Answer:
Explanation:
Given
mass of steel ball 
initial speed of ball 
Final speed of ball 
 (in upward direction)
Impulse imparted is given by change in the momentum of object
therefore impulse J is given by 




so magnitude of Impulse =4 N-s
 
        
                    
             
        
        
        
Answer:
The current can't 'split down the parallel branch, because the diode is reverse biased so is blocking the flow of current. So basically it's acting as an open circuit. Also when the current flows it wouldn't reduce the currents amount flow through the resistor.

The term which is considered as being undefined is referred to as a point and is therefore denoted as option A in this context.
<h3>What is a Point?</h3>
This is defined as as small round mark written on a plane which signifies the position or location of a substance. This can also be seen as a dot and is also used to separate a group of numbers such as in the case of decimals etc.
It is referred to as being undefined alongside a plane, line etc as a result of it only being explained using specific examples and descriptions unlike a segment which can be viewed and understood easily when working on the parameter.
This is therefore the reason why a point is undefined and the most appropriate choice.

Answer:
emf = 11.667 V
Explanation:
Given: charge q = 0.060 C, electric potential energy E =0.70 J, 
 Solution :
by definition 1 volt = 1 joule per coulomb
so Voltage = emf = E/C
emf =  0.70 J / 0.060 C
emf = 11.667 V
 
        
                    
             
        
        
        
Answer:
(C) an increase in tue distance between the ibject causes a greater change in the gravitational force than the same increase in mass
