Answer:
Q = 114895 J
Explanation:
To find the thermal energy gained by the ice you use the following formula:
m: mass of the ice = 0.250kg
T2: final temperature = 22°C
T1: initial temperature = -8.0°C
Hf: heat of fusion of water = 3.34*10^5 J/kg
c: specific heat of water = 4186 J/kg
By replacing the values of the parameters you have:
where you have considered that ice melts completely
Answer:
I think its C and D
Explanation:Force is like a energy that moves stuff. :)
S=d/t this is because speed is just the measurement of time and distance
Answer:
The current increases when the circuit is closed.
Explanation:
As the complete question is not given, the complete question is attached herewith.
From the data the resistors are connected in parallel and the value of Battery EMF is increased thus as the resistance is decreased and the EMF of the battery is increased, thus the current will increase when the switch is closed.
