Answer:
moving
Explanation:
They've been moving for thousands and thousands of years. Millions of years ago there was a land called Pangea that seperated into the continents we see today.
Answer: There is two (PO4) in the formula
Explanation:
Just be aware of the difference between numbers to the right and left: 5Mg3 means there are a total of 5 Mg (if 3 is a number in the bottom left) the 3 in (PO4) means there are 3 PO4 but because of the 2 it could mean there are 6.
Depends if the elements are separated
Answer:
The answer is explained below.
Explanation:
The energy emitted during the de-excitation of an electron from a higher energy level to a lower energy level is directly proportional to the frequency of the emitted light.
Here, the total sum of the energies of 2 frequencies of light emitted in different stages is equal to the energy of a single frequency of light during the de-excitation of fourth level to ground level directly.
Hence the total sum of of the frequencies of 2 lights emitted in different stages is equal to the frequency of single frequency of light emitted during the de-excitation from fourth level to ground level directly.
The some of the energies of 2 frequencies emitted by one electron is equal to the energy of a single frequency when electron jumps directly.
Answer:
768000 joule
Explanation:
As we know that
K.E = 0.5 x mv2
Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position.
putting the value we get
K.E = 0.5 x (1500KG)(32 m/s)2
K.E =768000 J
Plants rely on proper soil conditions to give them nutrients and minerals.
