Potential and kinetic energy along with an external force
They literally gave you the answer but okay.
Correct answer should be: B. 490 Meters
1/2 x 9.8 x 10^2
Plug them in a calculator and you get <u>490 meters. </u>
<u>G </u>= Gravity which is 9.8 m/s^2
<u>T</u>= Time
Answer:
40sec
Explanation:
Data
Work = 440 J
Power= 11watt
time = ?
Power = work done/time
===> time = work done/power
= 440/11
= 40sec
technically usually the warmer object/substances particles move master which causes friction among the particles plus the kinetic energy being converted to thermal energy, so i would say the hand.
