The voltage across the other lamp is also 5 V.
In fact, when two resistances are connected in parallel, they are connected to the same points of the circuit. This also means that the potential difference across the two sides of the resistors is the same, therefore the voltage across the two lamps connected in parallel is 5 V for both.

Answer:
it take 687 days for Mars orbit around the sun
Explanation:
Amount of heat supplied (Q) = 24500 J
Mass (m) = 2 kg
Initial temperature (t1) = 20 ° C
Final temperature (t2) = 35 ° C
Difference in temperature (dt) = t2 - t1 = ( 35 - 20) °C = 15 ° C
Now Specific heat capacity (S) = ?
We know we have the formula;
Q = m * s * dt
24500 = 2 * s * 15
24500 = 30 S
S = 24500 / 30
S = 816.67 J / Kg ° C
The specific heat capacity is 816.67 J/kg°C.
Hope it will help :)
