Answer:
10 kilograms
Explanation:
The formula for mass
mass (kg)= momentum ( p) divided by velocity (v)
therefore this translates to 50 divided by 5
which gives the final answer as <u>10kgs</u>
 
        
             
        
        
        
The plum pudding model, which has been abandoned since the discovery of the nucleus, stated that electrons were embedded in a "mush" of positive material. The nuclear model says they are placed around a central nucleus. 
        
             
        
        
        
The kinematics for the vertical launch we can enter the initial velocity is 11.76 m / s
Given parameters
To find
Kinematics is the part of physics that establishes the relationships between the position, velocity, and acceleration of bodies.
In this case we have a vertical launch
           y = y₀ + v₀ t - ½ g t²
Where y and y₀ are the final and initial positions, respectively, v₀ the initial velocity, g the acceleration of gravity (g = 9.8 m / s²) and t the time
    
With the ball in hand, its position is zero
          0 = 0 + v₀ t - ½ g t²
          v₀ t - ½ g t² = 0
          v₀ = ½ g t
Let's calculate
          v₀ = ½ 9.8 2.4
          v₀ = 11.76 m / s
In conclusion using kinematics for the vertical launch we can enter the initial velocity is 11.76 m / s

Answer; 
-it will move away from the large ball because like charges repel.
Explanation; 
-Electric force is the force that pushes apart two like charges, or that pulls together two unlike charges. The basic law of electrostatics Like charges of electricity repel each other, whereas unlike charges attract each other.
When small, positively charged ball is moved close to a large, positively charged ball it would be pushed away from the large positively charged ball since they are both positively charged. One has to put in energy to try to move the small ball closer to the large ball. The closer one try to move it to the large ball, the more energy one has to put in, so the more electrical potential energy the small ball would have.
