Answer:
wavelength is 20.71 cm
Explanation:
given data
wave = 43.0 vibrations
time = 29 s
wave travels = 430 cm
time t2 = 14 s
to find out
wavelength
solution
we know here wavelength formula that is
wavelength = velocity / frequency .........................1
here frequency = 43 / 29 = 1.4827 Hz
and velocity = 430 / 14 = 30.71 cm/s
so here from equation 1 put all value
wavelength = velocity / frequency
wavelength = 30.71 / 1.4827
wavelength = 20.71 cm
so wavelength is 20.71 cm
Two sustainability challenges you would face when developing a sustainable food supply for a Martian colony would relate to Martian radiation and soil characteristics.
According to experiments carried out, Martian radiation is about 17 times more intense than on Earth, which impacts vegetation growth and crop quality.
Therefore, it is necessary to develop resources that enable a sustainable food supply in remote locations, such as for a Martian colony, as some production challenges may be related to food resistance and the amount of oxygen and water needed for growth.
Some solutions, therefore, could be planting in an underground shelter, which would be a controlled environment where conditions would be more favorable for the production of food with greater quality and diversity.

Answer:
Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement
Explanation:
Answer:
I am confused of your question. Do you want final velocity? To get final velocity, use (initial V)+(Gravity*Time)
Explanation:
Answer:
Is always towards the center of the Earth
Explanation:
As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the center of the Earth. At an altitude of 100 km, you would be so high that you would see black sky and stars if you looked upwards.
