Asurveyor needs to determine the height of a tree. she places a mirror on the ground and paces backwards until she sees the top of the tree reflected in the mirror. she marks where she is standing and then measures the distance from this spot to the mirror which is 1212 feet. she then measures the distance from the mirror to the base of the tree which is 9595 feet. the surveyor's height is 5858 inches from the ground to her eyes. how tall is the tree (in feet) assuming level ground from the surveyor's spot to the mirror and from the mirror to the tree?

found in the nucleus

has mass of one amu

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.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
