The salesperson tells Ben that Motorcycle A produces {288}\ \text{ J} 288 J
of kinetic energy and {312}\ \text{ J}
312 J
of heat and sound energy when {600}\ \text{ J}
600 J
of chemical potential energy is supplied to it.
Motorcycle B produces {400}\ \text{ J}
400 J
of kinetic energy and {200}\ \text{ J}
200 J
of heat and sound energy for the same amount of chemical potential energy.

Help Ben decide which motorcycle to buy through calculating the energy efficiency of each of them.

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the answer is simply just 6n add the two together as they have an n

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
