How much does a Newton of force feel like? “A Newton is about ¼ pound, the weight of a stick of margarine.” Weight is the downward force of gravity exerted on an object by the planet it is located on. What is a pound of thrust? Thrust is a force or a push. Thrust is […]

What happens when the frequency of a sound wave decreases? If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa. Therefore, if frequency increases, pitch increases and creates a higher sound and wavelengths become shorter. Why is sound […]

What are the similarities and differences between cellular respiration and fermentation? Describe the similarities and differences between cellular respiration and fermentation. Both produce ATP through the breakdown of carbon based molecules, and both allow glycolysis to continue by recycling electron acceptors. Cellular Respiration requires oxygen and produces much more ATP than fermentation. What are 3 […]

What is the brightness or dullness of a color? Intensity (also called chroma or saturation) is the brightness or dullness of a color. A color as we see it on a color wheel is at full intensity (bright). When we mix it with gray, black, or white, it becomes dull. Colors also lose intensity when […]

Can you overcharge a camera battery? Battery chargers supplied with Sony® cameras are designed to shut off when the battery reaches full charge. For this reason, InfoLithium® and lithium-ion batteries will not be overcharged. How long does a camera battery take to charge? 2 hours Can you leave a camera battery charging overnight? Leaving it […]

What happens when two celestial bodies collide? When they smash together, they create a single, larger planet, but with a cloud of debris that coalesces to form one nearby, large satellite and up to several smaller, more distant satellites. Which Lagna is good for birth? Gurū (Guru) is an excellent Graha for this Lagna and […]

Which motion is called uniform Why? Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time. What forces […]

Are J kg K and J kg C the same? Assuming you mean kJ/(kg K) and kJ/(kg C), where K stands for a unit on the Kelvin temperature scale and the C for a unit on the Celsius temperature scale, the answer is yes because the Celcius and Kelvin scale have the same unit but […]
