Answer:
Chloroplasts are the site of photosynthesis in the cell and it also consists of a double membrane. it relates to the solar panels of an amusement park because both things take energy from the sun and use it to provide energy for their systems.
This is a type of transmission called contact transmission.
Contact transmission is the most common form of transmitting diseases and virus. Contact transmission any be direct or indirect transmission. Direct contact transmission occurs when there is a physical contact between an infected person and the susceptible person. Indirect transmission occurs when there is no direct human -to human contact. Contact occurs from a reservoir to contaminated surfaces or objects.
In this problem we will use the formula: f = c/λ
Wherein: f = frequency
c = speed of wave
λ = wavelength of wave
500 km/h / 200 km = 2.5 Hz
<span>In this problem, speed and the distance between
crests are given. Therefore, all you have to do is to divide the speed by the wavelength
to determine the frequency using the formula provided.</span>
