What is stop motion animation Why was it important to animation?
What is stop motion animation Why was it important to animation? Why was this important to animation? Stop motion animation is an animation technique to make a physically manipulated object appear to move on its own. The objects/puppets are made by the artist, and each time they are moved, the artist photographs them instead of […]

How do you explain observations?
How do you explain observations? Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. What […]
What is an example of a terrestrial food chain?
What is an example of a terrestrial food chain? Well, for starters, a food chain is a series of interconnected feeding relationships among different species in an ecosystem. With this in mind a common terrestrial food chain example is grass-grasshopper-snake-hawk. Primary producers, which include plants, are at the bottom (or base) of the food web. […]
Can a TV show make you depressed?
Can a TV show make you depressed? A study in Preventative Science Reports found elevated depression levels when people spent more time on computers and watching TV. In fact, those who spent more than four hours each day staring at a screen were about twice as likely to have depression. Is binge watching bad for […]
Why does altitude make you lose weight?
Why does altitude make you lose weight? What causes weight loss at high altitudes? Many studies have looked at climbers at high altitudes and, expectedly, increased energy expenditure due to increased physical activity can contribute to some of their weight loss. Does altitude affect sleep? Sleep Disturbances Trouble sleeping is quite common at high altitude. […]
How do you calculate maximum power transfer?
How do you calculate maximum power transfer? Condition for Maximum Power Transfer Therefore, the condition for maximum power dissipation across the load is RL=RTh. That means, if the value of load resistance is equal to the value of source resistance i.e., Thevenin’s resistance, then the power dissipated across the load will be of maximum value. […]
What is the effect of temperature on the viscosity of liquids?
What is the effect of temperature on the viscosity of liquids? The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. What is viscosity how it varies with temperature? In general, the viscosity of […]
