A projectile fired from a cannon with an angle of 30deg, the projectile clears a 10m wall which is located 100 m away from the cannon.

the higher the current the higher the mag field around it the higher the influence on the compass

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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.
