Answer:
Total distance = 400+700+1200= 2300km
Explanation:
the resultant of d 1st right angle triangle + 1200
= 806.2 + 1200 = 2006.2km
 
        
             
        
        
        
The formula we can use in this case is:
d = v0t + 0.5 at^2
v = at + v0
where,
d = distance travelled
v0 = initial velocity = 0 since at rest
t = time travelled
a = acceleration
v = final velocity when it took off
 
a. d = 0 + 0.5 * 3 * 30^2
d = 1350 m
 
b. v = 3 * 30 + 0
<span>v = 90 m/s</span>
 
        
             
        
        
        
Acceleration=(change in speed)/(time for the change). 43/0.28 = 153.6 m/s^2.
        
                    
             
        
        
        
Answer:
The metal will melt but their will be no change in temperature.
Explanation:
The metal is at its melting temperature which means it is still in solid phase but have to cross the enthalpy of its condensation at this same temperature to convert into liquid phase.
<u>On supplying heat, the metal's temperature will not change as the heat will be required as enthalpy of condensation to melt the solid to liquid at the melting temperature.</u>
