Dull (not shiny)
poor conductors of heat and electricity (they are insulators)
weak and brittle (they easily break or shatter when solid)
        
             
        
        
        
Explanation:
It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.
As both the loads are connected in parallel. Hence, total current will be calculated as follows.
                I = 
                  = 0.75 A + 0.75 A
                  = 1.5 A
                  = 
                  = 1500 mA
Relation between time and capacity of battery is as follows.
              Capacity = Current × time (in hour)
therefore,        time = 
                                 = 
                                 = 1.667 hr
Thus, we can conclude that the battery provide power to the load up to 1.667 hours. 
 
        
             
        
        
        
What's the relationship between total and partial pressure? The total pressure is the sum of the parcial pressures!
So for us, it would be: 
378= 212+101+x
where x is the parcial pressure of nitrogen. 
Now we count: 
378= 212+101+x
378=313+x
378-313=x
65=x
So the parcial pressure exerted by nitrogen is 65!
