Answer:
counterclockwise
Explanation:
given data
area = 25 cm²
solution
We know that a changing magnetic field induces the current and induced emf is express as
..................................1
and we will get here direction of the induced current in the loop that is express by the Lens law that state that the direction of induces current is such that the magnetic flux due to the induced current opposes the change in magnetic flux due to the change in magnetic field
so when magnetic field decrease and point coming out of the paper.
so induced current in the loop will be counterclockwise
The charge on each coin is equal to
Given the following data:
Force = 2.0 Newton
Radius = 1.5 meters
To determine the charge on each coin, we would apply the law of electrostatic forces:
Mathematically, the law of electrostatic forces is given by the formula:
Note: (since the coin carry identical electric charges).
Therefore, the formula becomes:
Making q the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Answer:
Momentum of alpha particle is 1.4752x10^-19 kg-m/s
Explanation:
Detailed explanation and calculation is shown in the image below
Answer:
Atelectasis
Explanation:
Atelectasis is defined as the partial or completely collapsion of lungs, it is caused because of the collapse of tiny sacs of lungs or with the possibility, that these space is filled by the alveolar fluid.
Atelectasis is the condition in which the surface area of the alveolar is collapse, this can be caused due to the absence of surfactants. This condition will result in decrease or reduction of gas exchange.
