Answer:
v = 895 m/s
Explanation:
Time period is given as 39 Earth Days
now the radius of the orbit is given as
so the total path length is given as
now the speed will be given as
Answer:
During a chemical reaction, Bromine (Br) would be expected to <u><em>gain 1 valence electron to have a full octet.</em></u>
Explanation:
In the periodic table the elements are ordered so that those with similar chemical properties are located close to each other.
The elements are arranged in horizontal rows, called periods, which coincide with the last electronic layer of the element. That is, an element with five electronic shells will be in the fifth period.
The columns of the table are called groups. The elements that make up each group coincide in their electronic configuration of valence electrons, that is, they have the same number of electrons in their last.
The elements tend to resemble the closest noble gases in terms of their electronic configuration of the last layer, that is, having eight electrons in the last layer to be stable.
Bromine belongs to group 17 (VII A), which indicates that it has 7 electrons in its last shell. So bromine requires more energy to lose all 7 electrons and generate stability, than it does to gain 1 electron and fill in 8 electrons to be stable. So:
<u><em>During a chemical reaction, Bromine (Br) would be expected to gain 1 valence electron to have a full octet.</em></u>
If the bulb is in series with something else, then . . .
-- The brightness of the bulb depends on the <em>other</em> device in the circuit.
-- If the other device is designed to use <em>less power</em> than the bulb, then the
other device gets <em>more power</em> than the bulb gets.
-- If the other device is designed to use <em>more power </em>than the bulb, then the
other device gets <em>less power</em> than the bulb gets.
-- If the other device is removed from the circuit, then the bulb doesn't light at all.
This description of the often-screwy behavior of a series circuit may partly explain
why the electric service in your home is not a series circuit.
Answer:
Golf ball A was hit with a weaker force
Explanation:
Golf ball B went a larger distance than golf ball A, so we could think friction affected golf ball A rather than golf ball B. That is why the first two choices are wrong.
The strongest forced applied made golf ball B go further.
Force in Newtons =
(1200)•(the rate of acceleration you want)
It depends on how fast you want to accelerate.
