Copper is a better conductor.
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.
To solve this problem we will apply the concept of Impulse. Which is described as the product between the Force and the change in time. Mathematically this can be described as
Where,
F = Force
= Time
Our values are given as,
F = 1450N
Replacing we have,
Therefore the impulse delivered to the soccer ball is 
or 
Answer:
780 J
Explanation:
W=\int _{\:0}^{50}0.624xdx
