Mass/volume cause you divide to get density
Answer:
a stone has Kinetic energy when it hits the ground.
Explanation:
electric and radiant energy has nothing to do with the stone hitting the ground. kinetic energy has to deal with gravity.
Answer:
Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.
Answer:
The correct option is the A
Explanation:
Like oxygen is more electronegative than hydrogen, it attracts electrons stronger than hydrogen. Therefore the two covalent bonds are polar.
The option b is incorrect because if oxygen and hydrogen had similar electronegativities, they would form no-polar bonds.
The option c is incorrect because oxygen is more electronegative than hydrogen (you can check that in a periodic table).
The options d and e are incorrect because the molecular size or hydrophilic don't influence the type bond.
