Back before Astronomy was well-understood, people used the "Apparent" motion of the Sun across the sky as the measure of the length of the day. Now that we know better, we measure the length of a day as one complete rotation of the Earth. This is known as a sidereal day (sigh-deer-ee-al) which is approximately 23 hours, 56 minutes, 4.09 seconds, corresponding to the time it takes for the Earth to complete one rotation with reference to the vernal equinox.
What else can I help you with?
What are the units used to measure bmr?
kcal/day
A measure of the average energy of random motion of particles of matter?
Temperature is the average energy of random motion of particles of matter :). Hope that helps
Which term is defined as a measure of the energy of motion of particles in a substance?
Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.
How an object can be measure by its change in position from one area to another?
motion
What is an example of a frame of reference for the motion of a snowboarder?
A tree can be used for a frame of reference for the motion of a snowboarder.
What is the electric hammer use to measure motion?
An electric hammer typically used in construction or demolition work is not designed to measure motion. However, devices such as accelerometers or motion sensors are commonly used to measure motion, providing precise data on an object's movement, acceleration, and vibration.
How the hell do you measure motion?
You can measure distance traveled, energy used or work done.
What is used to measure the energy of motion of particles in a substance?
Joules
What is the sunshine recorder used to measure?
The sunshine recorder is used to measure sunlight used in a day.
Which is used to measure force a newton or a kilogram?
A newton is used to measure force, while a kilogram is used to measure mass. Force is the product of mass and acceleration, according to Newton's second law of motion.
For what purpose would one use a goniometer?
A goniometer is a device used to measure the range of motion in a joint. Medical professionals use them to determine the range of motion in human joints, while they can also be used to measure angles in inanimate objects.
What is meant by sensor?
A sensor is a device that is used to measure something and record it. It can measure heat, sound, light, frequency, or motion and respond to it.
Does the goniometer measure a joint of minimum range of motion?
Yes, a goniometer can measure joints with both small and large ranges of motion. It is a tool commonly used in physical therapy and medicine to assess and quantify the range of motion in various joints of the body.
When you measure an object's resistance to motion you must measure what?
Inertia is an objects resistance to change in motion. Frictional forces resist motion.
What is momentumm?
A quantity used to measure the motion of a body, equal to the product of the body's mass and its velocity.
What imaginary line can be used to measure the motion of celestial object?
The celestial equator is an imaginary line in the sky that is used to measure the motion of celestial objects. It is a projection of Earth's equator into space and helps astronomers locate objects in the sky based on their declination.
What Is A measure of the average amount of motion of molecules?
Temperature is a measure of the average amount of motion of molecules in a substance. It is related to the kinetic energy of the molecules and can be used to predict the direction of heat transfer between two objects.
