Final answer:

The Earth's crust is composed of igneous, metamorphic, and sedimentary rocks, examples of which include granite (igneous), basalt (igneous), and limestone (sedimentary).

Explanation:

The three types of rock in the Earth's crust are igneous, metamorphic, and sedimentary. Igneous rocks, like granite and basalt, form when magma or lava cools and solidifies. Sedimentary rocks form from the compaction and cementation of various substances, including pre-existing rock fragments or mineral precipitation. Limestone is an example of a sedimentary rock formed from precipitated minerals. Metamorphic rocks arise from the transformation of existing rock types through heat and pressure, resulting in a change in mineral composition or structure.

Answer:

The answer is: Many are associated in pairs, trios, groups or clusters, and their distribution in filamentary structures.

Explanation:

Galaxies rarely appear isolated and their distribution in the Universe is not uniform. Many are associated in pairs, trios, groups of some tens or clusters of up to a few thousand. These groups are held together by gravitation.

The large-scale distribution of galaxies seems to indicate that they are concentrated along large filamentary structures.

The answer is: Many are associated in pairs, trios, groups or clusters, and their distribution in filamentary structures.

The strength of the electric field of a charged particle becomes greater as the distance from the particle increases. this statement is False.

Electric field is field around electrically charged particle where columbic force of attraction or repulsion can be experienced by other charged particles. It is denoted by letter E and it's SI unit is V/m Volt per meter or N/C newton per coulomb. Electric field comes inward to the center of the negative charge and it is going outward for positive charge. Electric field E is given by E = F/q where F is columbic force experienced by the unit charge.

Electric around a charge having magnitude q is given by

[tex]E = \frac{1}{4\pi r^{2} } \frac{q}{r^{2} }[/tex] where r is the distance from the center of the charge.

from formula we can see that as distance increases electric field decreases because electric field is inverse function of distance r.

Hence above statement is false.

The amount of water given to each plant would be considered an independent variable. Therefore option C is correct.

An independent variable is a factor that the researcher deliberately manipulates or changes in an experiment to observe its effect on the dependent variable.

In this case, the independent variable is the amount of time spent in the sunlight. The researcher intentionally varies the exposure to sunlight between the two plants.

Therefore, the amount of water given to each plant is a control or constant, while the amount of time spent in the sunlight is the independent variable in this experiment.

If you opened the valve on a bicycle tire, the air inside of the tire will come out and the pressure it exert will be less.

When air is pumped into a bicycle tube, the tube gets inflated due to the air pressure exerted by the collisions of gas molecules in air with the inner walls of the rubber tube. This air pressure makes the tyres feel hard.

When the temperature cools down, the air within the tire shrinks. In the same way, when the temperature rises, the air within the tire expands.

Due to the air being compressed in a small space, the air is pressurized and when the valve is open it causes a loss in pressure making the air gush out.

The acceleration due to gravity, or g (exp), will decrease if the experiment is conducted 10 kilometers above sea level. This is because the force of gravity reduces as you move further from the Earth's surface.

The acceleration due to gravity, or g (exp), is expected to decrease if the experiment is repeated at a place 10 kilometers above the sea-level. This is because the force of gravity decreases as the distance from the center of the Earth increases.

Essentially, the further you move away from the Earth's surface, the weaker the gravitational force gets. This is due to the fact that gravity is dependent on distance. So, being 10 kilometers above sea level would result in a slightly lower acceleration due to gravity.

The basketball is thrown horizontally and the time of flight is approximately 0.648 seconds.

In this problem, a basketball is passed from one player to another at the same level. The initial speed of the ball is 7.1 m/s and it travels a distance of 4.6 m. To determine the initial direction of the ball, we need to consider that the ball is caught at the same level from which it was thrown, meaning it has no vertical displacement. Therefore, the initial direction of the ball is horizontal.

To find the time of flight, we can use the equation:

time = distance / speed

Plugging in the values given:

time = 4.6 m / 7.1 m/s = 0.648 s

So, the time of flight of the ball is approximately 0.648 seconds.

Final answer:

Inertia is the property of an object to maintain its state of motion or rest unless acted upon by a net external force, as described by Newton's first law of motion. This law, also known as the law of inertia, indicates that an object will continue in its state of constant velocity unless a force causes a change.

Explanation:

How is Inertia Related to Newton's First Law of Motion?:

Inertia is directly related to Newton's first law of motion, often referred to as the law of inertia. Newton's first law states that a body at rest remains at rest, and a body in motion remains in motion at a constant velocity unless acted upon by a net external force. This tendency of an object to resist changes in its state of motion or rest is known as inertia. Essentially, inertia is the reason why an object remains at rest or carries on moving at the same speed in a straight line unless a net force acts upon it.

Newton's laws are fundamental in the study of motion under the influence of forces, particularly in inertial frames of reference. Forces, which are described by Newton's laws, are always vectors with both magnitude and direction, and arise from interactions among objects. Newton's first law serves as a definition of an inertial frame of reference, and thus, any frame where the law is valid is considered inertial.

Answer:

Time of flight, t = 1.71 seconds

Explanation:

It is given that,

Speed of the soccer ball, u = 15.6 m/s

Angle made with the horizontal, [tex]\theta=32.5^{\circ}[/tex]

Let t is the time for which the ball was in the air. The time duration for which the ball is in air is called the time of flight of the projectile. It is given by :

[tex]t=\dfrac{2u\ sin\theta}{g}[/tex]

[tex]t=\dfrac{2(15.6)\ sin(32.5)}{9.8}[/tex]

t = 1.71 seconds

So, the ball was in the air for 1.71 seconds. Hence, this is the required solution.

To find the amount of time the soccer ball was in the air, we can break the initial velocity of the ball into its horizontal and vertical components. The time in the air can be calculated using the vertical velocity component and the vertical distance traveled.

To find the amount of time the soccer ball was in the air, we can break the initial velocity of the ball into its horizontal and vertical components. The horizontal component will remain constant throughout the motion, while the vertical component will change due to the force of gravity.

Using the initial velocity of 15.6 m/s and the angle of 32.5 degrees above the horizontal, we can find the vertical velocity component using trigonometry. The vertical velocity component is given by Vy = V * sin(θ), where Vy is the vertical velocity, V is the initial velocity, and θ is the angle above the horizontal.

With the vertical velocity component, we can calculate the time the ball was in the air by dividing the vertical distance it travels by the vertical velocity. Since the ball lands at the same level, the vertical distance can be assumed to be zero. Therefore, the time in the air is given by Δt = 2 * (Vy / g), where Δt is the time in the air, Vy is the vertical velocity component, and g is the acceleration due to gravity (approximately 9.8 m/s²).
