Answer:
Explanation:
Given:
m=0.504kg
r=5.37mm
metal cylinde factor=2.31
we know that
Upward force = Downward force
Net force
For the first part of the trip:
we have velocity = 960 km/hr and distance = 2250 km
velocity = distance / time
time1 = distance / velocity = 2250 / 960 = 2.34375 hours
For the second part of the trip:
we have velocity = 805 km/hr and distance = 1320 km
velocity = distance / time
time2 = distance / velocity = 1320 / 805 = 1.63975 hours
For the total trip:
we have:
total distance covered = 2250 + 1320 = 3570 km
total time taken = 2.34375 + 1.63975 = 3.9835 hours
average velocity = total distance / total time
average velocity = 3570 / 3.9835 = 896.1968 km/hr
Answer:
The purpose or objective of the electromagnetic spectrum experiment the purpose is to figure out what elements are in the planets’ and the moons’ atmospheres by looking at their absorption spectrums
Explanation:
What is electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10^25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high frequency (short wavelength) end.
The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications.
The limit for long wavelengths is the size of the universe itself.
Don't know if this helps or not :)
Answer:
The ocean plays a leading role in the Earth's climate.
The ocean plays an important role in shaping our climate and weather patterns. Warm ocean waters provide the energy to fuel storm systems that provide fresh water vital to all living things.
