Does static electricity mean that the charges never move? explain

Answers

Answer 1

Answer: No it would be completely wrong to assume that static electricity means that the charges never move. Any kind of electricity always involves the movement of electrons. In reality, static electricity is caused by friction or by rubbing electrons from the surfaces of other materials. So the electrons did not get there by current and thus it is called static electricity.

An unknown substance has a mass of 0.125 kg and an initial temperature of 90.5°C. The substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water initially at 29.5°C. The mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32.0°C. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance.

Which of the following is an example of an object that could have a net force greater than zero acting on it?A. a glass resting on a table
B. a ball rolling down a ramp
C. a ladder leaning against a wall
D. a toy car moving east at a constant velocity

Answers

Net force is basically the force an object has when changing direction, so the answer would be D.

An object could have a net force greater than zero acting on it is a toy car moving east at a constant velocity because of the direction it moves.

You are worried that a solid substance has dissolved in a beaker of water in a lab. What would be a way to separate the substance from the water?A. Boil the water away, leaving the substance behind in the beaker.
B. Pass the solution through a filter to let the dissolved substance separate.
C. Use a magnet to draw out the solid substance from the water.
D. Pour the liquid along a rough surface that would catch the solid particles but not the water.

Answers

Boiling the water away, leaving the substance behind in the beaker is the way to separate the mixture. The correct option is A.

What is a mixture?

A mixture is basically a substances comprised of two or many distinct chemical substances which are indeed not linked covalently.

A mixture is the usually physicalcombination of two or more substances that retain their identities as well as are mixed in the way to form solutions, suspensions, along with colloids.

When two or more distinct substances are physically combined, a mixture is formed that can be distinguished back into its original substances.

When two or more substances combine to form a new substance that cannot be separated back into its original substances, a chemical reaction occurs.

The mixture can be separated by boiling the water away and leaving the substance in the beaker.

Thus, the correct option is A.
