Radiation is the only one that works across the vacuum of space
Those dots represent the valence electrons of the element. The only elements with 6 valence electrons are oxygen, sulfur, selenium, and..... so on. SO the answer to your question is B, tellurium(Te).
The procedure that makes stars sparkle is the same one that we have outfit for utilization as a weapon: atomic combination.
Stars begin as gigantic districts of gas, for the most part hydrogen. This gas will begin to contract, and it warms up. As it gets, its temperature rises. At the point when the warmth gets sufficiently high, it causes the individual hydrogen iotas to impact and consolidate into helium with the arrival of vitality. This is called fusion.
Answer:
Light takes 77 minutes to travel from the Sun to Saturn.
Explanation:
The equation for the average velocity can be used to estimate the time that light will take to travel from the Sun to Saturn. The average velocity is defined as:
(1)
Where v is the velocity, d is the covered distance and t is the time.
Equation 1 can be rewritten for t to get:
It is necessary to express the speed of light in terms of minutes:
⇒ 
<em>Km/min </em>
It is known that light takes 8,3 minutes to go from the Sun to the Earth, where the distance between each other is 150.000.000 Kilometers.
Answer:
In a circuit ,<u> VOLTAGE </u>can be said to be the "source" or the "push of electrons". This push then creates what is known as a <u> CURRENT , </u>which is the flow of electric charge through the circuit. This flow can the slowed down or restricted by <u>RESISTOR </u>, and this is also what can be harnessed in order to use electric <u>ENERGY </u>.
Explanation:
Voltage:
It is the 'push' that causes charges to move in a wire or other electrical conductor, also it is a Source input to the electric circuit.
Measured in Volts.
Current:
An electric current is the rate of flow of electric charge from a point or through a region.
Measured in Ampere.
Resistor:
Resistor is used to resist the flow of charge or to resist the current called as Resistance.
Measured in Ohms.
Electric Energy:
Electrical energy is a form of energy resulting from the flow of electric charge.
Measured in Joules.
