olga55 [171]

The diagram best shows the magnetic field around the bar magnet is the diagram in option B.

<h3>What is the magnetic field?</h3>

The magnetic field refers to the region in space where the influence of a magnet can be felt. We know that strength of magnet can be seen by following the magnetic lines of force. The more the magnetic lines of force, the stronger the magnetic field especially when the line are packed closely together.

Looking at the diagrams of the magnetic lines of force, it must be recalled that the magnetic lines of force runs from the north pole to the south pole and not the other way round.  

Thus, the diagram best shows the magnetic field around the bar magnet is the diagram in option B.

How would you prepare 175 mL of a 0.350kmol/m^3 calcium nitrate solution
SVEN [57.7K]
0,35 kmol/m³ = 0,35 mol/dm³ = 0,35 mol/L
175 mL = 0,175 L
*-*-*-*-*-*-*-*-*-*-*-*
C = n/V
n = 0,35×0,175
n = 0,06125 mol

mCa(NO₃)₂: 40+(14×2)+(16×6) = 164 g/mol

1 mol --------- 164g
0,06125 ---- X
X = 10,045g

To prepare 175 mL of 0,35M solution, add 10,045g of calcium nitrate and add water to a volume of 175ml.

How many milliliters of a 0.266 m lino3 solution are required to make 150.0 ml of 0.075 m lino3 solution?
Allisa [31]

We need an equation that would relate the concentration of the original solution to that of the desired solution. To solve this we use the equation expressed as follows, 

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

M1V1 = M2V2

0.266 M x V1 = 0.075 M x 150 mL

V1 = 42.29 mL


Therefore, we need about 42.29 mL of the 0.266 M of lithium nitrate solution to make 150.0 mL of the 0.075 M lithium nitrate solution.

Describe the radial velocity curve. What is its shape? What is its amplitude? What is the orbital period?
lutik1710 [3]

Answer:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m )

Curve amplitude : This is the maximum value of the radial velocity curve

Radial velocity shape ; The shape of Radial velocity curve is parabolic in nature

Orbital period : Orbital period is the time taken by the star  to make one complete rotation in its orbit

Explanation:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m ) while Curve amplitude  is the maximum value of the radial velocity curve also The shape of Radial velocity curve is parabolic in nature. and  Orbital period is the time taken by the star  to make one complete rotation in its orbit

If the sun was 1 meter (about 3 feet) in size the earth would be __________ meters away
Vera_Pavlovna [14]

Answer:

The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it.
