Periodic Table
What is the chemical symbol of Einsteinium
Es
What is the third planet from the sun
earth
what is a wave
What is a repeating disturbance that transfer energy from one pplace to another
What is period in frequency
The time it takes for one complete cycle of a wave or event.
Which of the following scenarios does not involve the force of friction?
a book falling down the table
What are the blocks
The periodic table can also be divided into blocks (s, p, d, f) based on the type of atomic orbitals that are being filled.
When a liquid is changed to a solid it is called?
What is freezing
What is amplitude
Whatt is measure of how far a particle in the medium moves away from its normal rest position
What is a Wavelength in science
he distance between two successive crests or troughs of a wave.
Milton is conducting an experiment to see how far a marble will roll when he releases it at the top of an inclined plane. Why does the marble speed up as it travels down the inclined plane?
Correct anwser: The force of gravity pulls the marble down the inclined plane.
What is the periodic law?
The periodic law states that the properties of elements are periodic functions of their atomic numbers, meaning that elements with similar properties occur at regular intervals in the periodic table.
Why does the sun apper to be the biggest star
its closest to us
What is a wavelength
what is the distance from any point of the wave to an identical point on the next wave pulse
What is Wave Speed is science
The speed at which a wave travels
Which of the following objects has the greatest gravity?
correct anwser : The sun
How do elements in the same group share similar properties?
Elements in the same group have similar electronic configurations, specifically the same number of valence electrons (electrons in the outermost shell), which affects their chemical behavior
What is the deepest part in the earth
The core
What is the frequency of a wave
what is the number of waves produced in a set amount of time
What is Hertz (Hz) in science
The standard unit of measurement for frequency, equal to one cycle per second.
What does Newton's law of universal gravitation state about the force of gravity?
correct anwser: It affects everything with mass in the universe.
Who invented the periodic table?
Dmitri Mendeleev is most often credited with creating the first widely recognized periodic table in 1869.
What is the name of our galaxay
Za milky way
How can wave speed be calulated
What is multiply wavelength by freuency
What is the frequency of the radio waves emitted by a cell phone
typically between 700 MHz and 2.7 GHz for 2G, 3G, and 4G technologies.
If two objects each have a mass of 10 kg, then the force of gravity between them _______.
Hint
Correct anwser is :is greater when they are closer together
