Explanation:
Amount of heat supplied (Q) = 24500 J
Mass (m) = 2 kg
Initial temperature (t1) = 20 ° C
Final temperature (t2) = 35 ° C
Difference in temperature (dt) = t2 - t1 = ( 35 - 20) °C = 15 ° C
Now Specific heat capacity (S) = ?
We know we have the formula;
Q = m * s * dt
24500 = 2 * s * 15
24500 = 30 S
S = 24500 / 30
S = 816.67 J / Kg ° C
The specific heat capacity is 816.67 J/kg°C.
Hope it will help :)
Answer: -3.8 degrees celcius
Explanation:
Global and annual mean temperatures from 1860 to 1996, as measured in situ at weather/climate stations.
M = 4kg
F =8N
a..?
F =m.a
8 = 4.a
a = 2m/s^2
This mechanism is called primary production . Other organisms called heterotrophs take in autotrophs as food to carry out functions necessary for their life.
