Answer:
The high-beam filament has more resistance than low beam filament.
Explanation:
To determine if the 50 W dissipated by a car’s headlights on high beam, has more or less resistance, formula for power dissipated in the filament is used.
Power = IV
Voltage =IR
∴ Power = I*IR = I²R
where;
I is the current
V is the voltage
R is the resistance
From the equation above, Power dissipated is directly proportional to Resistance.
Hence, the high-beam filament has more resistance than low beam filament.
Answer:
Explanation:
Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.
Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.
scale = 
= 
= 
scale = 1:40
This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.
The man's direction is
north of east.
The graphical drawing of the vector is herewith attached to this answer.
