What role did gravity play in the formation of the planets?
A.
Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.
B.
The gravity of the Sun was too weak to hold it together, and large pieces of the Sun broke off to form the planets.
C.
Planet-sized bodies passing by the solar system were pulled in by Earth's gravity and fell into orbit around the Sun.
D.
The gravitational forces inside small asteroids pushed outward, causing the asteroids to swell to the size of planets.
Answer:
Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.

What percentage of Earth's water is found in glaciers?
Final answer:
Glaciers and ice caps hold about 68.7% of Earth's fresh water, with most freshwater being stored in Antarctica and Greenland. They are essential parts of the water cycle and are vital fresh water reserves that could be affected by global warming.
Explanation:
Approximately 68.7% of Earth's fresh water is contained within glaciers and ice caps, with the vast majority of that - 90% in Antarctica, 9% in Greenland, and the remaining 1% scattered in other alpine regions. Glaciers play a crucial role as they hold about 69% of the world's fresh water, highlighting their importance in the global water cycle and as reserves of fresh water. As the Earth's climate warms, these glaciers are melting at an accelerated pace, which could significantly affect water supplies and sea levels worldwide.
The distribution of water on Earth is predominantly in the oceans, with about 97% being salt water. Freshwater accounts for only 3% of the Earth's water, with glaciers and polar ice caps comprising most of this freshwater. The potential melting of this ice due to global warming poses a serious threat to coastal cities and freshwater systems.

What is the difference between a convergent and divergent plate boundary
Answer: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where the crust is destroyed as one plate dives under another.
In addition, convergent boundaries form earthquakes and volcanoes, while divergent boundaries form seafloor spreading.
Explanation:
Divergent boundaries involve plates moving apart and creating new crust, whereas convergent boundaries involve plates moving toward each other, often resulting in subduction and the destruction of crust.
Divergent Plate Boundaries:
Definition: At a divergent plate boundary, two tectonic plates move away from each other.
Formation: This movement creates a gap between the plates, and magma from the mantle rises to fill this gap, creating new crust as it cools and solidifies. This is why they are sometimes called constructive boundaries.
Examples:
An example of a divergent boundary between oceanic plates is the Mid-Atlantic Ridge, where the Eurasian Plate and the North American Plate are moving apart.An example of a divergent boundary on continental plates is the East African Rift, where the African Plate is splitting into smaller tectonic plates.Convergent Plate Boundaries:
Definition: At a convergent plate boundary, two tectonic plates move toward each other.
Formation: When these plates collide, the denser plate is often forced beneath the less dense plate in a process called subduction. This destruction of the crust is why they are sometimes called destructive boundaries.
Examples:
An example of a convergent boundary between an oceanic and a continental plate is the boundary between the Pacific Plate and the North American Plate, forming the Cascade Mountain Range.Another example is the collision between the Indian Plate and the Eurasian Plate, which has formed the Himalayas.A remote-controlled car is moving in a vacant parking lot.

Assume that the light from the flashlight is light from a star. Identify the spot where the light from this “star” is most concentrated.
The spot where the light from this “star” is most concentrated is at the centre.
What is light?Light is a form of electromagnetic radiation that makes things visible or enables the human eye to see. It can also be described as radiation that is visible to the human eye. Light contains photons, which are little energy packets. Light never deviates from a straight course
The spot where the light is most concentrated would be at the center. The light is most dense at the center of the flashlight. It will show brightly at the center where the light is disbursed.
The spot where the light from this “star” is most concentrated is at the centre.

What is the atomic number for titanium
The setting sun is actually visible after it has dropped below the horizon due to the bending of light waves entering the atmosphere at a non-perpendicular angle to the surface, a process known as?
Refraction is the process in which light will bend away or towards the normal at the point of incidence when light comes from one optical medium to another optical medium.
During sunset, sun is still visible after it has dropped below the horizon.It is so because the light coming from sun is refracted when it passes through the atmosphere.
Our atmosphere has not a constant density.It varies depending its position from earth surface. Hence, refractive index of each layer of atmosphere varies which results in the refraction of sun light for which sun is visible though it is geometrically below the horizon.
Hence, the correct answer to the question is refraction.
an object increases its velocity from 22m/s to 36 m/s in 5s. what is the acceleration of the object?
The acceleration of the object is 2.8 [tex]m/s^2[/tex].
Given the following data:
Initial velocity = 22 m/s. Final velocity = 36 m/s. Time = 5 seconds.To find the acceleration of the object:
Mathematically, acceleration is given by the formula;
[tex]A = \frac{V\; - \;U}{t}[/tex]
Where:
A is the acceleration. V is the final velocity. U is the initial velocity. t is the time measured in seconds.Substituting the parameters into the formula, we have;
[tex]A = \frac{36 \; - \;22}{5}\\\\A = \frac{14}{5}[/tex]
Acceleration, A = 2.8 [tex]m/s^2[/tex]
Therefore, the acceleration of the object is 2.8 [tex]m/s^2[/tex].

Explain what would most likely happen to cloud formation if the humidity increases. Use complete sentences and give at least two supporting details.
Please do not copy off the internet, and put it in your own words.
Clouds are formed when the moisture content in the atmosphere is saturated. Thus as humidity increases, cloud formation also increases.
What is humidity?Humidity can be defined as the concentration of water vapor in the air. Thus, if there is high amount of water vapour humidity will be high. High humidity can be result in bad weather conditions such as hurricanes.
Clouds are formed by gases , when the air is saturated with water vapour. That is at the point where, maximum water content is accommodated in air.
The moisture, atmospheric gases and dust clog together to form clouds. Hence, as the humidity increases more water content can be accommodated in air and thereby more tends to form clouds in atmosphere.

Increased humidity leads to higher chances of cloud formation as more water vapor is available in the air to condense around particles, creating moisture droplets which become clouds.
If humidity increases, cloud formation is more likely because humidity refers to the amount of water vapor in the air. When the air is moist and ascends, it cools and reaches a point where the water vapor can condense around particles known as condensation nuclei.
As relative humidity approaches 100%, condensation is likely to occur, particularly when tiny particles like dust or smoke are available to act as nuclei that the water vapor can condensate on, forming visible clouds.
A child weighs 300 N. What is the child's mass
The mass of a child of weight 300 N is calculated by dividing the weight by the standard acceleration due to gravity (9.8 m/s^2). Thus the child's mass is approximately 30.6 kg.
Explanation:The weight of an object is the force of gravity on it and can be calculated by multiplying the mass of the object by the gravitational constant. The child's weight is given as 300 N. Based on the standard acceleration rate due to gravity, which is about 9.8 m/s2, we can find the mass using the formula W=mg where W is weight, m is mass, and g is gravity. Therefore, m=W/g which gives us m=300 N/9.8 m/s2 which is approximately 30.6 kg.
