According to einstein, nothing in the universe can move faster than which approximate speed?

The speed of light, because light is made of photon's, and photon's have infinite mass which allows them to move so fast.

nothing can move faster than the speed of light

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

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.
