How does the air blowing between two objects bring them together? The Venturi effect is also demonstrated by the Venturi meter and states that faster air/fluid reduces pressure. Thus, when the air between the balloons moves faster than the air outside them, the outside pressure causes them to come together. How does blowing air affect […]
Which liquid is the most viscous How do you know?
Which liquid is the most viscous How do you know? Oil Which fluid is more viscous? The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of “thickness”: for example, syrup has a higher viscosity than water. Which is more […]
How can help me?
How can help me? Here’s an extremely incomplete list, just to get you thinking — I’m sure you can come up with thousands more if you think about it. Smile and be friendly. Call a charity to volunteer. Donate something you don’t use. Make a donation. Redirect gifts. Stop to help. Teach. Comfort someone in […]
What kind of acceleration occurs when an object speeds up?
What kind of acceleration occurs when an object speeds up? Consider the two data tables below. In each case, the acceleration of the object is in the positive direction. In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, […]
Why does a falcon cry?
Why does a falcon cry? Sometimes they wail because they’re annoyed but don’t feel like getting up to deal with it. Sometimes they wail because their rules of social behavior — few as they are — indicate the peregrine making the sound must wait for the other peregrine to deal with it. Do Falcons make […]
What is called surface?
What is called surface? In general, a surface is a continuous boundary dividing a three-dimensional space into two regions. Surfaces are often called by the names of the regions they enclose, but a surface is essentially two-dimensional and has an area, while the region it encloses is three-dimensional and has a volume. What is a […]

What is full form of wife? WIFE. Washing, Ironing, Feeding, Enjoyment. What being a wife means? The role of a wife is so crucial that she can either make or break a […]
How can we protect against gamma rays?
How can we protect against gamma rays? shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays. The higher the energy of the gamma ray, the thicker the shield must be. Does using mobile phone […]
What is internal energy of a system and how it changes?
What reduces friction of distance?
What reduces friction of distance? Reduction of the Friction of Distance With frequent movement from point to another through saving of time and money, interactions between the two locations tend to increase, bringing in the concept of time-space convergence. Different means of transport take different spans of time to cover a specific distance. What is […]
