1. friction between water molecules
2. the wave spreads out onto a larger and larger area, so per unit area, the energy of the wave goes down
Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)
Pseudoscience because it involves beliefs not facts
Answer:
98 N
Explanation:
The weight of an object is given by:
where
m is the mass of the object
is the acceleration due to gravity
In this problem, the mass of the lemur is m=10 kg, so its weight is
