Why is my body so buoyant? A human submerged in water weighs less (and is less ‘dense’) than the water itself, because the lungs are full of air like a balloon, and like a balloon, the air in lungs lifts you to the surface naturally. If its less dense than water, then it will float. […]
What is the average kinetic energy of an atom?
Which of the following is a surface phenomenon?
Which of the following is a surface phenomenon? When the temperature rises, then the process of evaporation occurs, as a result of which the molecules are easily disintegrated at the surface. It is due to this, the process of evaporation is commonly considered as a surface phenomenon. Why is melting a surface phenomenon? The kinetic […]
What is an example of maintaining homeostasis?
What is an example of maintaining homeostasis? The maintenance of healthy blood pressure is an example of homeostasis. If blood pressure is too high, the heart should slow down; if it is too low, the heart should speed up. More than half of a human’s body weight percentage is water, and maintaining the correct balance […]
Is Viking 1 still active?
Is Viking 1 still active? The Viking mission was planned to continue for 90 days after landing. Each orbiter and lander operated far beyond its design lifetime. Viking Orbiter 1 continued for four years and 1,489 orbits of Mars, concluding its mission August 7, 1980, while Viking Orbiter 2 functioned until July 25, 1978. What […]
How fast would a pyroclastic flow kill you?
How fast would a pyroclastic flow kill you? Pyroclastic flows are flows composed of gas and volcanic material—prior research has shown that they can flow downhill away from an eruption at speeds of up to 450 mph—and temperatures are as hot as 1000 degrees C. When a person is overcome by such a flow, the […]
Why do we call it spring?
Why do we call it spring? Spring. Unsurprisingly, the spring season gets its name from the verb “spring.” It’s a nod to the flowers and plants springing up, springing open, and bursting into blossom. Who named the Four Seasons? The Four Seasons, Italian Le quattro stagioni, group of four violin concerti by Italian composer Antonio […]
What are the object that can float in the air?
What are the object that can float in the air? THINGS THAT FLOAT IN AIR Paper. Kites. Balloons. Dust. Birds. Flies. Aeroplane, etc. What things are done by moving air? Background information: Air can move things – think of leaves or sand blowing on a windy day. It can speed things up or slow things […]
How much force is required for an object that is moving at a constant velocity?
What is an example of static friction?
What is an example of static friction? Cheese resting on an incline because static friction holds it in place. Another example of static friction comes when objects are moving. When you are walking, static friction pushes in the direction of you are trying to move (see Figure 2 below). What is static friction and its […]
