Answer:
The new radius is three times the initial radius
Explanation:
The magnetic force is given by the equation
        F = q v x B
Where the blacks indicate vectors, q is the electric charge, v the velocity of the particle and B the magnetic field. The scalar magnitude of this force is
      F = q v B sin θ
Where θ is the angle between the velocity and the magnetic field.
As the force is perpendicular to the velocity, the particle describes a circular motion, using Newton's second law we can find the acceleration that is centripetal.
     F = ma
     a = v² / r
    
    q v B = mv² / r
   R = mv / qB
Let's calculate for the new speed (v₂ = 3v)
   R₂ = (m / qB) 3v
  R₂ = 3 R
  R₂ / R = 3
The new radius is three times the initial radius
 
        
             
        
        
        
So we know coefficient of f times normal force is friction. So do 100= .25 times x. Now solve for x. You get 400. So 400 is the normal force. And we know normal force equals weight in these types of problems so the answer is 400
        
             
        
        
        
Answer:
The factors that affects the carrying capacity are the "food availability,  water supply, environmental condition and living space"
Explanation:
The carrying capacity of an environment varies in different species and there are chances of being change over the time because of the various factors which is like food availability, water supply, environmental condition ad also the living space. The carrying capacity is mostly dependent upon the available resources and also the  services available in the ecosystem. The symbol for the carrying capacity is K. If the population size will increase the carrying capacity are not sustainable and hence it will degrade the habitat.
 
        
             
        
        
        
Answer:
in computer and writing context it is many styles of writing that you can make the text look like. I.E: <em>helllo  </em>hello
Explanation:
A font is the combination of typeface and other qualities, such as size, pitch, and spacing. For example, Times Roman is a typeface that defines the shape of each character. Within Times Roman, however, there are many fonts to choose from -- different sizes, italic, bold, and so on.

Answer:
D. It must have mass and volume
Explanation:
In science, matter is referred to as any substance that has weight and occupies space. This means that the substance must have a MASS of its own when weighed and also a VOLUME.
Matter include elements, molecules, humans, etc. In fact, almost every substance on Earth is considered MATTER. Therefore, the fact that a substance must "have mass and volume" is true for all matter.
