Answer:
Mass, m = 27g
Explanation:
<u>Given the following data;</u>
Initial Temperature, T1 = 25°C
Final temperature, T2 = 50°C
Quantity of heat = 2825J
Specific heat capacity of water = 4.184
Heat capacity is given by the formula;
Where,
Making mass, m the subject of formula, we have;
Change in temperature, dt = T2 - T1
Change in temperature, dt = 50-25 = 25°C
Substituting into the equation, we have;
Mass, m = 27g
Therefore, the mass of water that can be added is 27 grams.
Well we can just use F=ma. The force is 10N, the mass is 50 kg, solve for a. Well since we kg and N, no conversion is necessary. So just plugging in the numbers, we get
10N = 50 kg · a
A newton is just
The s^2 and 50 kg you multiply
The kg's cancel and 10/50 is 1/5
So the acceleration is 1/5 m/s^2
