What are the energy conversion devices? Devices Dynamo. Mechanical energy into electrical energy. Electric motor. Electrical energy into mechanical energy. Microphone. Sound energy into electrical energy. Loud speaker. Electrical energy into sound energy. Electric Bulb. Electrical energy into light and heat energy. Solar cell. Candle. Sitar. Which of the following is an example of a […]

Does voltage stay the same in series? 2. In a series circuit the current is the same at any particular point on the circuit. 3. The voltage in a series circuit, however, does not remain constant. Why does voltage decrease in a series circuit? In series circuits, the resistor with the greatest resistance has the […]

What are the phases of a star? Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to […]

Why can hydrogen only have two valence electrons? Because hydrogen only has one electron surrounding its nucleus, its valence shell is the first energy shell, which only needs two electrons to be full. Hydrogen tends to form covalent bonds because a single covalent bond will fill its shell. How many valence electrons are present in […]

What is an example of a stationary object? For example, a heavy bag resting on a bed pushes on the bed because of its downward weight force and the bed pushes back up on the bag with a balancing force as it is squashed under the load. What is the force of a stationary object? […]

What happens when tryptophan is present? When tryptophan is present in the cell, two tryptophan molecules bind to the trp repressor, which changes shape to bind to the trp operator. Binding of the tryptophan–repressor complex at the operator physically prevents the RNA polymerase from binding and transcribing the downstream genes. What time should I take […]

What do water ice and steam have in common? When water freezes, its molecules move farther apart, making ice less dense than water. This means that ice will be lighter than the same volume of water, and so ice will float in water. As some of the water vapor cools, we see it as a […]

Which state of matter has the most kinetic energy? gaseous Do liquids have kinetic energy? Liquids have more kinetic energy than solids. If you add heat energy to a liquid, the particles will move faster around each other as their kinetic energy increases. Some of these particles will have enough kinetic energy to break their […]

What does it mean if a charge is in equilibrium? Equilibrium condition states that the magnitude of force F1 and magnitude of force F2 should be equal to one another. How does the electric field due to an infinite line of charge vary with the distance from the line? We have found that the electric […]

What is a mesocyclone Brainly? A rapidly rotating air mass within a thunderstorm that often gives rise to a tornado. What is one of the conditions necessary for a thunderstorm to develop? There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving. What are […]
