listen to the scientist feel the scientist be the scientist taste the scientist bam ur scientist
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
A scientist is someone who studies science.
1. A scientist must be curious about the world.2. A scientist is logical and systematic.3. A scientist is open-minded and free of bias.4. A scientist is intellectually honest.5. A scientist works hard and is persistent.6. A scientist does not jump to conclusions.7. A scientist is a creative and critical thinker.
He/she is precise. --Answer-- Assuming that the "known value" is actually correct, then this scientist is likely performing the experiment/observation wrongly (and as the saying goes if you keep doing what you've been doing, you'll keep getting what you've been getting). Wrongly here may mean that the equipment is not correct or is not correctly calibrated, or that the quantities are not correct.

When a trained scientist makes a careful observation of anything, that qualifies as a scientific observation. Scientific variables would be quantities of something,
The scientist who proposed the mole was Avagadro. It is based on his famous number - approximately 6.02 x 1023 .
Francium is not exclusively found in France, but rather, it is found throughout the Earth in extremely small quantities. Francium was discovered by a French scientist, Marguerite Perey.
Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.
quantities which are not mademade from major quantities
All other quantities which described in terms of base quantities are called base quantities.
Physical quantities can be broadly categorized as scalar or vector quantities. Scalar quantities have only magnitude, like mass or temperature, while vector quantities have both magnitude and direction, like velocity or force. Other types of physical quantities include derived quantities (obtained from combinations of base quantities) and dimensionless quantities (without units).
Basic quantities are physical quantities that are independent and cannot be defined in terms of other physical quantities, such as length, time, and mass. Derived quantities, on the other hand, are physical quantities that are defined in terms of one or more basic quantities, such as speed, acceleration, and force.
Derived quantities are quantities that you should be solving for. Ex: Volume, Mass etc Standard quantities are quantities that are specific. Ex: length, seconds, meter. Hop I helped you. :)
