Answer:
77.5°C
Explanation:
Data obtained from the question include the following:
Mass (M) = 100g
Heat (Q) = 1x10^3 J
Change of temperature (ΔT) =..?
Note: The specific heat capacity (C) of gold = 0.129 J/g°C
With the above information obtained from the question, we can obtain the change in temperature as follow:
Q = MCΔT
Divide both side by MC
ΔT = Q/MC
ΔT = 1x10^3 / (100 x 0.129)
ΔT = 77.5°C
Therefore, the change in temperature is 77.5°C

Answer:
3270m
Explanation:
1 minute= 109m
so
30 minutes= 109 × 30 = 3270m
(whatever you do on one side you have to do to the other)
hope this helps :)
