Anya recorded the temperatures of four different smooth materials after they were placed under a heat lamp for thirty minutes. A 2-column table with 4 rows. The first column labeled Material has entries W, X, Y, Z. The second column labeled Temperature (degrees Fahrenheit) has entries 87, 99, 75, 105.
Which conclusion is best supported by the information in the chart?

Material W is less absorbent than material Z.
Material Y is the least reflective.
Material X is more reflective than material W.
Material Z is the least absorbent.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

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.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
