Answer:

Explanation:
Drag force is given by

C = Drag coefficient is constant
A = Area is constant
= Velocity of the passenger jet = 1200 km/h = 
= Velocity of the prop plane = 
= Density of the air where the jet was flying = 
= Density of the air where the prop plane was flying = 


The ratio of the drag forces is
.
Answer:
7...is mitochondria :- mitochondria are known as the power house of the cell.
Answer: To keep it basic start with temprature and inhibitors such as drugs that slow enzymes
surface area, temperature, concentration, and the presence of catalysts and inhibitors
Explanation:To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of catalysts and inhibitors. Temperature - Changing the temperature of a chemical reaction also affects the reaction rate.
Answer:
The pulling force F is 200 N
Explanation:
We note that the tension in a rope between two or three blocks is given by the relation;
Where we have;
m₁ → T₁ → m₂ → T₂ → m₃ → F


m₁ = 2 kg
m₂ = 4 kg
m₃ = 4 kg
T₂ = 120 N
Therefore, by substitution, gives;
2 kg → T₁ → 4 kg → 120 N → 4 kg → F

F = 120 N × (10 kg)/(6 kg) = 200 N
The pulling force F = 200 N.
