What is example of isolated system? A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. Thus a thermos does not allow energy for transfer. Is universe isolated system? A system is isolated when there is no energy exchange with the surroundings. […]
What happens to resistance if current is doubled?
What happens to resistance if current is doubled? The current is directly proportional to the voltage and inversely proportional to the resistance. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value. What would the current in Problem 3 become if the resistance were doubled? Answer. if […]
What are the 4 main types of solar energy?
What are the 4 main types of solar energy? The most common types of solar energy Photovoltaic systems. One of the most common ways to use solar power is to use photovoltaic systems or as they are also known solar cell systems, which produce electricity directly from sunlight. Solar water heating systems. Solar power plants. […]
How important are the parts to its whole?
How important are the parts to its whole? Study of the whole contributes perspective and meaning to study, and helps to tie things together. It helps to see where they have made progress. Study of the parts isolates areas of weakness, develops skills and saves time in practice, thus being more efficient. What is a […]
What are the 3 ways to transfer energy?
What are the 3 ways to transfer energy? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer of […]
Can you see image of your face in a plane mirror in a dark room Why?
Can radius of curvature zero?
When two bodies are charged the total charge before and after charging remains the same?
When two bodies are charged the total charge before and after charging remains the same? Conservation of charge The law of conservation of charges states that the total charge in an isolated system remains the same. Which forces can be either repulsive or attractive? But there is a major difference between the two laws. The […]
Does the brain send it messages to move?
Does the brain send it messages to move? The brain is the body’s control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around. What happens in the brain when we move? Muscles move on commands […]
What are the critical aspects of designing a good experiment?
What are the critical aspects of designing a good experiment? 1.1 Study Design: basic concepts The set of explanatory factors. The set of response variables. The set of treatments. The set of experimental units. The method of randomization and blocking. Sample size and number of replications. The outcome measurements on the experimental units – the […]
