For a flat coil of wire has an inductance of 40. 0 mh and a resistance of 6. 00 ω, the rate of energy being delivered is mathematically given as
P= 53 W
<h3>What rate is
energy being delivered by the
battery?</h3>
Generally, the equation for the Battery power is mathematically given as
P = I (dt)V
Therefore
P= 2.50 A * 21.2V
P= 53 W
In conclusion, rate of energy being delivered
P= 53 W

Answer:
no
Explanation:
i don,t think so the averge of the car speed is faster
Density=mass/volume
mass= 5kg
volume: πr²h
= π(2)²(5)
=62.83 cm³ or 0.06283 m³
density: m/v
d= 5/0.06283 m³
d=79.57 kg/m³
Hope I helped :)
Answer:
Electrostatic field is a conservative field. That is work done when a charge is moved between two points is independent of path taken. Hence answer is W1
Answer:
The power of sports car is 25 times power of older model car
Explanation:
Consider mass of the two cars are same and is denoted by m.
Kinetic energy of older model car is determine by the relation:
Kinetic energy of sports car is determine by the relation:
....(1)
Power is defined as energy per unit time.
According to the problem, the car has only kinetic energy. So, the power of old model and sports car are determine by the relation:
and
Here P₁ and P₂ are the power of old model and sports car respectively.
The ratio of power of these car is:
Substitute equation (1) in the above equation.
