A sealed 2500 cm³ flask is full to capacity with 0.36 g of a substance. Determine the density of the substance. Guess if the substance is a gas, liquid, or solid

force tends to be low and long diustance masses are high

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
