Answer:
2.943 J
Explanation:
Data:
acceleration due to gravity, g = 9.81 m/s²
mass of sand = 0.5 kg
distance = 0.6
Thermal energy = the energy possessed by the falling sand
The force of sand = ma
= 
However, the energy is given as the force multiplied by the distance, so
E =fd
Therefore, the thermal energy is 2.943 joules
Answer:
V=IR
since the circuit is parallel both resistor have same voltage and different current value according to OHMs law.
total resistance in parallel=
1/R=1/R1+1/R2+...+1/Rn
since we have two resistor in parallel
Rt=R1R2/R1+R2
2*4/2+4=4/3 ohms
I=V/R
12/4/3=36/4=9Amp
OR
I=12/2=6amp
I=12/4=3amp
total current
I=6+3
9amp
The temperature of the water getting colder would cause the liquid in the thermometer to drop due to less heat being transferred from the water to the liquid, so the liquid molecules are closer than when they have high energy.
