What is centripetal acceleration in simple words? Centripetal acceleration is defined as the property of the motion of an object, traversing a circular path. Any object that is moving in a circle and has an acceleration vector pointed towards the center of that circle is known as Centripetal acceleration. What is the formula of uniform […]

What is r in ideal gas law? The factor “R” in the ideal gas law equation is known as the “gas constant”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number. How does Boyle’s […]

How are the wavelength and frequency related? What is the relationship between frequency and wavelength? The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. What is the […]

What are the 4 components of a galaxy? From Earth, the Milky Way seems to be a heavenly mist because the stars blur together. Little do most people know, the stars are broken into four main parts. The four main parts are the disk, the nuclear bulge, the halo, and the galactic corona. What holds […]

Do we see with our eyes or brain? Our eyes do a really good job of capturing light from objects around us and transforming that into information used by our brains, but our eyes don’t actually “see” anything. That part is done by our visual cortex. Our eyes being slightly apart creates an image that […]

How do you find maximum velocity? Using Calculus If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just […]

How long does it take a star to return to the same position in the sky as it was the night before? about 24 hours Can you see the same stars in both hemispheres? Constellations such as Orion may be seen in both hemispheres, depending on your distance from the equator and the time of […]

What are the main parts of electric motor? Different Parts of an Electric Motor and Their Function A power supply – mostly DC for a simple motor. Field Magnet – could be a permanent magnet or an electromagnet. An Armature or rotor. Commutator. Brushes. Axle. What are 3 parts of an electric motor? No matter […]

How far can you kick a ball? While some weaker placekickers may have trouble kicking field goals longer than 30 yards (making field goals from beyond the 13 difficult), others may consistently make 50-yarders, making it practical to kick from beyond the 33. For most NFL kickers, the 35-yard line is typically the limit of […]

Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb? A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high. Which one is having lesser resistance a 220v 60W bulb or […]
