What happens if I put a balloon in the freezer? What would happen if you put a balloon in the freezer? As the air cools it compresses and therefore exerts less pressure on the balloon. If cold enough your balloon will be visibly deflated. If you then bring back to room temperature it will return […]
What is the velocity of star?
What is the velocity of star? In the Milky Way, stars usually have velocities on the order of 100 km/s, whereas hypervelocity stars typically have velocities on the order of 1000 km/s. Most of these fast-moving stars are thought to be produced near the center of the Milky Way, where there is a larger population […]
Does carrying a heavy bag build muscle?
Does carrying a heavy bag build muscle? When you lift your backpack to place onto your back, you use your shoulder muscles (i.e. deltoids). Throughout the hike you will do this a number of times so make sure that you also have enough strength. Like the abdominal muscles, they stabilise the body and prevent fatigue […]
Which tissue gains flexibility faster?
Which tissue gains flexibility faster? Muscle fascia is the third connective tissue that affects flexibility, and by far the most important. Fascia makes up as much as 30 percent of a muscle’s total mass, and, according to studies cited in Science of Flexibility, it accounts for approximately 41 percent of a muscle’s total resistance to […]
Which describes the first law of thermodynamics?
Which describes the first law of thermodynamics? The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. “So, it’s a restatement of conservation of energy.” What is the second […]
What speed do radio waves travel in a vacuum?
What speed do radio waves travel in a vacuum? Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. How far can […]
Why is there a difference between Celsius and Fahrenheit?
Why is there a difference between Celsius and Fahrenheit? Celsius scale, or centigrade scale, is a temperature scale that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. Fahrenheit scale is a temperature scale that is based on the freezing point of water at 32°F and […]
What happens if the temperature is higher than the dew point?
What happens if the temperature is higher than the dew point? Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew […]
Is germanium a good conductor of electricity?
Is germanium a good conductor of electricity? Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. They are not conductors in the metallic sense of the word, but are semiconductors. Which is better conductor silicon or germanium? Germanium is a […]
Would the target rise up higher lower or the same if the bullet passed through the target rather than embedding in it?
Would the target rise up higher lower or the same if the bullet passed through the target rather than embedding in it? Would the target rise up higher, lower, or the same if the bullet passed through the target rather than embedding in it? Need Help? Is energy conserved in explosions? Yes, it is. Do […]
