Will your brain let you stub your toe? It’s scientifically proven that your brain won’t let you stub your own toe. Can stubbing your toe break it? Stubbing a toe can even cause breaks, sprains, broken nails, and infections. The pain of a stubbed toe usually subsides after a few minutes. In some cases, however, […]

What are examples of perfectly inelastic collisions? Another common example of a perfectly inelastic collision is known as the “ballistic pendulum,” where you suspend an object such as a wooden block from a rope to be a target. What makes a collision perfectly inelastic? An inelastic collision is a collision in which there is a […]

Will Ball move by itself? Answer: No! Explanation: Because In the first law of motion , an object will not change its motion unless a force acts on it. Is no motion a balanced force? The two forces were equal in size and opposite in direction, so they cancelled out each other, and no motion […]

How do I become more likable? How To Be The Most Likable Person In The Room Compliment others genuinely and often. Ask more questions about others than you make statements about yourself. Assume everyone has something to teach you. Ask deeper questions. Ask for advice. If you’re in a negative emotional place, remove yourself. Stop […]

Are planes built like birds? Birds have streamlined shapes so that when they are in flight the air can flow on their surface smoothly. Engineers used the shape of the birds as inspiration to model the planes (4). Most airplanes have a streamlined shape so that they do not face air resistance when they are […]

Why does a balloon float? Balloons float because they are filled with helium! Balloons can be filled with different types of gas. Other gasses are very light and will float away from the surface. One of these gasses is called helium. Would a balloon of hydrogen float away? In order to get a floating balloon […]

How current is generated? Electric current can be generated by moving a metal wire through a magnetic field. It is also different than static electricity, which is the accumulation of charges on a surface. Electric generators rotate a coil of wires through a magnetic field. How do I calculate current? Ohms Law and Power To […]

What is evaporation process? Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. What is effect of evaporation? The water level will decrease as it is exposed […]

How long is a 20 Hz wavelength? 56.5 ft What is the relationship between speed frequency and wavelength? The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. […]

What does 3 B mean in algebra? So 3(a+b) means to multiply 3 by (a+b) What is B in algebra? In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept […]
