The doppler effect states that the motion of any object can ________
pshichka [43]

Answer:

shift the wavelength of spectral lines

Explanation:

The Doppler effect is commonly used in the field of astronomy to study the motion of astronomical objects such as a star, planets, and distant galaxies. This results in the changing of wavelength and shifting of the spectral lines, due to the relative and continuous motion of the receiver and the source. This is known as the red-shifting, where the lights in the spectrum move towards the highest wavelength, i.e towards the red light. This Doppler effect signifies that the distance between the distant galaxies and earth increases with the increasing recessional velocity.

Batteries are rated in terms of ampere-hours (A·h). For example, a battery that can produce a current of 2.00 A for 3.00 h is ra
Reptile [31]

(a) 423 J

The power of the battery is the ratio between the total energy stored (E) and the time elapsed (t):

P=\frac{E}{t}

However, the power is also the product of the voltage (V) and the current (I):

P=VI

Linking the two equations together,

\frac{E}{t}=VI\\E=VIt

Since we know:

V = 9.0 V

I \cdot t = 47.0 A\cdot h

We can calculate the total energy:

E=(9.0 V)(47 A \cdot h)=423 J

(b) 7.79\cdot 10^{-6} dollars

The battery has a total energy of E = 423 J. (2)

1 Watt (W) is equal to 1 Joule (J) per second (s):

1 W = \frac{1 J}{1 s}

so 1 kW corresponds to 1000 J/s:

1 kW = \frac{1000 J}{1 s}

Multiplying both side by 1 hour (1 h):

1 kW \cdot h = \frac{1000 J}{1 s} 1 h

and 1 h = 3600 s, so

1 kWh = \frac{1000 J}{1 s}\cdot 3600 s =3.6\cdot 10^6 J

So we find the conversion between kWh and Joules. So now we can convert the energy from Joules (2) into kWh:

1 kWh = 3.6\cdot 10^6 J = x : 423 J\\x=\frac{1 kWh \cdot 423 J}{3.6\cdot 10^6 J}=1.18\cdot 10^{-4}kWh

And since the cost is $0.0660 per kilowatt-hour, the total cost will be

C=$0.0660\cdot 1.18\cdot 10^{-4} kWh=7.79\cdot 10^{-6} dollars
