How would you change the distance between two positively charged particles
to increase the electric potential energy by a factor of 4?
A. Reduce the distance by a factor of 16.
OOO
B. Increase the distance by a factor of 16.
C. Reduce the distance by a factor of 4.
O
D. Increase the distance by a factor of 4.
Answers
Answer:
Reduce the distance by a factor of 4.
Explanation:
The electric potential energy between two charged particle is given by :
\(U=\dfrac{kqQ}{r}\)
k is electric constant
r is distance between two positively charged particles
Electric potential energy is inversely proportional to the distance between charges. If we decrease the distance between charges by a factor of 4, the electric potential energy will increase by an factor of 4.
Hence, the correct option is (C).

The air currents across the continents would determine the distribution of the air.
What are air currents?Air currents across the continents are primarily driven by temperature differences and the rotation of the Earth. The warm air near the equator rises and flows towards the poles, while the cooler air near the poles sinks and flows towards the equator.
This creates large-scale circulation patterns known as Hadley cells, Ferrell cells, and Polar cells. These cells are responsible for the trade winds, westerlies, and easterlies, respectively. Additionally, there are also local winds caused by differences in terrain, such as sea breezes and valley breezes.

Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

Nuclear waste
Explanation:
It is extremely radioactive and can remain radioactive for hundreds of years.

They also cosmetically damage skin and the environment with chemicals.
What are the effects of radiation on different surfaces such as an ice- covered lake, a forest, an ocean, or an asphalt road?
Answers
Radiation can affect different surfaces in different ways depending on various factors. For instance, ionizing radiation can break apart water molecules in an ice-covered lake and damage plant cells in a forest, whereas non-ionizing radiation can support photosynthesis and growth. In the ocean, radiation can have both positive and negative effects, and exposure to high levels of ionizing radiation can cause damage to the asphalt of a road over time.
What is the effect of radiation?The effects of radiation on different surfaces can vary depending on a number of factors, including the type of radiation, the intensity of the radiation, and the properties of the surface material.
When radiation interacts with matter, it can cause a range of effects, including ionization, excitation, and heating. These effects can lead to changes in the physical and chemical properties of the material.
For example, when ionizing radiation (such as gamma rays or X-rays) interacts with water molecules in an ice-covered lake, it can break apart the water molecules and produce highly reactive free radicals. These free radicals can then go on to react with other molecules in the water, leading to changes in the chemical composition of the ice. The effects of radiation on a forest would depend on the type of radiation and the type of trees and plants present. High levels of ionizing radiation can damage or kill plant cells, leading to a reduction in growth and productivity. Non-ionizing radiation (such as visible light) can be used by plants for photosynthesis and growth.
In the case of an ocean, radiation can have a range of effects depending on the depth of the water and the type of radiation. For example, visible light can penetrate several hundred meters into the ocean, allowing photosynthetic organisms such as phytoplankton to thrive. On the other hand, ionizing radiation from radioactive materials can accumulate in the bodies of marine organisms, potentially leading to long-term health effects.
On the other hand, the effects of radiation on an asphalt road would depend on the type of radiation and the composition of the road. For example, exposure to high levels of ionizing radiation can lead to the breakdown of the chemical bonds in asphalt, potentially causing the road to become brittle and crack over time. Additionally, radiation exposure can lead to the formation of free radicals in the asphalt, which can react with oxygen in the air and cause the road surface to become discolored or faded.
Therefore, the effects of radiation on different surfaces can vary depending on a range of factors, including the type of radiation, the intensity of the radiation, and the properties of the surface material.

What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
a) According to the heights of books, P.E(Y)< P.E(W)< P.E(Z)< P.E(X)
when arranged for lowest potential energy, book with the lowest mass will be placed in the lower position. Thus, relationship among masses, m(Y)< m(W)<m(Z)<m(X)
b) The arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.
