection in similar manner. It is also seen that, the faster the change in the magnetic field, the greater will be the induced emf or voltage in the coil.
