Answer:
500J (joules)
Explanation:
since heat is is the product of mass, change in temperature, and specific heat, the solution can be found from the equation q = mcΔt, heat is 50 * .5 * 20 = 500J
The best way (in my opinion) is to put it in a table or spreadsheet.

Explanation:
<span>Answer
is: </span>the objects mechanical energy is 52,92 J.<span>
m(object) = 0,3 kg.
h(object) = 18 m.
g = 9,8 m/s².
E(object) = m·g·h.
E(object) = 0,3 kg · 9,8 m/s² · 18 m.
E(object) = 52,92 N·m = 52,92 J..
g - the acceleration of free fall.
mg - weight of the object.</span>
