Answer:
The batteries would be connected in series while the bulbs would be connected in parallel
Explanation:
Power (W) = VI
where V = voltage, I = current and R = resistance
from V = IR , I = V/R
Power (W) now becomes = V (V/R) = 
Power (W) =
from the above equation, power is directly dependent on voltage, hence the voltage has to be high for the power to be high and the power is also inversely dependent on the resistance (in this case the bulbs which act as the load)
- We have to batteries, when batteries are connected in series the total voltage becomes the summation of the two voltages hence giving a higher voltage and when they are connected in parallel their voltage remains the same. Since we want to get higher voltage we will connect the two batteries in series.
- we have two bulbs which are the resistance here, from the equation above the power is inversely dependent on the resistance so we would need its value to be minimal. When resistance is connected in series the resistance individual will be added to get the total resistance, hence the total resistance will be high but when the resistors are arranged in parallel you get the total resistance by applying the formula
which will give us a lower resistance. Hence we would connect the bulbs in parallel.
Take note that the power from this connection should not exceed the bulbs power rating so as to avoid damage of the bulbs.
Answer:
They can be rank in the following way:
- A radio signal from an AM radio station at 680 kHz on the dial
- Radiation from an FM radio station at 93.1 MHz on the dial
- The red light of a light-emitting diode, such as in a calculator
- The yellow light from sodium vapor streetlights
- The gamma rays produced by a radioactive nuclide used in medical
Explanation:
The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, which are transverse waves formed by an electric field and a magnetic field perpendicular to it.
Radiation is distributed along that electromagnetic spectrum according to the wavelength or frequency.
Highest frequencies
X-rays
Ultraviolet rays
Visible region
Lower frequencies
Infrared
Microwave
Radio waves
Radio waves and the visible region (yellow light, red light) are part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of 3.00x10^{8}m/s in vacuum.
However, the following equation relates the velocity, the frequency, and the wavelength:
(1)
(2)
It can be see in equation 2 that the frequency and the wavelength are inversely proportional (when the frequency increases the wavelength decreases).
Therefore, for what was already discussed, they can be rank in the next way:
- A radio signal from an AM radio station at 680 kHz on the dial
- Radiation from an FM radio station at 93.1 MHz on the dial
- The red light of a light-emitting diode, such as in a calculator
- The yellow light from sodium vapor streetlights
- The gamma rays produced by a radioactive nuclide used in medical
Summary:
In the case of the radio waves can be used:

Do you have multiple choice answers? the lower layers are generally older than the higher layers.
Answer: Distance
I’m not sure if it is correct, but I am pretty sure it is......
I hope this helps :)
