Answer:
134.75935 seconds
Explanation:
m = Amount of water = 240 mL
c = Specific heat of water = 4.2 J/mL °C
= Change in temperature = 
t = Time taken
P = Power = 1100 W
E = Pt
Efficiency = 51 %
So, Energy = 0.51Pt
As energy is conserved
Q = 0

The it takes to raise the temperature is 134.75935 seconds
The change in kinetic energy of the car is equivalent to the change in its potential energy. Thus:
K.E = P.E
1/2 x mΔv² = mgΔh
h = (8.2² - 5²) / 2(9.81)
h = 2.15 meters
The answer should be I because it’s the o my one that makes sense it’s the same metal just in smaller pieces
Answer:
it is called Group of heterogeneous mixture
Explanation:
Because heterogeneous means uneven or with different compositions
So not evenly mixed will be heterogeneous mixture
