Bohr's atomic model may have not been the accurate atomic model we have in the present, but he helped paved the way for accurate discoveries. His model is also called the planetary model. The nucleus, containing the neutrons and protons are situated at the center of the atom. The electrons are orbiting around the nucleus. The model is illustrated as shown in the attached picture.
Answer:
Each student will need;
1 red jelly bean, 1 white jelly bean, 1 black jelly bean and 3 red jelly beans.
Explanation:
Sodium bicarbonate molecule, NaHCO3, or baking soda is composed of the following:
1 atom of sodium, Na;
1 atom of hydrogen, H;
1 atom of carbon, C, and
3 atoms of oxygen.
For each of the models to be built by the two students, these atoms are to be represented accordingly.
Since Red jelly beans represent sodium atoms (Na), white jelly beans represent hydrogen atoms (H), black jelly beans represent carbon atoms (C), and blue jelly beans represent oxygen atoms (O), each student will need;
1 red jelly bean, 1 white jelly bean, 1 black jelly bean and 3 red jelly beans.
A sample model is found in the attachment below:
Scott traveled 10 miles in his journey.
<u>Explanation</u>:
Scott first travels 5 miles in north direction, then he turns to west and covers 3 miles distance finally he turns to south and travels 2 miles. We need to find the total distance covered by the Scott. To find the distance we should sum up all the distances he covered in three directions 5 miles north + 3 miles west + 2 miles south = 10 miles.
Therefore we can conclude that the total distance traveled by the Scott is 10 miles.
KE = mv2

KE = ? J
m = 1.5 kg
v = 55 m/s
KE = 1.5 kg x (55 m/s)2

KE = 2,268.75 J
Answer:
Magnification is the number of times larger an image is compared with the real size of the object.
Magnification = Image / Actual = 5/0.4 =12.5
