Answer:
Explanation:
Current drawn by electric heater = power/volt =1500/120 = 12.5 A.
current drawn by hair drier at 600 watt = 600/120 =5 A
current drawn by hair drier at 900 watt = 900/120 = 7.5 A.
Total current drawn by heater and hair drier used at 900 watt
= 12.5 + 7.5 = 20 A
Breaking current =20 A
So fuse will trip at this point .
Answer:
-30°C
Explanation:
F-32/180 =C-0/100
or, -22-32/180=C/100
or, -54/180*100=C
or, -0.3*100=C
therefore, C= -30
-22°F = -30°C

Answer:s=0.68 m
Explanation:
Given
Inclination 
Speed of block(u)=1.6 m/s
Coefficient of kinetic Friction 
deceleration provided by friction=g\sin \theta -\mu _kg\cos \theta [/tex]
Using 
Final velocity v=0


s=0.68 m
Water that flows across the surface is called a;
Runoff
That's when rain has saturated the ground to the point it cant hold anymore and it runs over the surface.
