3. Given a bronze wire of length 2.5 m and cross sectional area 6.5 x 10^-7 m2. What is the elongation of the wire if it is stretched under a force of 10^3 N? Given: Young modulus
of bronze is 2.0 x 10^11 N/m2.​

the assestment will probley apele with cause and effect

0.19 m/s and 0.45 m/s

v=ir = 3x15 =45 v

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.
