when acceleration is held constant and objects of different mass are observed,are mass and force directly proportional or invers
svetoff [14.1K]
Yes. When two things are directly prortional, that means that as one increases, the other increases at the same rate. So, say you have a 2kg object at an acceleration of 2m/s^2. The force would be 4N. If you have a 3kg object at an acceleration of 2m/s^2, the force would be 6N. If two things are inversely proportional, that means that as one thing increases the other decreases at the same rate. A good example of this is in a chemical reaction. If you increase the surface area of the reactants, the reaction time decreases. They are inversely proportional.

Suppose a snack bar is burned in a calorimeter and heats 2,000 g water by 20 °C. How much heat energy was released?
prohojiy [21]

Heat energy released : 167.2 kJ

<h3>Further explanation</h3>

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

m = 2000 g

c = 4.18  J/ g ° C  

∆t = 20 ° C  

\tt Q=2000\times 4.18\times 20\\\\Q=167200~J=167.2~kJ
