It’s biotic because it’s a living thing
Abiotic would be like a rock non living things
Answer:Biotic

Explanation:
Answer : The mass of ice melted can be, 3.98 grams.
Explanation :
First we have to calculate the moles of ice.

where,
Q = energy absorbed = 27.2 kJ
= enthalpy of fusion of ice = 6.01 kJ/mol
n = moles = ?
Now put all the given values in the above expression, we get:


Now we have to calculate the mass of ice.

Molar mass of ice = 18.02 g/mol

Thus, the mass of ice melted can be, 3.98 grams.
To develop the problem we will start by finding the energy taken by each cycle through the efficiency of the motor and the exhausted energy. Later the work will be found for the conservation of energy in which this is equivalent to the difference between the two calculated energy values. Finally the estimated time will be calculated with the work and the power given,








PART A)
Work done by the heat engine in each cycle = W



According to the value given we have that,


Power is defined as the variation of energy as a function of time therefore,




Therefore the interval for each cycle is 0.75s
Answer:
c. Slowly slide down the incline and then stop.
Explanation:
The first block slides down a rough incline since friction forces are strong enough to countereffect the effects of gravity forces and friction force is directly proportional to mass. Hence, a greater mass means higher friction forces. Net acceleration is zero.
The smaller block has a greater mass, it slides down the incline and decelerates before stopping. Net acceleration is negative.
The correct answer is c.
