Trequires1200 kg of coal to produce the energy needed to make 1.0 kg of aluminum metal. if a single soda can requires approximately 15 g of al, what mass of coal would be needed to produce a 6-pack of cans?

The mass of coal is 108 kg.

Explanation:

Given that,

Energy of coal = 1200 kg

Mass of aluminum = 1.0 kg

Energy required for single soda can = 15 g of Al

Energy required for 6 pack of cans =

We need to calculate the mass of coal

Using formula of mass

Put the value into the formula

Put the value into the formula

Hence, The mass of coal is 108 kg.

the answer would be 32*f

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.
