Which skier will have a greater potential energy? Justify your answer.

pochemuha

Answer: Skier 1 will have more potential energy because he is higher than skier 2

Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.

P.E= $m\times g\times h$

m= mass of the body

g= acceleration due to gravity

h= height of body

Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.

The bonds that link many water molecules together to form a water drop are _____ bonds.

Gelneren [198K]

The bonds found between water molecules are called:

Hydrogen bonds

which contribute to water having a high number of Van Der Waals forces.

Explanation:

A hydrogen bond is an electromagnetic attraction within polar molecules in which hydrogen is joined to a larger atom, such as oxygen or nitrogen. This is not a dividing of electrons, as in a covalent bond. Preferably, this is an attraction among the positive and negative poles of charged atoms.
