An astronaut is standing on the surface of a planetary satellite that has a radius of 1.74 times 10^6 m and a mass of 7.35 times

10^22 kg. An experiment is planned where a projectile needs to be launched straight up from the surface. What must be the minimum initial speed of the projectile so it will reach a height of 2.55 times 10^6 m above this satellite's surface? (G = 6.67 times 10^-11 N middot m^2/kg^2)

Is yeast a livingthings? And explain the answer (how do you know?)
Ket [755]
Yeast is a living organism, and it respires or breathes, through its cells. During the respiration process, glucose and oxygen are combined and turned into C0₂, also known as carbon dioxide. It's also converted into alcohol which releases energy from the cell(s). The term "respiration" that was used, derives from any chemical process which releases energy from food. As a side note, yeast is a unicellular organism, meaning that they only have one cell, but deriving from multicellular ancestors. 

I hope I helped :)

Suppose a 0.04-kg car traveling at 2.00 m/s can barely break an egg. What is the min
Paha777 [63]

Answer: The correct answer is option (A).

Explanation:

Momentum of the car with 0.04 kg mass , which travelling with velocity of 2.00 m/s

P_1=mass\times velocity=m_1\times v_1=0.04 kg\times 2.00 m/s=8.00 kg m/s

Then the maximum speed of the another car in order to not to break the eggs will be same as first car:

P_1=P_2

0.08 kg m/s=m_2\times v_2=0.08 kg\times v_2

v_2=1 m/s

Speed slightly more than 1 m/s will increase the momentum of second car and the eggs will break. So, from the given options the minimum speed need by the second car will be 1.42m/s.
