[tex]\huge\boxed{\sf Current = 6\ Ampere}[/tex]

Explanation:

In a parallel circuit, Total resistance is:

[tex]\displaystyle \frac{1}{R_T} =\frac{1}{R_1} +\frac{1}{R_2}[/tex]

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

[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]

We know that:

V = 24 V, R = 4 Ω (V given, R found)

24 = I(4)

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.

Explanation:

Considering the Doppler efect, the frequency heard by the student would change if:

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.

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

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

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.

Answer:

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.

Answer:

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.

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.

Motion of an object that travels in a curved path under the influence of Earth's gravitational field. Examples include throwing a ball, javelin throw, and golf ball.

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.
