Answer:

As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases

Explanation:

Since the static frictional force between the block and the plane is given by F = μN where

μ = coefficient of static friction and

N = normal force on plane = component of weight of block perpendicular to the plane = Wcosθ where

W = weight of block and

θ = angle of inclined plane

Now, F = μN

F = μWcosθ

Since μ and W are constant, we see that

F ∝ cosθ and cosθ ∝ θ

So, F ∝ θ

Since the static frictional force is directly proportional to the angle the plane makes with the horizontal, when the angle the plane makes with the horizontal is increased, the static friction between the block and the plane increases.

So, As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases

Answer: 2 m/L

Explanation: If there is 50g in every m/L and you need 100g, you can take the 100g / 50g, and you have 2, meaning two sets of 50 grams, or in this case to m/L of medicine, because each m/L has 50 grams of medicine in it.

Answer:

a dark-colored fur to catch their prey

Explanation:

In areas covered with snow, the temperatures are too low. Therefore, animals surviving in these areas require thick fur or body insulation to ensure their body temperature is regulated. The snow is white in color and therefore, being white in color helps the animals camouflage hence not visible to the predators.

Having a dark color, this will only expose these animals to their predators since the areas are covered with white snow. They will be easily traced by their predators and maybe selected out by nature.

Intermolecular forces

Explanation:

Intermolecular forces cause surface tension.

Source info:
"Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions."

(11.S: Liquids and Intermolecular Forces (Summary)https://chem.libretexts.org )

Surface tension is said to be the result of the attraction between the particles present on the surface layer of the liquid matter. It is caused by intermolecular interactions. Thus, option b is correct.

Intermolecular interactions are the forces that are said to be secondary forces and allow the molecules to bond and interact together by the attractive and repulsive forces between the ions and the atoms.

The hydrogen bonds, ion-dipole, dipole-dipole, and dispersion forces are intermolecular interactions. They are not within but in between the molecules. They give rise to the surface tension in liquids that act cohesive and bind the various molecules in liquid together.

Therefore, option b. the intermolecular forces cause surface tension in liquids.

The minimum volume of 0.2M sodium sulfide that will precipitate out aluminum from 50.0 mL, 0.25 M aluminum nitrate would be 0.094 L or 94 mL

From the equation of the reaction:

[tex]2Al(NO_3)_3 + 3Na_2S ---> Al_2S_3 + 6NaNO_3[/tex]

Mole ratio of Na2S and Al(NO3)3 = 3:2

Mole of 50.0 mL, 0.25 M Al(NO3)3 = 50/1000 x 0.25

                                                         = 0.0125 mole

Equivalent mole of Na2S = 3/2 x 0.0125

                                         = 0.0188 mole

Volume of 0.2M, 0.0188 mole Na2S = 0.0188/0.2

                                                          = 0.094 L or 94 mL

Answer:

magnetic Flux ropes

Explanation:

Magnetic flux ropes (also known as coronal loops and solar prominences) sit on the surface of the sun, with matter and energy flowing through them, for hours or days.

The heat of reaction is 180 kJ/mol hence the reaction is endothermic.

Bond energy is the energy that is required to form a bond and must be supplied in order to break the bond. In the question, we are told that the energy of the reactants is 860 kJ/mol and the bond energy of the products is 680 kJ/mol.

Heat of reaction = Bond energy of reactants - Bond energy of products

= 860 kJ/mol - 680 kJ/mol = 180 kJ/mol hence the reaction is endothermic.

C)Plasma

.............this was for 20 characters to submit the answer-dont mind this

Matter exists in three different physical states, namely solid, liquid and gaseous state. The plasma is also an another state of matter. The correct option is C.

The plasma is defined as the fourth state of matter. It is a hot ionized gas which consists of approximately equal numbers of positively charged ions and negatively charged electrons. It is not same as the neutral gas.

Since plasma contains electrically charged particles, they are strongly influenced by the magnetic and electric fields while the neutral gases are not. Like gases plasmas have no fixed volume or shape.

The density of plasma is also found to be less than solids or liquids. The plasma is known as a charged gas with strong electrostatic interactions. It is the plasma which make up the sun and stars and it is the most common state of matter in the universe as a whole.

Thus the correct option is C.
