Which planet has the slowest orbital velocity? If Pluto had maintained its planet status, it would have the slowest orbital speed at just 10,438 miles per hour. Instead, Neptune again wins with an orbital speed of 12,148 miles per hour. Compared to Earth’s 66,621 miles per hour, Neptune is practically sluggish. What season is Earth’s […]
What happens if I put a balloon in the freezer?
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 […]
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 […]
Does a bullet touch the barrel?
Does a bullet touch the barrel? Bullets touch the inside of the gun’s barrel during normal operation. There’s rifling inside the barrel that’s supposed to impart spin on the bullet. So the barrel rubs grooves in the bullet (this is how CSI can match a bullet to a gun) but the softer bullet does little […]
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 […]
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 […]
At what distance does gravity end?
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 […]
