Answer:
b
Explanation:
by using formula
a=(v-u)/t
where a= acceleration
v = initial velocity = 10 m/s
u= final velocity =50 m/s
t = time taken = 2s
The correct answer is 5819.04 J
The energy (q) required to elevate an object of mass (m) and specific heat capacity (c) by a temperature (T) is given by q = mcΔT.
Here, m is 72 g, c is 0.449 J/Kg °C, ΔT = 260 - 80 = 180 °C
Now, putting the values we get,
q = 72 × 0.449 × 180
q = 5819.04 J of energy is absorbed by the skillet.
