Explanation:

10 m/s to the right is an example of the velocity of an object. Thus, the correct option is B.

Velocity can be defined as the directional speed of an object which is in motion as an indication of the rate of change in the position of an object as observed from a particular frame of reference by the observer and it is measured by a particular standard of time.

Velocity is a vector quantity. This is because, velocity has both the magnitude and direction. The SI unit of velocity is meter per second. The velocity of an object can be calculated by the formula:

Velocity = Displacement/ Time

Therefore, the correct option is B.

TO solve this problem, we simply need to use ratio and proportion. From the statement problem we can say the ratio height : distance, so that: (let us say that X is the image distance)

15 cm : 30 cm = 10 cm : X

We know that the symbol : means division so:

15 cm / 30 cm = 10 cm / X

X = 10 cm * 30 cm / 15 cm

X = 20 cm

So the image distance is 20 cm

Answer: To hit the target fish must spit with the velocity of 7.30 m/s.

Explanation:

Highest point of the trajectory = H = 2 m

Angle at which archer fish spit = θ = 60°

Acceleration due to gravity = g = 10 [tex]m/s^2[/tex]

The maximum height of the projectile is given as:

[tex]H=\frac{u^2\sin^2\theta }{2g}[/tex]

[tex]2 m=\frac{u^2\sin^2(60^o)}{2\times 10 m/s^2}[/tex]

[tex]u^2=\frac{2 m\times 2\times 10 m/s^2\times 4}{3}=53 m^2/s^2[/tex]

[tex]u=7.30 m/s[/tex]

To hit the target fish must spit with the velocity of 7.30 m/s.

Final answer:

The gravitational potential energy (G.P.E.) of a 675-newton climber at the top of a 3,050-meter mountain is calculated as 2,058,750 Joules.

Explanation:

To calculate the gravitational potential energy (G.P.E.) of a 675-newton climber at the top of a 3,050-meter mountain in Colorado, we use the formula G.P.E. = weight × height × acceleration due to gravity (g = 9.8 m/s²). Assuming that the weight given is the force due to gravity on the climber, the weight already accounts for the gravitational acceleration, so we do not need to multiply by 9.8 m/s² again. Therefore, the G.P.E. is simply the product of the weight and the height.

G.P.E. = 675 N × 3,050 m

G.P.E. = 2,058,750 Joules

Thus, the climber has a gravitational potential energy of 2,058,750 Joules at the top of the mountain.

Answer:

Rutherford brought the concept of a nucleus. He said that the atom "had a tiny and heavy nucleus."

Objects of the same mass on different planets will have different weights depending on the local gravity. An object will weigh more on Planet A with stronger gravity than on Planet B with weaker gravity, even though the mass is constant.

Two objects with the same mass on different planets will have different weights if the planets have different strengths of gravitational force. On Planet A, where the force of gravity is stronger, an object will weigh more compared to its weight on Planet B, where the force of gravity is weaker. This is because weight is the force exerted by the gravitational field of a planet on an object, which can be calculated using the equation F = ma, where m is the mass and a represents the acceleration due to gravity (g) on that planet. Therefore, if gravity is stronger on Planet A, the acceleration due to gravity is greater, resulting in a greater weight for the object, even though its mass remains unchanged.

The weights of two objects with the same mass will differ on different planets due to varying gravitational forces. The object on the planet with the stronger gravitational force will weigh more.

The weights of objects depend on both their mass and the gravitational force acting upon them. Since both objects have the same mass but are on different planets with different gravitational forces, their weights will differ.

Specifically, the object on Planet A, which has a stronger force of gravity, will weigh more than the object on Planet B, which has a weaker gravitational force.

Weight is calculated by the equation:

Weight = Mass × Gravitational Force

If the gravitational force on Planet A is stronger, then for the same mass, the weight will be greater. For example, if an object has a mass of 10 kg and Planet A has a gravitational force of 15 N/kg, the weight will be:

Weight = 10 kg × 15 N/kg = 150 N

If the same object is on Planet B with a gravitational force of 10 N/kg, then the weight will be:

Weight = 10 kg × 10 N/kg = 100 N

Thus, even though the mass of the objects is the same, their weights are different due to the different gravitational forces on each planet.

Light is the major component required by marine organisms. The penetration of the light varies with the depth of the ocean.

The penetration of the light rays decreases with an increase in depth. The light is unable to breach below 1000 to 1200 meters.

The light effect on the ocean can be explained as:

1. The seawater absorbs the red, orange, and yellow wavelengths, which causes the blue light to penetrate farther into the ocean. It gives the ocean its distinctive blue color.

2. The water absorbs the light rays as it penetrates deep into the ocean. The light rays get completely absorbed before it reaches the ground of the ocean.

3. The light cannot penetrate deep within the ocean, thus, the deep lengths of the ocean are still unknown to humans.

Thus, the light penetration decreases with an increase in the depth of the ocean.

Explanation:

Explanation:

The food chain consists of autotrophs (producers) and heterotrophs (consumers). All animals and plants fall into these categories.

The autotrophs are the first stage of the food chain. They are mostly plants. They use the radiation from the sun to fulfill their energy needs. In doing this process the autotrophs release oxygen. The process is known as photosynthesis. The plants take in carbon dioxide in the atmosphere released by heterotrophs during respiration and the plants in turn release carbon dioxide. Also, autotrophs provide a food source for the heterotrophs.

Every producer and consumer interact in some way, completing food chain.

Final answer:

The correct order of increasing size from smallest to largest is: electron, proton, nucleus, atom. Electrons are the smallest particles in this list and form the cloud around the nucleus, which is made of larger protons and neutrons. Atoms include both the nucleus and the electron cloud, making them the largest structures listed.

Explanation:

In order to rank the following from smallest to largest in size, we need to understand the structure of an atom. An atom consists of a central nucleus, which contains protons and neutrons, surrounded by a cloud of electrons.

An electron is the smallest particle among the ones listed. It is part of the cloud around the nucleus and has a negative charge. A proton is a positively charged particle that is one of the components of the nucleus and is larger than an electron. The nucleus, which consists of both protons and neutrons, is significantly larger than a single proton. The atom, consisting of the nucleus and electron cloud, is the largest of all listed components.

It is important to note that while protons and neutrons have roughly the same size, the nucleus varies in size depending on the number of protons and neutrons it contains. Electrons, on the other hand, being much smaller, do not contribute significantly to the overall size of the atom.
