Answer:
The correct answer is option b, that is, when the Sun, Earth, and the moon are nearly in a line.
Explanation:
The low and high tides are caused by the moon. The gravitational force of the moon produces something known as the tidal force. This force makes the Earth and its water to bulge out on the side nearest to the moon and the side far away from the moon. These bulges of water are considered as high tides.
Similarly to the moon, the Sun also causes tides, but, they are smaller in comparison. However, when the Earth, moon, and the Sun line up, that is, which takes place during the new moon or the full moon, the solar and lunar tides reinforce each other, resulting in more extreme tides, known as spring tides. The spring tides are considered as the highest tides.
O A. lonic
B. Metallic
OC. Macromolecular
D. Chemical

The correct answer is option B. Metallic.
Metal is composed of a huge structure of atoms arranged in a regular pattern. Electrons from the outer shell of a metal atom are delocalized and can move freely throughout the structure. This sharing of delocalized electrons results in strong metal bonds.
Metallic bonds are electrostatic attraction between metal cations and the negatively charged ocean of delocalized electrons. The sea of delocalized electrons contains only valence electrons, not core electrons.

Answer:
1) The dilution scheme will result in a 200μM solution.
2) The dilution scheme will not result in a 200μM solution.
3) The dilution scheme will not result in a 200μM solution.
4) The dilution scheme will result in a 200μM solution.
5) The dilution scheme will result in a 200μM solution.
Explanation:
Convert the given original molarity to molar as follows.
Consider the following serial dilutions.
1)
Dilute 5.00 mL of the stock solution upto 500 mL . Then dilute 10.00 mL of the resulting solution upto 250.0 mL.
Molarity of 500 mL solution:
10 mL of this solution is diluted to 250 ml
Convert μM :
Therefore, The dilution scheme will result in a 200μM solution.
2)
Dilute 5.00 mL of the stock solution upto 100 mL . Then dilute 10.00 mL of the resulting solution upto 1000 mL.
Molarity of 100 mL solution:
10 mL of this solution is diluted to 1000 ml
Convert μM :
Therefore, The dilution scheme will not result in a 200μM solution.
3)
Dilute 10.00 mL of the stock solution upto 100 mL . Then dilute 5 mL of the resulting solution upto 100 mL.
Molarity of 100 mL solution:
5 mL of this solution is diluted to 1000 ml
Convert μM :
Therefore, The dilution scheme will not result in a 200μM solution.
4)
Dilute 5 mL of the stock solution upto 250 mL . Then dilute 10 mL of the resulting solution upto 500 mL.
Molarity of 250 mL solution:
10 mL of this solution is diluted to 500 ml
Convert μM :
Therefore, The dilution scheme will result in a 200μM solution.
5)
Dilute 10 mL of the stock solution upto 250 mL . Then dilute 10 mL of the resulting solution upto 1000 mL.
Molarity of 250 mL solution:
10 mL of this solution is diluted to 1000 ml
Convert μM :
Therefore, The dilution scheme will result in a 200μM solution.
the answer is curie
curie- a unit of radiation equal 3.7x10^10 disintegratons persecond
B. Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s.
C.Beverly accelerated at a greater rate for the entire race.
D. Carl accelerated at a greater rate for the entire race
The correct option is B.
Acceleration is defined as the rate of velocity of a body per unit time; that is, acceleration is given by the ratio of velocity and time. Looking at the graph given above, it can be seen that, the two runners started with different initial velocity; Beverly started with the initial velocity of 15 m/s while Carl started with the initial velocity of 10 m/s. For the rest of the race, the two runners maintains similar acceleration but Beverly won because her initial velocity was higher.
