If an engine cannot be 100%
geniusboy [140]

Answer: Given the evidence in the explanation, I'm pretty sure it's C. It still exists, but in a different form.

Explanation: "Some part of the energy supplied is used to change the internal energy of the system. Some part is also released into the surroundings. Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings."

If you drop an object from rest, the distance it falls is given by (1/2)at2, where a is the acceleration of the object and t is
klio [65]

If,

d \:  =  \:   \frac{1}{2} a {t}^{2}

then, with 3x time t, (suppose, new distance is h)

h \:  =  \:   \frac{1}{2} a {(3t)}^{2}

=  \frac{1}{2} a9 {t}^{2}

= 9 \:  \frac{1}{2} a{t}^{2}

= 9d

Therefore, new distance h will be 9 times bigger than distance d.

answer: c

Which object has the most thermal energy?
Valentin [98]

Answer:

B

Explanation:

The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.

Thermal energy is the sum total of the average kinetic energy within the system.

It is mathematically expressed as:

    Quantity of energy  = mass   x  specific heat x  change in temperature

We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
