electric potential energy..electrons get the the kinetic energy from the voltage applied across the conductor
Answer:
2.04 s
Explanation:
v = at + v₀
(-30.0 m/s) = (-9.8 m/s²) t + (-10.0 m/s)
t = 2.04 s
Answer: 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= 16.7 kJ = 16700 J (1kJ=1000J)
m= mass of benzene = 225 g
c = specific heat capacity = 1.74 J/gK
Initial temperature of the water =
= 20.0°C = 293 k 
Final temperature of the water =
= ?
Change in temperature ,
Putting in the values, we get:


The final temperature will be 
24-15=9 m/s slower in 12 seconds. So 9/12 m/s² slower. Therefore the acceleration is -0,75 m/s²
