What is the major divide or ridgeline that separate Virginia's watersheds?

1 answer:

6 0

In Virginia, the continental divide separates the New River from the Roanoake and James River. East of the continental divide, the rivers flow east or south toward the Atlantic Ocean. West of the continental divide, the rivers flow north or west toward the Gulf of Mexico by way of the Ohio and the Mississippi Rivers.

In a roller coaster, both the kinetic and potential energy in the car decreases at

Lemur [1.5K]

We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at each successive hill because of the force of gravity which converts potential energy into kinetic energy.

<h3>What are potential and kinetic energy?</h3>

Potential energy is referred to as positional energy.
This means that the object in question gains energy based on its position relative to others.
Kinetic energy is the energy of movement.
Gravity causes the roller coaster to fall, losing potential energy.
This causes it to gain all of the potential energy as kinetic energy.
Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

Adiabatic process is a process in which _ is constant (a) temperature (b)volume (c)pressure (d) heat

fomenos

Answer: Adiabatic process is a process in which heat is constant

Explanation:

The processes in which temperature remains constant is called isothermal process.

The process in which Volume remains constant is called isochoric process.

The process in which pressure remains constant is called isobaric process.

The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

Thus option d) heat is correct

What mass of dinitrogen monoxide, N2O, contains the same number of molecules as 3.00 g of trichlorofluoromethane, CCl3F?

erica [24]

Answer:

0.9612 g

Explanation:

First we calculate how many moles are there in 3.00 g of CCl₃F, using its molar mass:

3.00 g CCl₃F ÷ 137.37 g/mol = 0.0218 mol CCl₃F

Now, we need to calculate how many grams of N₂O would have that same number of molecules, or in other words, the same amount of moles.

Thus we calculate how many grams would 0.0218 moles of N₂O weigh, using the molar mass of N₂O :

0.0218 mol N₂O * 44.013 g/mol = 0.9612 g N₂O
