Calculated the pressure exerted when a force of 100N is applied on a area of 25m2

P = 4[Pa]

Explanation:

Pressure is defined as the relationship between Force over area. So we can use the following equation.

where:

P = pressure [Pa] (units of Pascals)

F = force = 100 [N]

A = area = 25 [m²]

Now replacing:

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.
