Consider a force of 750 n (roughly the weight of an adult human). over what area (in cm2) would this force need to be applied in order achieve a solid pressure (stress) of 25 mpa (the pressure required to rupture average human skin)? [recall : 1 mpa = 106 pa , and 1 pa = 1 n/m2]

are there options? cause you ain’t. real specific

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.
