b) Explain which one(s) hit the ground last
Answers
Explanation:
Balls A and C have the same initial vertical velocity of zero. Therefore, they land at the same time.
Ball B has a positive initial vertical velocity, so it hits the ground last.

A geostationary orbit, also known as a geosynchronous equatorial orbit, is a specific type of circular orbit around the Earth. In this orbit, a satellite's orbital period matches the Earth's rotation period, which is approximately 24 hours. This causes the satellite to appear stationary relative to a fixed point on the Earth's surface, which is why it's commonly used for communication, weather, and broadcasting satellites.
To achieve this, the satellite needs to be at a specific height above the Earth's surface. The altitude at which a satellite will have a period of one day (24 hours) is called the geostationary altitude or the geostationary orbit height.
The calculation to determine this altitude involves using the formula for the orbital period of a satellite:
Where:
- \( T \) is the orbital period (24 hours in this case)
- \( G \) is the gravitational constant
- \( M \) is the mass of the Earth
- \( r \) is the radius of the satellite's orbit (distance from the center of the Earth to the satellite)
Solving for \( r \) with the known values of \( T \), \( G \), and \( M \), you'll find that the satellite needs to be approximately 35,786 kilometers (22,236 miles) above the Earth's surface to have an orbital period of one day.
This altitude allows the satellite to complete one orbit around the Earth in the same amount of time it takes for the Earth to complete one rotation on its axis, effectively staying in the same position relative to a specific point on the Earth's equator.

An expansion card is a circuit board that can be attached to the motherboard to add features such as video display and audio capability to the computer.
Explanation:
An expansion card, also known as an add-in card or expansion board, is a hardware component designed to enhance a computer's capabilities by providing additional functionality. These cards can be attached to the motherboard of a computer to add various features or capabilities, including video display and audio processing.
Expansion cards come in various forms and serve different purposes. For example, a graphics card is a type of expansion card that is commonly used to improve a computer's graphics performance. It can handle complex graphical tasks, making it essential for gaming, video editing, and graphic design. Another common type is the sound card, which enhances a computer's audio capabilities, enabling high-quality sound output and input for tasks like music production and gaming.
The process of adding an expansion card involves inserting it into a compatible slot on the motherboard, securing it in place, and installing the necessary drivers and software to ensure proper functionality. Most motherboards have multiple slots to accommodate various types of expansion cards, allowing users to customize their computer's capabilities based on their specific needs.
In summary, expansion cards are crucial components that enable users to expand and upgrade their computer's capabilities, whether it's for gaming, multimedia, or other specialized tasks.
