Explanation:
Wind waves are the surface waves that occurs on the free surface of water. They result from wind blowing over an area of the surface of water.
The energy is transferred from the wind in waves across the ocean.
Wave height of the ocean is affected by wind speed. If the speed of the wind is slow then only small waves will occur.
When wind moves at high speed then it transfers more energy to the water. It will result in stronger waves.
Answer:I think the answer is Wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
Explanation: Because wind transfers energy to the ocean, if there are faster winds, more winds transfers more energy to the water.

A spaceship orbiting earth flies to the moon. How is the gravitational force pulling on the spaceship related to the distance that the spaceship is from the earth? As the distance from the earth decreases, the gravitational pull on the spaceship would decrease. The gravitational pull of the earth is constant and therefore the gravitational pull on would not change. There is no gravity on the moon and therefore only the earth will exert gravitational force on the spaceship. As the distance from the earth increases, the gravitational pull on the spaceship would decrease.
when the air in a submarine's huge air tanks is decompressed and it displaces the water in the ballast tanks with air, what does the submarine do?
A. It sinks B. It floats C. It provides air to the passengers
Decompressing the air in a submarine's air tanks displaces the water in the ballast tanks with air, reducing the submarine's density and making it float. Therefore, the correct answer is B. It floats.
The student asked, "When the air in a submarine's huge air tanks is decompressed and it displaces the water in the ballast tanks with air, what does the submarine do? A. It sinks B. It floats C. It provides air to the passengers".
When the air in a submarine's huge air tanks is decompressed, it displaces the water in the ballast tanks with air. This action reduces the overall density of the submarine, making it less dense than the surrounding water, and as a result, the submarine floats.
Therefore, the correct answer is: B. It floats.

Which one of the following types of electromagnetic radiation causes certain substances to fluoresce?
A. Cosmic rays
B. X rays
C. Infrared waves
D. Ultraviolet rays
Final answer:
Ultraviolet (UV) rays are the type of electromagnetic radiation that causes substances to fluoresce by exciting their electrons.
Explanation:
The type of electromagnetic radiation that causes certain substances to fluoresce is ultraviolet (UV) rays. Fluorescence occurs when a substance absorbs this radiation and then emits light. Ultraviolet rays have higher energy (as opposed to infrared waves, for example) and can excite electrons in a substance to a higher energy level. When these electrons return to their original energy state, they release energy in the form of visible light, causing the substance to appear to glow or fluoresce.
The largest salami in the world, made in Norway, was more than 20 m long. If a hungry mouse ran around the salami’s circumference with a tangential speed of 0.17 m/s, the centripetal acceleration of the mouse was 0.29 m/s2 . What was the radius of the salami?
Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
[tex]a_c=\frac{v^2_t}{r}[/tex]
where r is the radius.
It is given that,
centripetal acceleration of the mouse, [tex]a_c=0.29 m/s^2[/tex]
tangential speed , [tex]v_t=0.17m/s[/tex]
Radius of salami is:
[tex]r =\frac{(0.17m/s)^2}{0.29 m/s^2}=0.09m[/tex]
Thus, the radius of the salami is 0.09 m.
Given the tangential speed of 0.17 m/s and the centripetal acceleration of 0.29 m/s², the radius of the salami is approximately 0.09 meters.
The formula for centripetal acceleration in terms of tangential speed is:
ac = v_t² / r
where r is the radius.
Given:
- Centripetal acceleration of the mouse, ac = 0.29 m/s²
- Tangential speed, v_t = 0.17 m/s
To find the radius r of the salami:
r = (v_t²) / ac
r = (0.17 m/s)² / 0.29 m/s²
r = 0.09 meters
Thus, the radius of the salami is 0.09 meters.
a plane takes off at 34 m/s if it accelerates from rest and takes 7.2 seconds to lift off find the acceleration

The spring in a toy rocket launcher has a spring constant of 13 N/m. How far must you compress the spring to cause it to exert a force of 2.5 N?
Answer:
Distance, x = 0.19 meters
Explanation:
It is given that,
Spring constant of the toy rocket, k = 13 N/m
Force applied on the spring, F = 2.5 N
We have to find the spring constant of the spring. It can be calculated using Hooke's law as :
F = - kx
[tex]x=\dfrac{F}{k}[/tex]
[tex]x=\dfrac{2.5\ N}{13\ N/m}[/tex]
x = 0.19 meters
Hence, the spring must be compress to cause it to exert a force of 2.5 N.

Radio Stations
Ultraviolet Waves
Gamma Rays
Microwaves
The waves that have shorter wavelengths than visible light are gamma rays and UV rays. Microwaves and radio waves are longer waves than visible light.
What is electromagnetic spectrum ?The electromagnetic spectrum is the arrangement of waves in the order increasing frequency or decreasing wavelength. The order of the spectra starts from radio waves, microwaves, infrared, visible light, ultraviolet, x -rays and gamma rays.
The visible light that we can see is in between IR and UV rays. Hence, visible light has a frequency greater than IR rays but shorter than IR. Similarly visible light is longer than UV- rays but less frequency than UV rays.
Gamma rays are the most energetic and shorter waves in the electromagnetic spectrum with smaller wavelength and greater frequency. Hence, options b and c are correct.

imagine you are asked to push a heavy box across the floor. At first you need to push very hard but once the box has started move you can push less strongly yet still keep it moving. Why is it
To push a heavy box, more force is initially required to overcome static friction than kinetic friction once it's moving. Adding mass increases the required force, and reducing friction with oil makes the process easier.
Pushing a heavy box across the floor requires different amounts of effort due to the static and kinetic friction forces at play. Initially, a greater force is required to overcome static friction, which is the resistance to motion that occurs when two objects are not moving relative to each other. Once the box begins to move, only kinetic friction, which is generally less than static friction, opposes the motion, hence less force is needed to keep the box moving.
If you add mass to the box, such as placing another box on top, you would have to exert more force to both start and maintain its movement. Surfaces with higher friction require more effort to move an object across them, which is why it's harder to push heavy objects on rough surfaces compared to smooth ones. Moreover, when a surface is oiled, friction is reduced, making it easier to start and continue the movement of the box.

during sublimation particles in a solid room deodorizer move directly into the air as a gas how does the movement of the deodorizer particles change? the particles ___.
A) move fast enough that the attraction between particles is overcome completely
B) Lose enough energy that the movement completely stops
C) Move slowly enough that strong attractions form, pulling the particles together
D) Are only able to slip and slide past each other
Answer: Option (A) is the correct answer.
Explanation:
Sublimation is a process in which molecules of a solid substance are converted directly into gaseous phase without undergoing liquid phase.
This is because solid particles absorb the heat from their surroundings due to which bond between the molecules are broken down. As a result, molecules gain kinetic energy and they move rapidly into the atmosphere.
Thus, we can conclude that in the given situation the particles move fast enough that the attraction between particles is overcome completely.
