In most cases, people didn't have access to sophisticated measuring devices, so they relied on body parts, which were easy to carry around and offered somewhat consistent results. For example, the width of a man's thumb is about an inch ("thumb" and "inch" are interchangeable in many ...
Is a kWh a unit of power or a unit of work? How to convert mm to cm with a formula What is the proper unit for gravitational potential energy? How is power measured in a combustion engine? Is a calorie a unit of energy? How to convert miles to kilometers with a formula ...
What is the mass and weight of 1420 lb of snowmobile and 412 kg of a heat pump? How much does a 115 kg barbell weigh in Newtons? What is the mass in kg of a box weighing 28.0 N? A suitcase measures 1.0 m x 0.5 m x 0.2 m and has a mass of 10 kg. What is its weigh...
In computing, farads as capacitance units of measurement measure the ability of an electrical capacitor to store an electrical charge. This is much like how an ohm is used to measure units of amperage or a joule is used to measure units of energy produced by the force of one newton, which...
For example, given the sun's mass of 1.989 × 10³⁰ kg, its Schwarzschild radius occurs at about 1.86 miles (3 kilometers) from its central point, that's compared to the sun's radius of around 432,450 miles (696,000 kms). Earth's Schwarzschild radius is even closer to its cent...
What is kg/m Is it density? The kilogram per cubic metre (symbol: kg·m−3, or kg/m3) is an SI derived unit of density, definedby mass in kilograms divided by volume in cubic metres. How many cm is 1 kg? The answer is: The change of 1 kg - kilo ( kilogram ) unit of con...
In the middle of the spacecraft, near its center of gravity, are four 100-pound (45 kg) reaction wheels used to reorient the observatory. Based upon Sir Isaac Newton’s Third Law of Motion — for every action there is an equal and opposite reaction — turning a reaction wheel in one ...
In contrast, the lower mantle is under tremendous pressure and therefore has a lower viscosity than the upper mantle. The metallic nickel–iron outer core is liquid because of the high temperature. However, the intense pressure, which increases towards the inner core, dramatically changes the melti...
What is gravity in feet per second?Gravity:Gravitational force is the attraction of two masses. When one of the masses is immensely larger than the other, the force between them is large and causes the smaller mass to accelerate. This is what we call the acceleration due to gravity. Each ...
The kilogram (also kilogramme) is the base unit of mass in the International System of Units (SI), the metric system, having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo in everyday speech. Newton The...
