Answer:
<h2>
The magnitude of the magnetic is 0.145 T</h2>
Explanation:
Given :
Speed of proton 
Mass of proton 
Kg
The force on the proton in magnetic field is given by,
But 
(∵ Force is perpendicular to the velocity so 
)
When particle enter in magnetic field at the angle of 90° so particle moves in circle
So force is given by,
Where 
radius but in our case 0.23 m, 
C
By comparing above two equation,
T
Answer:he conducts the investigation to see the effect acidic water has on limestone
Explanation:
Answer:
Human activities and natural processes have influenced the change in the global temperature by the following processes
1) Green house gas such as carbon dioxide, methane, ozone, nitrous oxide and fluorinated gases produced by the combustion of fossil fuels the use of industrial chemicals, the production of coal, and natural gas
2) Deforestation which reduces the natural process of conversion of carbon dioxide to oxygen, thereby, increasing the greenhouse gases in the atmosphere
3) The accumulation of the greenhouse gases in the atmosphere results in the trapping of heat in the atmosphere, causing the atmospheric temperature to rise
4) Changes in the amount of energy produced by the Sun can result in an increase or decrease in the atmospheric temperature
5) Volcanic activity that occurs at a sufficiently large scale can produce sulfur dioxide that blocks the rays of the Sun from reaching the Earth, resulting in a change of atmospheric temperature.
Explanation:
Answer: Productivity increases when inputs and outputs increase proportionately.
Explanation:
Productivity increases when inputs and outputs increase proportionately. Input has to be directly proportional to output to be productive. This means increase in input to a system must leads to drastic increase in the output. When the output is not balanced with the amount of input, it leads to unproductivity.
Being productive can be business wise or in terms if personal growth and development.
Models help us to understand systems and their properties
