Milligram and kilograms are two common units of mass. one milligram is 10⁻⁶ kg. Hence, 76 Kg is 76 × 10⁶ mg.
What is mass?Mass of a substance is the measure of its total amount. The standard unit of mass is grams (g). Mass is an extensive property which is dependant on the amount of particles in it.
There are several units of expressing mass, like gram, milligram (mg), kilogram (kg), nanogram (ng), etc. They can be interchanged between each other by certain relations.
Milligram unit is generally used to express the doses of drugs and small quantities.
One milligram = 10⁻⁶ kilograms.
Hence, 1 kg = 10⁶ mg
Therefore, 76 Kg is 76 × 10⁶ mg.

In any experiment the accuracy of the data and experiment can be improved. What are some things that can be done to improve data and experiment accuracy?
Choose all that apply:
Conduct more trials.
Add more controls.
Add less controls.
Add more variables
Add less variables
Choose a different person to do the experiment.
Answer:
Conduct more trials.
Add less variables.
Choose a different person
Explanation:
More trials gives plenty of data to be examined.
Less variables makes for less confusion, and less things to keep track of.
Different person ensures that the experiment is not being done by one single person who could be messing up the data
Answer:
conduct more trials, less variables, more controls
Explanation:
more trials make it so if something goes wrong you have other data, less variables because you should only test one variable at a time, more controls helps set your base line for the experiment

How are
viscosity, the size and shape of particles
and internal friction related
Answer:
With the addition of heat, liquid particles move faster, decreasing viscosity. However, the addition of heat to gas particles causes them to collide with each other more often, increasing the viscosity. ... Particles with larger size and shape collide more often, increasing internal friction.

Food contains what form of energy?
-Nuclear
-Gravitational
-Radiant
-Chemical
Answer:
Chemical energies
Explanation:
We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy - this is one way of making electricity, see Electricity for more information.

What type of weathering will occur more rapidly in an area with extremely cold winters and hot summers?
Answer:
mechanical weathering through the process of ice wedging
Explanation:
Answer:
In cold climates, the freezing and thawing that occurs causes rapid mechanical weathering through the process of ice wedging. In warmer climates, chemical weathering is more rapid because the chemical reactions that dissolve rocks and minerals are accelerated by warm temperatures.

The density of pure solid copper is 8.94 g/mL. What volume does 34 g of copper occupy?
hey there ! :
Density = 8.94 g/mL
mass = 34 g
Volume = ??
Therefore:
D = m / V
8.94 = 34 / V
V = 34 / 8.94
V = 3.803 mL

Answer: revolve:
365 days
causes seasons
rotate:
causes day and night
spins
go around
the one that has one earth goes in rotate the other one goes in revolve
Answer:
causes day and night goes in rotate365 days goes in revolvespins goes in rotate24 hours goes in revolvecauses seasons goes in rotationgo around goes in revolveExplanation:
Earth is closer to the sun and revolves around it in about 365 days. Sentences: Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time a planet takes to revolve around the sun is called a year there for 365 days would be revolve.
It takes the earth abut 24 hours, or one day, to make one complete rotation. At the same time, the earth is moving around the sun. This is called a revolution there for 24 hours is revolve.
the spinning of the earth is called rotation therefore its rotate.
Earth rotates on its axis; this causes us to experience day and night. But Earth's axis is tilted 23.5 degrees (the angle is measured between Earth's equatorial plane and the plane in which it orbits our Sun) therefore causes day and night is rotate.
Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists therefore causes of seasons is rotate.
Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution therefore earth spins goes in revolve.

two samples of water, 10 grams and 50 grams are in sperate cups which of the following properties is different for the two boiling point, color density or volumn
Answer:
volume
Explanation:
The volume of the two samples of water will be different because volume is the amount of space occupied by a body. It is dependent on the amount of materials it contains.
The 50g sample will have a higher volume compared to the 10g sample. The boiling point and density are intensive properties and do not depend on the amount of matter present. Since both samples are from the same source, they will have the same color.Answer:

All of the following undergo hybridization except
A. C
B. Si
C. Mg
D. B
Answer:
C: Mg
Explanation:
Hybridization of atomic orbitals is a fundamental concept introduced by Pauling that describes the mixing of orbitals at an atom which adds a definite direction to the Lewis - shared electron pair or electron chemical - bond concept.
Carbon(C) can hybridized on sp, sp2 and sp3 simply because it's valence shell gives room for it.
For silicon(si), when forming covalent bonds with other atoms, it's 3s and 3p orbitals are mixed with each other to form new hybrid orbitals.
Magnesium in itself doesn't hybridized except in magnesium hydrides.
Boron orbitals(B): when boron forms bonds with three other atoms like borazine, they are hybridized to either the sp2 or hybridized to the sp3 which occurs when boron forms bonds with four atoms just as is in metal borohydrides.
