Answer:
Why do insects fly so high?
Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift.
Why an Aeroplane flying has kinetic
A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energ
Explanation:
1. If Maggie gives her cat an unfair advantage, her experimental results will be biased.
Explanation:
Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.
- Due to her emotional attachment with the cat, the experimental results will be skewed to portraying her cat as intelligence.
- This is not a good experiment to carry out.
- Such an experiment should be carried out with an unknown cat.

Answer:
The mass of the block, M =T/(3a +g) Kg
Explanation:
Given,
The upward acceleration of the block a = 3a
The constant force acting on the block, F₀ = Ma = 3Ma
The mass of the block, M = ?
In an Atwood's machine, the upward force of the block is given by the relation
Ma = T - Mg
M x 3a = T - Ma
3Ma + Mg = T
M = T/(3a +g) Kg
Where 'T' is the tension of the string.
Hence, the mass of the block in Atwood's machine is, M = T/(3a +g) Kg
