Which equation can be used to calculate the normal force on an object if you know the speed of the object, the coefficient of kinetic friction, and the force of kinetic friction on the object?

Answers

Answer:

D

Explanation:

The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.

The equation that we can used to determine the frictional force using the coefficient of kinetic friction and the normal force is given by the expression : F = u N.

Where N is the normal force by the weight of the body.

What is frictional force?

Frictional force is a type of force acting on a body to prevents its motion. Hence, the frictional force is always negative. Frictional force acting on an object is making a resistance to the motion of the object.

There are both kinetic frictional force and static frictional force. The coefficient of frictional force is the ratio of the frictional force to the normal force on the object. The normal force on the object is equal to m g that is the force by its own weight.

If u is the coefficient of kinetic friction and N be the normal force acting on the object, then the force of kinetic frictional force F is given by,

F = u N.

Where N = mg.

Answers

The North America will not be able to view the eclipse because of its location on the earth caused by the tilting of the earth.

Effect of tilting of the Earth

The tilt of the Earth is what causes seasons to occur. These are the seasons in relation to the Northern Hemisphere.

The tilting of the Earth causes the difference in the amount of sun reaching each region of the earth like in the North America continent.

What is the volume of the cone?

Answers

Answer:

42.417 cm³

Explanation:

The formula to find the volume of a cone is :

V = [tex]\frac{1}{3}[/tex] × π r² h

Here,

r ⇒ radius ⇒ 3 cm

h ⇒ height ⇒ 4.5 cm

Let us find it now.

V = [tex]\frac{1}{3}[/tex] × π r² h

V = [tex]\frac{1}{3}[/tex] × π × 3 × 3 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 40.5

V = [tex]\frac{1}{3}[/tex] × 3.142 × 40.5

V = [tex]\frac{1}{3}[/tex] × 127.251

V = 42.417 cm³

Combustion is when you use oxygen to convert fuel to heat and light energy. Option B is correct.

What is combustion?

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives heat.

The fuel can be a solid, liquid, or gas.

For example, charcoal is combined with oxygen.

Combustion is commonly called burning, and the substance that burns is usually referred as fuel.

For combustion to occur few things must be present:

fuel to be burned.

A source of oxygen

A source of heat.

Where [tex]R_1[/tex] = 6Ω and [tex]R_2[/tex] = 12Ω

Finding [tex]R_T\\[/tex]:

[tex]\displaystyle \frac{1}{R_T} =\frac{1}{6} +\frac{1}{12} \\\\\frac{1}{R_T} =\frac{1 \times 2+1}{12} \\\\\frac{1}{R_T} =\frac{3}{12} \\\\\frac{R_T}{1} = \frac{12}{3} \\\\\boxed{R_T=4 \ Ohm}[/tex]

Explanation:

Answer:

1. In sports.

2. In programming or Animation.

3. In home appliances.

4. In military.

Explanation:

1. In sports. Being common in sports, projectile motion is applied in motion of a projectile which is usually a ball. This is because we are able to calculate the angle of the flight developed by a ball to maximize its distance or velocity. For example in baseball and basketball.

2. In programming or Animation. Considering that there is a challenge for animators and programmers in modern world, physics is applied in televisions or video games. For example a baseball being hit by a player in video game or TV, it should look real. Hence the application of projectile motion.

3. In home appliances. Appliances for example hose or water gun uses an application of projectile motion. As the water exits the hose or water gun, the angle over which the water travels depends on the distance moved and force that is being applied.

4. In military. Bullets being shot from the barrel of the gun is a projectile in air. The speed of the bullet is higher than that of the water exiting the hose therefore it will travel a longer distance. The manufacturers of weapons such as a gun tries to maximize the speed while minimizing gun's recoil.

Which marine habitats would have the least access to primary producers?

d.

Please select the best answer from the choices provided

A

D

Answers

Answer:

D

Explanation:

Deep sea and sea floor marine habitats would have the least access to primary producers. The correct option is (d).

Primary producers would have the least access to habitats in the deep sea and on the ocean floor. Primary producers are animals and plants that can use sunlight as an energy source to photosynthesize and make their own food, including algae and phytoplankton.

Because of the depth of the water, light penetration is constrained in the deep sea and sea floor settings, making it difficult for creatures that rely on photosynthesis to survive.

In comparison to other maritime ecosystems, where sunlight is more easily obtainable, such as coral reefs, lagoons, salt marshes, estuaries, mangroves, and intertidal zones, these habitats often have lower amounts of primary production.

Therefore, The correct option is (d) deep sea and sea floor.

What does that mean about the densities of the phases of water?

The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state

Answers

The correct option is 2. The solid state is more dense than the liquid state.

The solid form of most substances is denser than the liquid phase so a block of most solids will sink in the liquid but a block of ice floats in liquid water because ice is less dense. Upon freezing the density of water decreases by about 9%. This is due to cooling of intermolecular vibrations allowing the molecules to form steady hydrogen bonds and locking into positions of hexagonal packing upon freezing to ice. These bonds are shorter in the crystal than in the liquid.

Doppler effect

The Doppler effect is defined as the change in the apparent frequency of a wave produced by the relative motion of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.

In summary,  there is always a change in the frequency of sound as the source of the sound moves towards or away from the observer. So, the Doppler Effect is an alteration of the observed frequency of a sound due to the movement of the source or the observer, that is, they are changes in the frequency and wavelength of a wave due to the relative movement between the wave source and the observer.

Changes on the frequency

In this case, considering the Doppler effect, the frequency heard by the student would change if:

C. They move at the same speed and in the same direction.
D. They move at the same speed but in random directions?

Answers

When a substance changes from a liquid to a solid, they move more slowly and become fixed in position. Option A is correct.

When a substance changes from a liquid to a solid, its particles lose energy and move more slowly. As the temperature decreases, the particles lose kinetic energy and start to arrange themselves into a fixed, ordered pattern. This causes the substance to solidify and the particles become fixed in position.

The transition from a liquid to a solid state is called freezing or solidification. During this process, the particles lose energy and their motion becomes more restricted, causing them to move more slowly and eventually become fixed in position. Option A is correct.
