The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Write a report on waves. Some questions you might consider are: What makes a wave? Why are some waves small and some large? How are waves classified? Are there different kinds of waves? What happens when a wave meets the shore? Where in the world do you find the best waves for surfing?
Answers
Answer:
The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates. Portugal is one of the best places to surf because they have waves that can reach up to 6 to 15 feet high!

What two gases in the atmosphere do animals and plants need to breathe and grow?
Answers
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.
Assume that all of the objects in the diagram are solid and made of the same material.
In Set A, what would you have to do to the objects to make the gravitational forces between the objects in pair 2 the same as the forces between the objects in pair 1?
Answers
Answer:
You would have to decrease the size until they had the same masses.
Explanation:
Right now, pair two will be more attracted because of the larger size. If it decreased to the same size as pair one, the forces would be the same.

What are the three types of heat transfer in the Earth’s atmosphere.
Answers
Answer:
Radiation, conduction, and convection.
Explanation:
Radiation:
Radiation heat transfer occurs through electromagnetic waves. Unlike conduction and convection, radiation does not need a medium for transmission. Solar radiation energy traverses a 93-million-mile vacuum to warm the EarthConduction:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together, than in gases, where particles are farther apart.Convection:
The process by which heat is transferred by the movement of a heated fluid, such as air or water.Levi observed properties of four different waves and recorded observations about each one in his chart.

Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.
Explanation:
W travels fastest through metal
X travels fastest through air,
Y travels more slowly through water than air
Z travels more slowly at cool temperatures
W appears to be sound wave as sound travels fastest through metal .
X appears to be light wave as light travels fastest in air .
Y also appears to be light wave as speed of light is reduced when it passes from air to water .

Use the data in the table to explain how you could determine the volume of the block.
Answers
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

Erin is keeping a science journal. She wrote the following paragraph that explains how light travels through different mediums. But she’s made one mistake. Which sentence in Erin’s journal is incorrect?
A ray of light passes through the air and enters the water inside a metal container. The light ray bends as it crosses the boundary between air and water. Once it hits the bottom of the container, the ray gets reflected. The reflected ray passes back through the water and enters the air without bending. In this example, the ray of light is both reflected and refracted.

There are 200 turns of wire around an electromagnet. The current in the wire is 6 amp. You want to increase the strength of the magnet to 1.5 times its present strength. What are two changes you can make to achieve your goal? Show all your calculations.
Answers
Answer:
i. increasing the number of turns of the wire by half, so that it equals 300.
OR
ii. increasing the value of the current by half of its initial value, so that it equals 9 amp.
Explanation:
An electromagnet consists of a coil of wire wound around a conductor which becomes induced with magnetism when current flows through the coil.
The magnetic strength of the electromagnet can be increased to 1.5 of its initial strength either by;
i. increasing the number of turns by half of its initial value
OR
ii. increasing the current by half of its initial value
The magnetic strength of an electromagnet = I × N
where; I is the amount of current and N the number of turns.
Given that: I = 6 A, N = 200, then;
magnetic strength = 6 ×200
= 1200 Ampere turns
i. Increasing the number of turns to 300 and I = 6 A, we have;
magnetic strength = 6 × 300
= 1800 Ampere turns
OR
ii. increasing the value of current by half of its initial value, so that N = 200 and I = 9 A;
magnetic strength = 9 ×200
= 1800 Ampere turns
