Which of these is a consequence of speeding less wear on brakes? When a car is speeding, the ability of the car to make sharp bends is decreased because the time required to negotiate the bend is reduced. When at high speed, the brakes can easily fail due to high wear and tear on the […]
How high can a balloon go?
How high can a balloon go? Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop. What is the common unbalanced force acting on an object in […]
What is the formula for aluminum oxide and why?
What is the formula for aluminum oxide and why? Aluminum oxide has a chemical formula Al2O3. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications. How do you activate aluminum oxide? The preparation method comprises the following steps: (1) dissolving and hydrolyzing solid sodium tetrachloroaluminate by using an ethanol […]
What is the most famous line of longitude?
What is the most famous line of longitude? Prime Meridian What is International Date Line Why is it not a straight line? The Dateline Is Not Straight The dateline runs from the North Pole to the South Pole and marks the divide between the Western and Eastern Hemisphere. It is not straight but zigzags to […]
What can be visible or infrared?
What can be visible or infrared? Visible light has a wavelength that ranges from 380 nm – 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm – 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with […]
Which functions are continuous and differentiable everywhere?
Which functions are continuous and differentiable everywhere? In mathematics, the Weierstrass function is an example of a real-valued function that is continuous everywhere but differentiable nowhere. It is an example of a fractal curve. Is every continuous function is integrable? What we get from this is that every continuous function on a closed interval is […]
How do I know if my tub is cast iron?
Is the voltage the same for capacitors in series?
Is the voltage the same for capacitors in series? When capacitors are connected in series and a voltage is applied across this connection, the voltages across each capacitor are generally not equal, but depend on the capacitance values. Why a capacitor should be connected in parallel not series? Capacitors are devices used to store electrical […]
How is energy transferred in a bicycle?
How is energy transferred in a bicycle? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that […]
