Answer:
6.77 minutes
Explanation:
172 degree - 78 degree = (185 degree - 78 degree)e−2 k
=> 94 = 107
e−2 k => 94 ÷ 107
k => ln (94÷107) / 2
147 - 78 = (185 - 78)e ^[ln (94÷107) / 2]
=> 69 = 107 e^ [ln (94÷107) / 2]
e^[ln (94÷107) / 2] =69 ÷ 107
=> t = [ln (69 ÷ 107)] ÷ [ln (94÷107) / 2]
t=> -0.4387 ÷ -0.0648
t => 6.77 minutes.
Therefore, the final answer to the question is 6.77 minutes.

Answer: 5.29 seconds
Explanation:
if the speed is 24 meters per second than it would take you 5.29 seconds or 127meters/24m/s to get 5.29s
I think that it’s the first one
Explanation:
a) ΔU = -500 J + 800 J = 300 J
b) ΔU = mCΔT
300 J = (0.3 kg) (1000 J/kg/°C) ΔT
ΔT = 1 °C
