Answer:
40% of the energy release by the peanut is 3500 calories
Explanation:
One calorie is defined as the amount of energy required to increase the temperature of one gram of water for one degree Celsius (or one Kelvin)
Equation for energy gain by water is
Q = mcΔT
where, m is the mass of the object
c is the specific heat capacity
ΔT is the change in temperature
c = 1.0 cal/g?°C.
m = 50 g
ΔT = 50°C - 22°C
= 28°C
Q = (50)× (1)× (28)
= 1400calories
The peanut contain 1400calories of energy .
amount that 40% of energy is released to water ,
so,
Q = 1400 calories / 0.4
= 3500 calories
Therefore, 40% of the energy release by the peanut is 3500 calories

The correct answer is - T (True).
The goal and purpose of the environmental engineers is to minimize the impact of the land that is being developed on the environment itself. This is due to the efforts being made that the environment is kept as it is as much as possible, because any damage on it has bad consequences for everyone and everything. So this type of engineers are trying to find the perfect balance between the development of the land for human usage and also to manage to preserve as much as possible the environment and to minimize any damage on it.
