The correct path of sperm cells through the male reproductive system is seminiferous tubules, epididymis, vas deferens, and then the urethra.

The correct path of sperm cells through the male reproductive system is from the seminiferous tubules, where they are formed, to the epididymis, where they mature and are stored. From there, during ejaculation, the sperm move through the vas deferens, which is part of the spermatic cord, towards the ejaculatory duct. Finally, the sperm cells travel through the urethra and are expelled from the body. Thus, the complete path is: Seminiferous tubules, Epididymis, Vas deferens, Urethra.

Hurricanes are intense storm in tropic regions. When hurricane makes landfall it will loss its strength and weakens . Hence option A is correct.

Hurricanes are powerful storms with a tropical origin. Small groups of disorganized storms that collect energy from the heat of the ocean water are the precursors to hurricanes.

Individual clouds will start to group together into a single storm if specific atmospheric conditions are met. The organization of the cloud clusters will intensify, and the winds will pick up and move around a particular point, the eye, if the storm keeps consuming heat from the ocean.

It is also recognized that hurricane-related extreme atmospheric conditions can give rise to tornadoes. Because they are no longer able to draw energy from the ocean when a storm makes landfall, they start to weaken. They can still harm a lot and are harmful nonetheless.

What happens when a hurricane makes a landfall; it weakens. This makes option A the right choice.

When a hurricane makes landfall, several things typically happen:

A. A hurricane will weaken after making landfall: This statement is generally true. When a hurricane moves over land, it loses its primary energy source, which is the warm ocean waters. As a result, the storm's strength tends to diminish gradually as it moves farther inland. However, hurricanes can still cause significant damage even after making landfall, especially if they are large and powerful at the time of landfall.

B. A hurricane will pick up speed after making landfall: This statement is not accurate. Once a hurricane makes landfall, it usually begins to slow down as it interacts with the friction and topography of the land. The storm's forward speed typically decreases as it moves inland.

C. A hurricane will have stronger wind speeds after it makes landfall: This statement is generally not true. As mentioned earlier, a hurricane weakens after making landfall due to the loss of its primary energy source, warm ocean waters. Wind speeds tend to decrease as the storm moves over land.

D. A hurricane will have a smaller storm surge after it makes landfall: This statement is generally true. Storm surge is the rise in sea level generated by a hurricane's winds and low pressure. When a hurricane moves over land, its ability to push seawater ashore diminishes, resulting in a reduction in the storm surge. However, storm surge can still be a significant threat near coastal areas even after a hurricane makes landfall.

Answer:Heavy rain,Strong winds,Severe lightening

Heavy rain, strong winds and severe lightning are the events which can cause damage during thunderstorm.

Answer: Option A, D and E

Explanation:

Thunderstorm is term given to occurrence of heavy rains accompanied by high sounds and lightening. As the sound is produced due to lightening, that sound is termed as thunder and the presence of heavy rain is termed as storm.

So both together is termed as thunderstorm. Thunderstorm usually occurs due to increase in moisture, temperature and when the heated air molecules are raised upward. During these thunderstorms, the occurrence of heavy rains, flow of strong winds and severe lightening are well known.

So heavy rains can lead to flash flooding and destruction of homes, strong winds will also lead to damage of objects and lightening may cause forest fire. Thus these three events during thunderstorm causes damage.

Answer:

telescope

Explanation:

Answer:

Astronomical telescope

Explanation:

A telescope is a device used to observe object that are at distant places. It is comprised of lens or mirrors (convex or concave). Light is allowed to pass through it , producing a reflected or a refracted image. The magnification of an image is directly proportional to the len's or mirror's size. A bigger lens produces a magnified and clear image as it allows more amount of light to enter the lens, whereas a smaller lens will produce a smaller image due to its smaller amount of incident light.

Thus, an astronomical telescope is a tool extensively used to view the outer space.

Explanation:

Inclined plane is a ramp or stairs.

Final answer:

The image formed by a plane mirror is virtual, upright, and of the same size as the object.

Explanation:

The image formed by a plane mirror exhibits specific characteristics. First and foremost, the image is virtual, meaning it cannot be projected onto a screen because it appears to be behind the mirror. The image is also upright, which means it has the same orientation as the actual object (it is not inverted). Moreover, the image is of the same size as the object, which differentiates it from images formed by curved mirrors that can be either magnified or diminished.

The current is “inversely proportional to resistance of circuit” and “directly proportional to voltage across the circuit”.

Answer: Option C

Explanation:

The amount of current flowing through the circuit depends upon the resistance and voltage.  

Current depends on resistance of the circuit. If there is high potential difference, the current in circuit will be high. The high resistance leads to less current.

Mathematically the relationship between voltage, current, and resistance is given as [tex]V=I \times R[/tex]. This is also stated as Ohms law.

Ionic bonds are formed between atoms of metals and nonmetals, resulting in the transfer of electrons from the metal to the nonmetal, creating a stable crystalline compound with zero net charge.

Atoms from metals and nonmetals would form ionic bonds. Ionic bonds are electrostatic attractions between positively charged ions, or cations, and negatively charged ions, or anions. These attractions lead to the formation of a crystalline lattice in which the compound has a zero net charge. For example, sodium (Na), a metal, will donate its valence electron to chlorine (Cl), a nonmetal, leading to the formation of Na+ and Cl- ions. These ions will then attract each other, forming NaCl, also known as table salt, which exhibits a stable crystalline structure.

Another example is the formation of magnesium oxide (MgO) when magnesium (Mg), a metal with two valence electrons, reacts with oxygen (O2), a nonmetal with six valence electrons. Magnesium will lose two electrons to become Mg2+, while oxygen will gain those electrons to become O2-. The resulting compound is an arrangement of oppositely charged ions held together by the force of their attraction, resulting in MgO's stable ionic crystalline structure.

Explanation:

Hope this helps

Integration of stimuli and comparison with memories and previous stimuli leads to specific responses. Behaviors can be instinctual or learned, depending on the influence of the environment.

Integration. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed. This is called integration. Stimuli are compared with, or integrated with, other stimuli, memories of previous stimuli, or the state of a person at a particular time. This leads to the specific response that will be generated. For example, when seeing a baseball pitched to a batter, the trajectory of the ball and its speed will be considered before the batter decides to swing.

Behaviors can result from this integration of stimuli. They can be instinctual or learned. Instinctual behaviors are not influenced by the environment and include mating systems and methods of communication. On the other hand, learned behaviors are influenced by the environment and include imprinting, habituation, conditioning, and cognitive learning.

Answer:

Explanation:

Well you have the voltages right, and that is no trivial matter. Each one of the resistors in a parallel circuit sees the same input voltages (in this case 6).

Now I think it would be a good idea to fill in the the resistance column.

R1 = 3 ohms

R2 = 6 ohms

R3 = 2 ohms

The total resistance can be calculated in two ways. I'll get around to doing both of them but I'll do the conventional way first. One hint: the total resistance must be smaller than the smallest resistor. Read that sentence over a couple of times. What it means is that it must be less than 2 ohms in a parallel circuit.

1/r1 + 1/r2 + 1/r3 = 1/rt

1/3 + 1/6 + 1/2 = 1/rt

Change all the denominators to 6ths.

2/6 + 1/6 + 3/6 = 1/rt

(2 + 1 + 3)/6 = 6/6  = 1

rt = 1

====================

So the current I is V/R

V = 6

R = 1

Current = V/R = 6/1 = 6 amps.

====================

The current in each resistor is

I1 = V / R1

I1 = 6/3 = 2 amps

I2 = V/R2

I2 = 6/6 = 1 amp

I3 = 6/2 = 3 amps

The total is I1 + I2 + I3 = 2 + 1 + 3 = 6 amps.

======================

Remember I said there was 2 ways of figuring out the total resistance. I did one of them about. Here's the other.

R = V / It

R = 6 / 6

R = 1 ohm just what you got before.

====================

Power

P = V * I

P1 = 6 * 2 = 12 watts

P2 = 6*1   = 6 watts

P3 = 6*3 = 18 watts

Pt =            36 watts.

Pt can be done by using the voltage * the total current

Pt = 6 volts * 6 amps = 36 watts, just what you would expect.

d, its act only ob material that are touching a magnet

The false statement about magnetic force is: it act only on materials that are touching a magnet.​ Hence, option (d) is correct.

Electromagnetic force is a result of charge motion, which also produces magnetic force. We know that a moving charge creates a magnetic field around itself. In this situation, the magnetic force can be thought of as a force that results from magnetic fields interacting.

As magnetic force is a field force, it  is expected over a distance. In every atoms, electron revolves around nucleus but a certain type of material has non-zero net magnetic momentum. Magnetic field affects only the material with non-zero net magnetic momentum. Same poles of magnets repulse whereas opposite poles of magnets attract. But due to being a field force, it  does not act only on materials that are touching a magnet - it acts all material in its surroundings .​Hence, option (d) is correct.

rotational inertia would be the right answer

The resistance of a rotating body to changes in angular velocity called rotational inertia

Answer: Option B

Explanation:

The rotational inertia of a rotating object resist the changes in the angular velocity of the object.  Whenever we try to reduce the velocity of a rotating object or try to stop its motion, we feel a force or kind of resistance in its nature.

This is because an object which rotates through an axis follows the law of inertia exerting a resistance against the external force which tries to change its motion or simply the angular velocity.

Heavier bodies have more rotational inertia as compared to the lighter ones because of its mass. This kind of inertia is known as the “Moment of Inertia” formulated as,

              [tex]J_{0}=\sum m_{i} r_{i}^{2}[/tex]

Earth's gravity attempts to change the velocity of all objects on Earth's surface toward the center of the Earth at a rate of 9.8 meters per seconds squared.

Explanation:

Answer:

Earth's gravity attempts to change the velocity of all objects on Earth's surface toward CENTER OF EARTH at a rate of 9.8 meters per seconds squared.

Explanation:

As we know that the gravitational force of Earth is towards the center and it is given by the formula

[tex]F = \frac{GMm}{R^2}[/tex]

this is the force experienced by all the objects near the surface of Earth and this force is towards the center of the Earth

So this is also know as gravity of Earth

Now we know that the acceleration of objects near the surface of Earth is given by the equation

[tex]a = \frac{F}{m}[/tex]

[tex]a = \frac{GM}{R^2}[/tex]

this is also known as acceleration due to gravity and this is of magnitude g = 9.8 m/s/s

so all objects will move towards the center of earth with rate of change in velocity of 9.8 m/s/s
