Bohr's model of the atom shows that electrons follow a definite orbit with distinct distances away from the nucleus. The electron cloud on the other hand suggests that the electrons are within a cloud without a definite orbit. The locations of electrons are based on probability that they are there.

To solve this problem it is necessary to apply the equations given from Bernoulli's principle, which describes the behavior of a liquid moving along a streamline. Mathematically this expression can be given as,
Where,
Pressure at each state
= Density
Velocity
Re-organizing the expression we can get that
Our values are given as
Normal Conditions
Replacing we have,
If we consider that there is a balance between the two states, the Force provided by gravity is equivalent to the Support Force, therefore
Here the lift force is the product between the pressure difference previously found by the effective area of the aircraft, while the Force of gravity represents the weight. There,
Equating,
Therefore the weight of the plane is 14535N
Answer:
14 m/s²
Explanation:
Start with Newton's 2nd law: Fnet=ma, with F being force, m being mass, and a being acceleration. The applied forces on the left and right side of the block are equivalent, so they cancel out and are negligible. That way, you only have to worry about the y direction. Don't forget the force that gravity has the object. It appears to me that the object is falling, so there would be an additional force from going down from weight of the object. Weight is gravity (can be rounded to 10) x mass. Substitute 4N+weight in for Fnet and 1kg in for m.
(4N + 10 x 1kg)=(1kg)a
14/1=14, so the acceleration is 14 m/s²
Here’s 3 examples:
MCB is more sensitive to current than fuse.
In case of MCB, the faulty zone of electrical circuit can be easily identified.
With MCB it is very simple to resume to the supply.
