Answer:
panic anxiety
Explanation:
Panic anxiety occur unexpectedly, sometimes even when waking up from sleep characterized by its unexpectedness and debilitating, immobilizing intensity it is caused by Severe stress, such as the death of a loved one, divorce, or job loss can also trigger panic anxiety. Panic attacks can also be caused by medical conditions and other physical cause e.g sitting in a position for hours under an unfavorable condition doing a recurring activity.  Panic anxiety may occur as part of another disorder, such as panic disorder, social phobia, or depression. Regardless of the cause, panic attacks are treatable.
 
        
             
        
        
        
Answer:
a) the charge of an electron is equivalent to the magnitude of the elementary charge but barring a negative sign since the side of the elementary charge is roughly 1.602 * 10 - 19 Columbus then the charge of the electronic is-1.602 * 10 - 19
b) b=2T on the electron moving in the magnetic field

The sketch of the two cases has been attached to this response. 
<em>Case 1: The box is pushed by a horizontal force F making it to move with constant velocity.</em>
In this case, a frictional force  is opposing the movement of the box. As shown in the diagram, it can be deduced from Newton's law of motion that;
 is opposing the movement of the box. As shown in the diagram, it can be deduced from Newton's law of motion that;
∑F = ma    -------------------(i)
Where;
∑F = effective force acting on the object (box)
m = mass of the object
a = acceleration of the object
∑F = F -  
m = 50kg
a = 0   [At constant velocity, acceleration is zero]
<em>Substitute these values into equation (i) as follows;</em>
F -   = m x a
 = m x a
F -   = 50 x 0
 = 50 x 0
F -   = 0
 = 0
F =   -------------------(ii)
            -------------------(ii)
<em>Case 2: The box is pushed by a horizontal force 1.5F making it to move with a constant velocity of 0.1m/s²</em>
In this case, the same frictional force  is opposing the movement of the box.
 is opposing the movement of the box.
∑F = 1.5F -  
m = 50kg
a =  0.1m/s²
<em>Substitute these values into equation (i) as follows;</em>
1.5F -   = m x a
 = m x a
1.5F -   = 50 x 0.1
 = 50 x 0.1
1.5F -   = 5            ---------------------(iii)
 = 5            ---------------------(iii)
<em>Substitute </em> <em> = F from equation (ii) into equation (iii) as follows;</em>
<em> = F from equation (ii) into equation (iii) as follows;</em>
1.5F - F = 5            
0.5F = 5            
F = 5 / 0.5
F = 10N
Therefore, the value of F is 10N

Answer:
 true
Explanation:
 Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
