Answer:

Water is a polar molecule.

Explanation:

The fundamental rule of solubility is that "like solutes would dissolve in like solvents". Both NaCl and water are polar compounds.

NaCl is an ionic compound which forms from transfer of an electron from the Cl atom and a loss of electron from Na. This leaves a separation of charge on both atoms with Na being positively charged and Cl being negatively charged. This charge separation makes NaCl a polar compound.

Water on the other hand is a polar covalent solvent. The covalent bond results from the sharing of electrons between oxygen and hydrogen atoms. Due to the more electronegative nature of Oxygen, it pulls the shared electron more closely to itself than the Hydrogen atom. This unequal sharing of the electron leaves a net positive charge on Hydrogen and a negative charge on Oxygen.

For this reason, NaCl will dissolve in water.

Choose true or false for each statement regarding a parallel plate capacitor.. The voltage of a disconnected charged capacitor i
OlgaM077 [116]

Answer:

Explanation:

The voltage of a disconnected charged capacitor increases when the plate area is decreased.

When plate area decreases , capacitance C decreases , but charge Q remains constant .

Q = C V where C is capacitance and V is voltage .

when C decreases , V increases for keeping Q constant .

So the statement is true.

The electric field is dependent on the charge density on the plates.

This statement is true .

The voltage of a connected charged capacitor remains the same when the plate area is decreased .

For a connected capacitor , V or voltage is constant which is equal to voltage of charging battery .

So the statement is true .

A hard rubber ball on a string is being used as a pendulum. When you first look at the pendulum, the ball is being held to one s
Wittaler [7]

Answer:

<h2>Total thermal energy for all air molecules is 59.54 J</h2>

Explanation:

As we know that the ball comes to rest finally so here we can say that

initial total potential energy of the ball is transferred to the air molecules

So here we have

E_{th} = mgh

E_{th} = (6.2 kg)(9.8 m/s^2)(0.98 m)

So here we have

E_{th} = 59.54 J

So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J

A boy is pulling a 150 kg crate with a force of 1150 N. If the crate experiences a frictional force of 490 N, find:
valentina_108 [34]
<h3><u>For the aceleration:</u></h3>

First, let's find the resultant, and <u>applicate 2nd law of Newton</u> using the resultant, so:

R = ma

F - Ff = ma

Data:

F = Force = 1150 N

Ff = Friction force = 490 N

m = Mass = 150 kg

a = Aceleraction = ?

Replacing according our data:

1150 N - 490 N = 150 kg * a

660 N = 150 kg * a

660 N / 150 kg = a

a = 4,4 m/s²   ← Aceleration of the object

<h3><u>For the normal force:</u></h3>

The normal force IS NOT the resultant force, the normal force's the force between the ground and the object, in another words, is the weight of the object, and for the weight:

w = mg

w = 150 kg * 10 m/s²

w = 1500 N   ← Normal force between object and ground.

Give an example of mass making a difference in the amount of gravitational energy. Tell how you know the gravitational energy is
Andreas93 [3]

Answer:

The Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.

Examples of Gravitational Energy

A raised weight.

Water that is behind a dam.

A car that is parked at the top of a hill.

A yoyo before it is released.
