Answer:
The  electrons are moving through the superconductor per second.
 electrons are moving through the superconductor per second.
Explanation:
Given : 
Current  A
 A
Charge of electron  C
 C
Time  sec
 sec
From the formula of current,
Current is the number of charges flowing per unit time.
    
Where  number of charges means in our case number of electrons
 number of charges means in our case number of electrons
    
    
    
Therefore,  electrons are moving through the superconductor per second.
 electrons are moving through the superconductor per second.
 
        
             
        
        
        
Since the electron dropped from an energy level i to the ground state by emitting a single photon, this photon has an energy of 1.41 × 10⁻¹⁸ Joules.
<h3>How to calculate the photon energy?</h3>
In order to determine the photon energy of an electron, you should apply Planck-Einstein's equation.
Mathematically, the Planck-Einstein equation can be calculated by using this formula:
E = hf
<u>Where:</u>
In this scenario, this photon has an energy of 1.41 × 10⁻¹⁸ Joules because the electron dropped from an energy level i to the ground state by emitting a single photon.

<em>Given that:</em>
                        mass of the ball (m) = 0.5 Kg ,
                     ball strikes the wall (v₁) = 5 m/s ,
 rebounds in opposite direction (v₂) = 2 m/s,
                                 time duration (t) = 0.01 s,
         <em> Determine the force (F) = ?</em> 
We know that from Newton's II law,
                                 <em>F = m. a</em>  Newtons  
                                   (velocity acting in opposite direction, so <em>a = ( (v₁ + v₂)/t</em>
                                    = m × (v₁ + v₂)/t
                                    = 0.5 × (5 + 2)/0.01
                                   = 350 N
<em>The force acting up on the ball is 350 N</em>
                                      
 
        
             
        
        
        
Answer:
m/s^2
Explanation:
Force = mass × acceleration
kgm/s^2 = kg × acceleration
where acceleration = Force ÷ mass
 = kg m/s^2 ÷ kg
:Acceleration = m/s^2
 
        
             
        
        
        
Answer:
force of gravity
Explanation:
The force of gravity is that which draws the bodies towards the surface of the Earth.
  The force of gravity brakes the objects that move up and accelerates those that move down. It causes a parabolic movement in what we throw upwards,
