Chemical energy comes from the food that we eat
Which are in constant motion.
Answer:
i think the answer is "B"
Explanation:
the particles in a gas are more far apart and have more kinetic energy than liquid because they are more close together and have less kinetic energy than gas.
Answer:
a)10.28 Nm
b)9.93 Nm
Explanation:
Let g = 9.81m/s2. First we can calculate the weight of the trophy
W = mg = 1.6 * 9.81 = 15.696 N
(a) The torque is product of force and its moment arm
T = WL = 15.696 * 0.655 = 10.28 Nm
(b) Suppose his arm makes an angle of 15 degree with respect to the horizontal line. We can still calculate the arm length, or the horizontal distance from the trophy to the champion:
Again, torque is product of force and its moment arm
