Is that your answer ☺️☺️☺️
To solve this problem, it is necessary to apply the concepts related to Work according to the Force and distance, as well as the concepts related to energy lost-or gained-by heat. Mathematically the energy corresponding to heat is given as:

Where,
m = mass
= Specific heat
= Change in Temperature
At the same time the Work made by the Force and the distance is given as:

As the force is applied at an angle of 30 degrees, the efficient component would be given by the vertical then the work / energy would be determined as:



Now this energy is used to heat the aluminum. We can find the change at the temperature as follow:



Therefore the correct answer is B.
Urbanization can cause a lot of problems for nature such as pollution, global warming, and depletion of wildlife such as plants and animals.
Answer:
Explanation:
maximum energy of capacitor
E = 1/2 C V ²
C is capacitance of capacitor and V is potential difference
given V = 88 V
E = 2002 x 10⁻⁶ J
Putting the values
2002 x 10⁻⁶ = 1/2 x C x 88²
C = .517 x 10⁻⁶ F .
In the second case
Energy E = 125 x 10⁻⁶ J .
C = .517 x 10⁻⁶
V = ?
E = 1/2 C V ²
125 x 10⁻⁶ = 1/2 x .517 x 10⁻⁶ x V²
V² = 483.55
V = 21.98 V .
