What apparatus is used to measure joules?
Depends on the manifestation of the energy. For kinetic energy, it can be derived from the amount of work done, and other factors. For chemical energy, it can be computed, or various experimental methods can be used, such as a calorimeter.
How many volts of energy can a supernova produce?
Energy output is not measured in volts. A volt is the difference in potential between two points. Energy output is measured in joules (the work done to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N. · m)). The total energy output of supernovas is not consistent between examples. The Crab Nebula, for instance, produced ten to the 44th power joules.This is as much energy our sun is expected to put out in its entire lifetime, about 10 billion years.
What are the 3 dimensions of a cubic-meter container?
That is 1 metre x 1 metre x 1 metre, and it is commonly called a "stere"
Why is the unit for energy called joules?
Work is determined by multiplying force by the distance moved in the direction of that force. The resulting unit is the newton metre. But, in SI, compound units are often given a special name and, in this case, the newton metre is called a joule -in honour of an English physicist, James Prescott Joule.
Does the stiffness of the bow in a bow and arrow affect the potential energy of the bow?
Yes because the energy stored in the bow (ideally) is the force times the distance. 1 metre drawn against a force of 100 pounds (445 Newtons) gives a potential energy of 445 Joules. That energy converted totally into kinetic energy in a half-pound arrow could propel it at 44 metres/sec, or 98 mph.
How many dekatherm in a cubic meter?
The answer depends on one cubic metre of what substance. A cubic metre of dry sand, for example, has a thermal energy of very nearly zero dekatherms.
Are planets energy receivers?
Yes, they receive energy from the Sun. The power received from the Sun by a planet is 1.36 kilowatts per square metre divided by the square of the planet's distance from the Sun in astronomical units. Neptune receives only about 1½ watts per square metre.
Can energy to be both potential energy and kinetic energy?
Yes but not both at the same time. All energy is conserved, therefore energy before equals energy after. For example jumping from a ten metre diving board you have gravitational potential energy as you are fulling gravitational potential energy is converted to kinetic energy.
What is a linier metre as compared to metre?
The only reason a metre would need to be called a "linear metre" is to distinguish it between a "square metre" (1 metre in length timesed by one metre in width) and a "cubic metre" (1 metre in length timesed by one metre in width timesed by one metre in height).Therefore, one linear metre is the same measurement as one metre.
How do you convert metre to square metre?
A metre cannot be converted to a square metre. A metre is a length and a square meter is an area.
What is the volume of metre long metre wide and metre high?
It is 1 cubic metre.
What is one fourth of a metre is what percent of a metre?
1/4 of a metre is 25% of a metre
How do you mesure electrical energy for domestic purpose?
Electrical energy is measured by a kilowatt-hour metre. All electrical consumers have one, usually where the supply cable enters the property.
What does a newton meter measure?
A Newton metre measures torque. It can also be used to measure energy, in which case, it is the equivalent of a joule.
Are sun and wind both sources of energy?
They are both sources of energy. The Sun's energy comes in the form of heat and light via electromagnetic waves at about 1.3 kilowatts per square metre. Wind energy is kinetic energy that is used to drive sails or wind turbines.
What are lineal meters?
A linear (lineal) metre is the same thing as a metre. I think it's a dumbed down term for a metre so people won't get confused with metre, square metre and cubic metre.
Why is the temperature of Neptune very cold?
Because it is 30 times as far from the sun as earth is. This means that an equatorial square metre on Neptune gets 1/900 of the solar radiation (and so energy) compared to an equatorial square metre on earth.
